Canada recorded 352 ransomware cases in 2025, a 46% increase over 2024, according to data tracked by NordStellar and ransomware.live. For businesses operating in the Greater Toronto Area, that number carries weight far beyond the national average. Ontario accounts for more corporate headquarters, healthcare networks, and manufacturing hubs than any other province, making it the country’s largest concentration of high-value targets.
The surge is not slowing down. The Canadian Centre for Cyber Security (CCCS) projects ransomware incidents will climb another 40% by the end of 2026, per their Ransomware Threat Outlook 2025-2027. If your organization has not stress-tested its defences in the past 12 months, the window for preparation is shrinking fast.
The 352-case total for 2025 tells one story. The quarterly breakdown tells a sharper one. Q4 2025 alone accounted for 107 cases, a 73% spike from Q3 (NordStellar). That acceleration suggests attackers found new footholds late in the year and carried momentum into 2026.
Year-over-year, Canada has moved from a secondary target to a primary one. Ransomware operators now treat Canadian organizations as reliable payers. According to a 2025 Cybersecurity Canada Report, 74% of Canadian businesses that suffer a ransomware attack end up paying the ransom, with the average payment hovering around $25,000.
That payment statistic matters because it creates a feedback loop. Every ransom paid confirms to criminal groups that Canadian targets are worth the effort. The Q4 surge is a direct consequence of that reputation. When attackers compare the effort of breaching a mid-market firm in Ontario against the probability of receiving payment, the math works in their favour.
Ontario houses the highest concentration of mid-market businesses in Canada. Organizations with 51 to 200 employees absorb the most ransomware attacks nationally, according to the 2026 Cybersecurity Canada Report. These companies have enough data and revenue to justify an attack but often lack the dedicated security teams that larger enterprises maintain.
The GTA’s industry mix compounds the risk. Healthcare, financial services, manufacturing, and logistics all cluster in the region. Each sector depends on uptime, handles sensitive records, and faces regulatory pressure if breached.
Southern Ontario has already felt the impact directly. In October 2023, five hospitals were hit by a coordinated ransomware attack, disrupting patient care and diverting ambulances across the region (CCCS). The incident exposed how a single breach can cascade across interconnected healthcare networks, affecting patient outcomes and costing millions in recovery.
Proximity to U.S. supply chains adds another dimension. GTA-based manufacturers and logistics firms often hold credentials, order data, and network connections that link directly to American partners. Attackers know that compromising a Canadian supplier can open doors into larger U.S. organizations, making these businesses doubly attractive targets.
IBM’s 2025 Cost of a Data Breach Report puts the average cost of a data breach in Canada at CA$6.98 million, a 10.4% increase from CA$6.32 million in 2024. That figure includes detection, containment, notification, lost business, and regulatory fines.
The attack vector matters. Phishing, the most common initial entry point, drives breach costs to CA$7.91 million per incident (IBM 2025). Shadow AI, where employees use unauthorized AI tools that process company data outside approved channels, adds another CA$308,000 per breach.
Beyond the direct financial hit, there is the reputational damage. A breach triggers mandatory reporting under PIPEDA when there is a real risk of significant harm. That public disclosure can erode client trust, delay contracts, and invite scrutiny from the Office of the Privacy Commissioner.
For mid-market firms, a CA$6.98 million event can threaten the business itself. Unlike large enterprises with reserves and insurance policies sized for cyber events, a 150-person company in Mississauga or Markham may not survive the combination of recovery costs, legal fees, and lost revenue. Customer churn after a public breach compounds the damage over the 12 to 18 months following the incident.
Understanding entry vectors is the first step toward blocking them. The most common paths into Ontario businesses include:
Preparation does not require a massive budget. It requires discipline and consistency. The following six steps form a baseline that every mid-market organization in the GTA should have in place before the end of 2026.
A ransomware preparation strategy is only as strong as the team behind it. For many mid-market businesses, building a full internal security operation is not feasible. That is where a cybersecurity partner becomes essential.
The right partner covers the full incident lifecycle. Risk assessment identifies where your organization is exposed before an attack happens, mapping your vulnerabilities to the specific threats targeting your sector and region. Incident and breach response services ensure that when something does go wrong, your team has expert support within the first critical hours, when containment decisions determine whether you lose one system or one hundred. And recovery services get your systems back online with validated, clean restorations that confirm no attacker persistence remains.
Brigient operates from the GTA and works exclusively within Canadian regulatory frameworks. That matters because compliance obligations under PIPEDA, PHIPA, and the upcoming Bill C-26 require a partner who understands the specific reporting timelines, notification requirements, and documentation standards that apply to Ontario businesses.
A cybersecurity partner should also help you build internal capacity over time. That means training your staff, documenting your security controls, and creating governance structures that survive personnel changes. The goal is not permanent dependency. It is resilience.
How likely is a ransomware attack on a mid-sized Ontario business in 2026?
Very likely if your defences have not been updated recently. Organizations with 51 to 200 employees are the most targeted segment in Canada, according to the 2026 Cybersecurity Canada Report. The CCCS projects a 40% increase in ransomware incidents nationally by end of 2026. If you operate in healthcare, manufacturing, or professional services in the GTA, you fit the profile attackers are looking for.
Should we pay the ransom if we get hit?
Law enforcement agencies, including the RCMP and CCCS, advise against paying. Payment does not guarantee you will get your data back, and it funds future attacks. However, 74% of affected Canadian businesses do pay, which indicates many feel they have no other option. The better strategy is to invest in prevention and recovery capabilities now so you never face that decision.
What is the first thing we should do after detecting a ransomware incident?
Isolate the affected systems immediately to prevent lateral spread. Do not shut down machines, as forensic evidence on running systems can help identify the attack vector and scope of compromise. Activate your incident response plan, contact your cybersecurity partner and legal counsel, and begin assessing the scope. Under PIPEDA, you must report to the Office of the Privacy Commissioner if there is a real risk of significant harm to affected individuals.
How much does ransomware preparation cost compared to a breach?
A comprehensive security program for a mid-market business, including EDR, MFA, backups, training, and incident response planning, typically costs a small fraction of the CA$6.98 million average breach cost in Canada. Organizations that deploy security AI and automation reduce their breach costs to CA$5.19 million versus CA$8.53 million without such tools (IBM 2025). Prevention is always cheaper than recovery, and the return on investment is measurable.
Does cyber insurance cover ransomware?
Many policies do, but coverage terms have tightened significantly over the past two years. Insurers now require evidence of specific controls, including MFA, EDR, offline backups, and a documented incident response plan, before they will underwrite a policy. If your security posture does not meet their baseline, you may face denied claims or policy cancellations. Think of insurance as a complement to security, not a substitute for it.
The 46% surge in Canadian ransomware cases is not an abstract statistic. It reflects real attacks on real organizations, many of them in Ontario. The businesses that come through these incidents intact are the ones that prepared before the attack arrived.
If your organization has not reviewed its ransomware readiness in the past six months, start now. Assess your exposure, test your backups, train your people, and make sure you have a response plan that works under pressure.
Brigient helps GTA businesses build exactly that kind of preparedness, from initial risk assessment through incident response and recovery. Contact us to schedule a ransomware readiness assessment for your organization.
