Canada’s cyber threat landscape is changing fast. Gone are the days when a simple antivirus and occasional patching would keep a small or medium business safe.
Today’s attackers are more organized, better resourced, increasingly creative, and their targets now include not only big enterprises and government bodies, but also small service providers, supply-chain partners and single-site businesses.
If you run a Canadian business, understanding the emerging threats and taking practical steps to reduce risk isn’t optional, it’s a business imperative.
What’s changed, and why it matters
Several forces are reshaping cyber risk:
- Ransomware has become weaponized. Attackers now combine encryption with data theft, double extortion, and prolonged extortion campaigns that go after backup systems and business partners. Ransomware remains the top cybercrime threat to Canadian critical infrastructure and many private organizations.
- AI is a force-multiplier for attackers. Generative AI tools make phishing and social-engineering far more convincing, often creating personalized messages, voice deepfakes, or even fake documents that closely mimic real communications. These tools lower the cost and raise the scale of targeted attacks.
- Supply-chain and third-party risks are front-and-centre. Organizations increasingly rely on external software and managed services, and attackers exploit weak links in the chain to reach many victims from one compromise (think SolarWinds as the archetype). Managing vendor risk is no longer optional.
- Regulation and privacy law are tightening. Bill C-27, which introduces the Consumer Privacy Protection Act and the Artificial Intelligence and Data Act, brings new obligations for handling personal data and for AI-driven systems. Failing to meet compliance expectations can mean steep fines, reputational damage and mandatory incident reporting.
These trends mean attacks are faster, cheaper for criminals to carry out, and more damaging when they succeed. But they also point to practical, proven defences businesses can adopt.
The Top Emerging Threats Canadian Businesses Need to Watch
1. Ransomware and double extortion
Ransomware groups now routinely steal data before encrypting systems, then demand two ransoms: one for a decryptor and another (or separate publication extortion) to stop leaking data. Critical infrastructure and healthcare remain prime targets because of the immediate pressure to restore services. In Canada, government and security agencies continue to warn that ransomware will be a persistent and escalating threat for the next several years.
What to do: maintain immutable backups, segment networks so infections can’t spread laterally, enforce least privilege access, and practice incident response tabletop exercises. Don’t negotiate solo. Coordinate with legal counsel and relevant government agencies if hit.
2. AI-assisted phishing and deepfakes
Phishing is evolving. Attackers use generative AI to craft highly personalized emails, produce convincing voice deepfakes for executive impersonation and even generate fake documents or websites that are difficult to distinguish from the real thing. Reports show rising use of these techniques and increased success rates.
What to do: adopt multi-factor authentication (MFA) everywhere, run frequent simulated phishing campaigns, educate staff about AI-driven scams, validate requests for financial or sensitive information through separate channels (phone calls using trusted numbers), and lock down privileged accounts.
3. Supply-chain and third-party compromise
An attacker only needs one trusted vendor to gain a foothold inside many victims. Software updates, managed service providers, and third-party integrations are frequent vectors.
What to do: inventory your third-party relationships, require security attestations from critical vendors, restrict vendor access with the minimum privileges necessary, and monitor for unusual behaviours originating from trusted integrations.
4. Targeting of operational technology (OT) and critical infrastructure
Industries that combine IT and operational technology, utilities, manufacturing, transportation, and healthcare, face higher stakes because cyberattacks can cause physical disruption. Canadian agencies flag ransomware and disruptive intrusions as key risks to critical services.
What to do: separate OT networks from corporate IT, apply compensating controls for legacy systems that can’t be patched, run regular security audits of ICS/SCADA components, and establish rapid coordination plans with suppliers and regulators.
5. Increased targeting of small and medium businesses
Smaller organizations are no longer off the radar. They are easier prey, and attackers know that many SMBs act as gateways to larger customers or supply chains. Surveys indicate a meaningful share of Canadian organizations experienced ransomware or phishing incidents in recent years, and many paid to recover data.
What to do: apply basic cyber hygiene consistently (patching, MFA, backups), consider managed security services, and treat security as an operational priority rather than a one-off project.
Practical, High-Impact Steps Every Canadian Business Should Implement Now
The list below focuses on actions that give strong defensive returns without needing huge budgets.
- Start with the basics, and do them well. Patch management, endpoint protection, MFA, least privilege policies and reliable offline backups stop the majority of incidents. The Cyber Centre emphasizes that basic controls prevent most ransomware incidents.
- Adopt a Zero Trust mindset. Assume the network is hostile. Verify every user and device, segment systems, and restrict application permissions to what they actually need. Zero Trust materially reduces the blast radius of breaches and is especially useful against supply-chain and lateral-movement attacks.
- Protect identity and access. Treat identity as the new perimeter: institute strong password policies, MFA, and privileged access management (PAM). Monitoring for anomalous sign-ins and conditional access policies are high-value controls.
- Protect backups and test recovery. Backups are only useful if they are immutable, offline from primary systems, and tested regularly. A documented, practised recovery plan halves recovery time and reduces costly mistakes during an incident.
- Train people, but test them too. Ongoing awareness training plus simulated phishing helps staff spot sophisticated AI-assisted scams. Role-specific training (finance, HR, executives) is particularly effective.
- Map and manage third-party risk. Know which vendors have access to your systems and data, what controls they use, and require incident notification clauses in contracts. Prioritize controls for vendors that have privileged access to sensitive systems.
- Plan for incident response and reporting. Have an incident response plan that includes communications, legal counsel, cyber insurance coordination, restoration priorities and an escalation path to law enforcement and the Canadian Centre for Cyber Security when required.
Compliance and Legal Landscape — What’s New in Canada
Canada’s regulatory environment is evolving. Bill C-27 (the Digital Charter Implementation Act) introduces the Consumer Privacy Protection Act (CPPA) and the Artificial Intelligence and Data Act (AIDA).
These changes elevate expectations for privacy protection, data stewardship and the safe use of AI. Businesses handling personal information or deploying AI systems should take note, non-compliance can lead to hefty penalties and mandatory public disclosures.
If your organization operates in regulated sectors (healthcare, finance, critical infrastructure) you may face additional sectoral reporting obligations and security standards. Staying ahead of compliance reduces legal and reputational risk after an incident.
Incident Preparedness
The organizations that recover quickly from a breach are those that had prepared long before the incident:
- Clear playbooks and decision trees for containment, eradication and recovery.
- Pre-identified external partners (forensics, legal, PR) and cyber insurance contacts.
- Regular tabletop exercises that stress tested communications and recovery steps.
Practicing for a breach is also resilience planning. It shortens downtime, reduces ransom pressure, and helps maintain customer trust.
Why Managed Security Can Make Sense for Canadian Businesses
Many organizations find it challenging to build and maintain specialist security capability in-house.
Managed Security Service Providers (MSSPs) or virtual Chief Information Security Officers (vCISOs) give access to expertise, 24/7 monitoring, threat intelligence and tested incident response playbooks, often at a fraction of the cost of hiring full-time specialists. For Canadian businesses facing sophisticated, AI-enabled threats, partnering with experienced security providers is now a mainstream defence choice.
Final Thoughts: Make Security a Business Conversation
Cybersecurity is not only an IT problem. It’s a business risk that affects finance, operations, legal, HR and the boardroom. The most resilient organizations treat cyber risk as part of enterprise risk management: they measure it, prioritize it, fund it and practise responses.
Start with the basics and build from there: patching, MFA, immutable backups, vendor risk management, and incident planning will reduce the chance of being a headline. Then layer in advanced monitoring, Zero Trust controls and AI-aware defences as you scale.
