In 2025, Canada's healthcare system faces an unprecedented wave of cyber threats targeting hospitals, clinics, and critical health infrastructure. These attacks pose serious risks not only to operations but also to patient privacy and trust.
Earlier this year, Toronto General Hospital experienced a massive ransomware attack that crippled its digital systems for nearly 48 hours. Patient files were inaccessible, surgeries delayed, and the hospital forced to revert to paper records.
Similar incidents were reported in Vancouver, Calgary, and Halifax, with attackers demanding payment in cryptocurrency and threatening to leak sensitive medical data unless their demands were met.
“We are now seeing weekly attempts to breach our systems,” said Dr. Angela Murray, CIO of a major Ontario health network. “It’s become a constant digital battle.”
Healthcare institutions hold vast amounts of sensitive data: medical histories, personal IDs, billing information — all highly valuable on the dark web. But many Canadian hospitals still rely on outdated IT infrastructure and underfunded security frameworks.
Cybercriminals exploit this digital vulnerability using phishing, malware, and advanced social engineering tactics.
In response, the federal government has pledged an additional $250 million over three years to bolster cybersecurity across provincial health services. This includes real-time threat detection systems, staff training, and partnerships with cybersecurity firms.
Provinces like Quebec and British Columbia are piloting AI-powered monitoring platforms to detect and isolate threats before damage can occur.
Beyond technical damage, cyberattacks erode patient trust. A recent survey by Ipsos found that 62% of Canadians are now worried their health data could be compromised during medical visits.
Privacy advocates are calling for new national standards and better breach notification laws to ensure transparency and accountability.

Delayed care due to a cyberattack can have real-world consequences.”
As attacks grow more complex, investment in resilient systems and ongoing vigilance will be key to keeping Canada's healthcare safe.
