The Canadian Centre for Cyber Security's National Cyber Threat Assessment 2025–2026 does not mince words: cyber threats to Canada are becoming more complex and sophisticated, threatening national security and economic prosperity. For Canadian business owners, the numbers behind that statement are sobering. The average cost of a data breach at a Canadian organization reached CA$6.98 million in 2025 — a 10.4% increase over the previous year (IBM Cost of a Data Breach Report, 2025). One in six Canadian businesses (16%) was directly impacted by a cybersecurity incident in 2023 (Statistics Canada), and the Canadian Anti-Fraud Centre recorded CA$704 million in reported fraud losses in 2025 — the highest annual figure on record.
Yet preparedness has not kept pace with the threat. Only 26% of Canadian businesses have written cybersecurity policies in place (Statistics Canada, 2023), and just 11% of Canadian SMBs have a formal incident response plan (Insurance Bureau of Canada, 2025). The gap between the severity of cybersecurity threats in Canada and the readiness of Canadian businesses is widening, not closing.
At NetFusion Designs, we have been providing managed cybersecurity services to Canadian businesses since 2006. As a SOC 2 certified managed service provider with offices in Kitchener, Toronto, Markham, Mississauga, Montreal, and Winnipeg, we have seen these threats evolve firsthand across more than 300 client organizations. This guide breaks down the 10 most critical cybersecurity risks for businesses operating in Canada in 2026 — and what you can do about each one.

1. Ransomware Attacks
Ransomware is the number one cybercrime threat facing Canada's critical infrastructure, according to the Canadian Centre for Cyber Security's NCTA 2025–2026. That assessment applies equally to small and mid-sized businesses — and in many ways, SMBs face even greater risk.
The Canadian Ransomware Picture
Canada recorded 352 ransomware cases in 2025, a 46% increase over the prior year (NordStellar). In Q4 2025 alone, Canada saw 107 cases — a 73% jump from Q3. The businesses absorbing the most attacks were organizations with 51 to 200 employees and revenues between $5 million and $25 million. That profile describes a large portion of Canadian companies: regional manufacturers, dental groups, accounting practices, logistics firms, and construction contractors.
The CIRA 2025 Cybersecurity Survey found that 74% of Canadian organizations that experienced ransomware ended up paying the ransom, with average payments nearing CA$25,000 (Insurance Bureau of Canada, 2025). However, the true cost of a ransomware incident extends far beyond the ransom itself. Total recovery costs associated with cybersecurity incidents in Canada doubled to approximately $1.2 billion in 2023 (Statistics Canada). When you account for downtime, emergency IT recovery, legal expenses, customer notification, and reputational damage, the financial burden often far outweighs the ransom demand.
Sophos's Active Adversary Report 2026 reveals two operational details every Canadian business should plan for: 88% of ransomware payloads were deployed during non-business hours (evenings, weekends, and holidays), and 67% of all investigated incidents were rooted in identity-based attacks — meaning the attackers got in through a compromised account, not a sophisticated exploit.
How to Protect Your Business
Tested, isolated backups are the difference between a ransomware incident and a ransomware crisis. Businesses with working backup and disaster recovery systems are overwhelmingly the ones that do not pay the ransom. Beyond backups, phishing-resistant multi-factor authentication (MFA), endpoint detection and response (EDR), and 24/7 monitoring are foundational defences. If your business lacks the internal team to provide after-hours coverage — when 88% of attacks happen — a managed IT provider with round-the-clock monitoring is not optional; it is necessary.
2. Phishing and Social Engineering
Phishing remains the most common method attackers use to breach Canadian businesses. According to Statistics Canada's 2024 Canadian Survey of Cyber Security and Cybercrime, 88% of Canadian businesses experienced at least one phishing attempt in the 2024–2025 period, and 29% of those attempts were successful.
What Has Changed in 2026
Phishing in 2026 does not look like the poorly written emails of a decade ago. AI-generated phishing messages are grammatically flawless, reference real projects and people within your organization, and create urgency around tax deadlines, invoice payments, or HR policy changes. CRA impersonation emails alone accounted for thousands of successful attacks during the 2025 tax season across Canada.
The most dangerous evolution is adversary-in-the-middle (AiTM) phishing. The Canadian Centre for Cyber Security reported that it detected more than 100 AiTM phishing campaigns targeting Canadian Microsoft 365 tenants between 2023 and early 2025. These attacks operate a real-time reverse proxy of a legitimate login page (typically Microsoft 365 or Google Workspace). When the victim enters credentials and approves the MFA prompt, the proxy captures the authenticated session cookie, giving the attacker full access — completely bypassing traditional MFA.
In April 2026, a single coordinated AiTM phishing campaign hit more than 35,000 users across 13,000 organizations in 26 countries (Microsoft Threat Intelligence). The lures used HR-disciplinary themes designed to create panic and urgency.
How to Protect Your Business
Move to phishing-resistant MFA — FIDO2 security keys and passkeys — as a hard requirement, not an option. Both Microsoft 365 Business Premium and Google Workspace support passkeys natively. Layer this with advanced email filtering, regular employee security awareness training, and DNS filtering to block malicious domains before employees can click. At NetFusion Designs, we deploy six layers of cybersecurity protection as standard across all client environments, including email security that catches phishing attempts before they reach inboxes.
3. Business Email Compromise (BEC)
BEC does not generate the same headlines as ransomware, but it often causes greater financial damage to individual Canadian businesses. A BEC attack works when an attacker gains access to a legitimate email account (usually through phishing), monitors internal communications for days or weeks, then impersonates a trusted person to redirect a wire transfer, payroll deposit, or vendor payment.
A Threat Designed for Canadian Businesses
In April 2026, Microsoft Threat Intelligence published a case study on Storm-2755, a financially motivated threat actor whose victim-selection criterion is specifically "Canadian." The attack chain uses malvertising and SEO poisoning to drive Canadian employees to AiTM phishing pages. Once the attacker captures the session token, they log into the victim's Workday account and rewrite their salary deposit information — routing paycheques directly to the attacker's account.
Spear phishing and BEC accounted for $67.3 million in reported losses to the Canadian Anti-Fraud Centre in recent years. The true figure is almost certainly much higher, given that the CAFC estimates only 5–10% of victims report fraud.
How to Protect Your Business
Implement verification procedures for any financial transaction request — especially changes to banking details, wire transfers, and payroll modifications. Use out-of-band verification (a phone call to a known number, not a reply to the email) before approving any payment change. Deploy email authentication protocols (DMARC, DKIM, SPF) and ensure your managed cybersecurity provider monitors for mailbox rule changes and unusual login activity that indicate a compromised account.
4. Identity-Based Attacks and Credential Theft
The single largest shift in Canadian cybersecurity trends over the past 18 months is that identity is now the primary attack surface. Sophos's 2026 State of Identity Security survey found that 71% of organizations suffered at least one identity-related breach in the past year, and 67% of ransomware victims confirmed their incident stemmed from an identity attack.
Attackers are not breaking down the door with technical exploits — they are logging in with stolen credentials. CrowdStrike's 2026 Global Threat Report measured the average eCrime breakout time (the time from initial access to lateral movement) at just 29 minutes, with the fastest observed at 27 seconds. Mandiant's M-Trends 2026 reports that the median time between initial access and handoff to a secondary threat group fell to 22 seconds in 2025, down from more than eight hours in 2022.
No human-paced response process fits inside that window. Detection must be automated, or it is absent.
How to Protect Your Business
Implement phishing-resistant MFA on every account, with priority on administrative, financial, and executive accounts. Conduct quarterly access reviews to remove dormant accounts and unnecessary permissions. Deploy identity threat detection and response (ITDR) tools that monitor for anomalous login patterns, impossible travel scenarios, and session token replay. If your business uses Microsoft 365, consider upgrading to E5 licensing or partnering with an MSP that provides advanced threat monitoring to gain Entra ID Identity Protection capabilities.
5. AI-Powered Cyber Attacks
The Canadian Centre for Cyber Security assessed in its NCTA 2025–2026 that cybercriminals are using artificial intelligence to enhance their capabilities — and the trend is accelerating. AI does not create fundamentally new attack types; it makes existing attacks faster, cheaper, harder to detect, and easier to scale.
AI-generated phishing emails eliminate the grammatical errors that used to serve as warning signs. Deepfake audio and video are being used in CEO-impersonation calls to authorize fraudulent wire transfers. Large language models allow attackers to generate personalized spear-phishing messages at scale, tailoring lures to individual employees based on publicly available LinkedIn profiles and social media data.
IBM's 2025 data found that unsanctioned AI tools used within the workplace added approximately CA$308,000 to the total cost of a data breach. The risk is not just from external attackers using AI — it is also from employees using unapproved AI tools that inadvertently expose sensitive business data.
How to Protect Your Business
Establish a clear AI-use policy for your organization. Conduct security awareness training that includes AI-generated phishing examples. Deploy email security tools with AI-powered analysis that can detect the subtle patterns in machine-generated messages. For responsible AI adoption in your business operations, consider working with a provider that offers AI transformation guidance alongside security controls, so your team benefits from AI without introducing new risks.
6. Supply Chain and Third-Party Attacks
Your cybersecurity posture is only as strong as the weakest link in your supply chain. If your accounting software provider is breached, your financial data is exposed. If your IT vendor's remote management tool is compromised, attackers have a direct path into your network.
The Canadian Centre for Cyber Security's NCTA 2025–2026 specifically names managed service providers, software vendors, and professional services firms as part of Canada's critical supply chain — making them high-value targets. The CDW Canada 2026 Cybersecurity Study identified persistent execution gaps in supplier risk management among Canadian enterprises, noting that while board-level confidence is rising, foundational disciplines around third-party risk are not advancing at the same pace.
How to Protect Your Business
Ask every vendor and supplier that has access to your network or data: Are you SOC 2 certified? Where is our data stored? What happens if your systems are breached? At NetFusion Designs, we hold SOC 2 certification — one of the few MSPs in Ontario to do so — because we believe the organizations protecting your IT should be held to independently verified security standards. Your MSP, cloud provider, and critical software vendors should all be able to demonstrate documented security controls. If they cannot, that is a risk to your business.
7. Cloud Misconfigurations and Cloud Security Gaps
The shift to cloud infrastructure has transformed how Canadian businesses operate, but it has also introduced a category of risk that did not exist a decade ago. Cloud misconfigurations — improperly set permissions, publicly accessible storage buckets, unencrypted databases, and default credentials left unchanged — are now a leading cause of data breaches.
The CDW Canada 2026 Cybersecurity Study identifies cloud misconfigurations alongside ransomware and credential abuse as the convergent risks that compound in hybrid, cloud-first environments. The challenge for many Canadian SMBs is that cloud security operates under a shared responsibility model: your cloud provider (Microsoft, AWS, Google) secures the infrastructure, but you are responsible for configuring it correctly and managing access.
How to Protect Your Business
If you have migrated to the cloud (or are planning to), ensure your provider or managed IT partner conducts regular cloud configuration audits. Enable logging and monitoring across all cloud services. Enforce least-privilege access — give employees access only to the data and systems they need for their specific role. If your team uses Microsoft 365, ensure Conditional Access policies, data loss prevention (DLP) rules, and external sharing restrictions are properly configured. For businesses running cloud desktop environments, endpoint security must extend to every device accessing the cloud.
8. Insider Threats
Not every cybersecurity threat comes from outside your organization. Insider threats — whether from malicious employees, negligent staff, or compromised accounts — account for a significant portion of data breaches across Canada.
The risk is particularly high during employee transitions. A departing employee with access to customer records, financial data, or proprietary systems can cause significant damage — whether intentional or accidental. Statistics Canada data shows that 31% of Canadian businesses impacted by a cyber incident in 2023 identified identity theft as the method, up 11 percentage points from 2021, and a portion of these incidents originate from within the organization.
How to Protect Your Business
Implement role-based access controls and review permissions quarterly. Establish a formal onboarding and offboarding process that includes immediate access revocation for departing employees. Deploy user behaviour analytics (UBA) that flag unusual data access patterns, bulk file downloads, or after-hours activity. At NetFusion Designs, secure employee onboarding and offboarding is a standard part of our managed IT services, ensuring that new employees get the access they need — and departing employees lose it — on day one.
9. Regulatory Non-Compliance and Privacy Breaches
Cybersecurity compliance in Canada is not optional — it is a legal obligation. And the regulatory landscape is getting stricter.
PIPEDA (Personal Information Protection and Electronic Documents Act) requires every private-sector organization handling personal data for commercial activity to report breaches that pose a real risk of significant harm to the Office of the Privacy Commissioner. Penalties for knowingly failing to report reach up to CA$100,000 per violation. In the 2023–2024 fiscal year, the OPC received 693 breach reports from private-sector organizations, affecting approximately 25 million Canadian accounts.
Quebec Law 25 (Bill 64) has been in full force since September 2024 and applies to any organization handling data of Quebec residents, regardless of where the business is headquartered. It imposes a 72-hour breach notification window and penalties of up to CA$25 million or 4% of worldwide turnover — whichever is greater.
PHIPA (Ontario's health privacy law) applies to healthcare providers, clinics, dental offices, and pharmacies across Ontario. PCI-DSS applies to any business accepting credit card payments. And Bill C-8, the proposed federal cybersecurity statute, is advancing through Parliament and would expand baseline cybersecurity requirements for designated critical-systems sectors.
How to Protect Your Business
Compliance is not a one-time checkbox — it is an ongoing operational requirement. Your managed IT provider should be able to demonstrate compliance controls for the specific regulations that apply to your industry. This means documented privacy policies, breach response runbooks, encryption standards, audit logging, and access controls. At NetFusion Designs, our compliance management services cover PIPEDA, PHIPA, PCI-DSS, and SOC 2 readiness — with documentation that stands up to regulatory scrutiny.
If your business operates in healthcare, we offer specialized healthcare IT services with PHIPA compliance built in. For dental clinics, legal firms, and financial services organizations, we map our security controls directly to the compliance frameworks that apply to your industry.
10. Unpatched Systems and Legacy Infrastructure
Unpatched internet-facing systems — VPN appliances, remote desktop gateways, email servers, and firewalls running outdated firmware — remain one of the most common entry points for attackers targeting Canadian businesses. The modern intrusion rarely starts with a dramatic exploit. It starts with a known vulnerability that was publicly disclosed months ago but never patched.
The Canadian Centre for Cyber Security's core guidance is blunt: patch regularly, turn on multi-factor authentication, and keep tested backups. Yet Statistics Canada data shows that many Canadian SMBs still lack formal patch management processes.
Legacy systems that cannot be patched or upgraded pose an even greater risk. End-of-life operating systems, unsupported applications, and aging network hardware create permanent security gaps that no amount of perimeter defence can close.
How to Protect Your Business
Establish a formal patch management process that prioritizes critical and internet-facing systems. Maintain an asset inventory so you know exactly what is on your network — you cannot patch what you do not know exists. Plan a lifecycle replacement schedule for hardware and software approaching end-of-life. If your business depends on legacy applications that cannot be upgraded, segment them from the rest of your network and apply compensating controls. A virtual CIO can help you build a technology roadmap that phases out legacy risk while managing your budget.
What Canadian Businesses Should Do Now
The cybersecurity threats facing Canadian businesses in 2026 share a common theme: they exploit basic gaps. Stolen credentials, unpatched systems, missing MFA, untested backups, untrained employees, and unverified vendors. The most sophisticated attack campaigns in Canada right now — Storm-2755, AiTM phishing, Akira ransomware — all begin with one of these fundamental failures.
The good news is that basic discipline blocks the majority of intrusions. Here is where to start:
Get a security assessment. You cannot fix what you have not measured. A penetration test and vulnerability assessment identifies the specific weaknesses in your environment before attackers find them.
Deploy phishing-resistant MFA everywhere. Traditional SMS-based MFA is no longer sufficient. FIDO2 passkeys and security keys block more than 99% of identity-based attacks (Microsoft).
Test your backups. Having backups is not enough — you must test recovery regularly. A comprehensive backup and disaster recovery plan should be verified quarterly at minimum.
Train your people. Your employees are both your greatest vulnerability and your strongest defence. Regular security awareness training that reflects current threats — including AI-generated phishing — is essential.
Partner with a certified MSP. If your business lacks a dedicated security team (most Canadian SMBs do), a SOC 2 certified managed service provider delivers 24/7 monitoring, incident response, and compliance support at a fraction of the cost of building those capabilities in-house.
At NetFusion Designs, we serve businesses across Kitchener-Waterloo, Toronto, Markham, Mississauga, the Greater Toronto Area, Montreal, Winnipeg, and across Canada with managed cybersecurity services built on six layers of protection, 24/7 monitoring, under-30-second call response, and 90% same-day issue resolution. We are SOC 2 certified, we do not lock clients into long-term contracts, and we offer a free first month for qualifying businesses.
