The Landmark CMAJ Study Exposing Canada's EHR Disconnect
A groundbreaking study published on May 4, 2026, in the Canadian Medical Association Journal (CMAJ) has laid bare a persistent crisis in Canada's digital health landscape. Led by researchers from the University of Calgary's Cumming School of Medicine, the report titled "The current state of electronic health records across Canada: an environmental scan and interoperability maturity assessment" reveals that while electronic health records (EHRs)—comprehensive digital versions of patients' paper charts containing medical history, diagnoses, medications, and test results—are nearly universally adopted, their ability to seamlessly share data across systems is woefully inadequate. This lack of interoperability, defined as the secure exchange and effective use of health information between different EHR platforms, providers, and settings, is not just an inefficiency; it's actively harming patients and straining the healthcare system.
The study, authored by Sunand Kannappan, Stephanie Hastings, and senior investigator Dr. Braden Manns, along with collaborators from institutions like McGill University and Canada Health Infoway, analyzed all 10 provinces and 3 territories. Using a newly developed maturity model assessing governance, legislation, incentives, technical infrastructure, and practical status like community and hospital EHR exchange, patient portals, and analytics, the findings are stark: no jurisdiction excels across the board, and data sharing remains primitive.
High Adoption Meets Low Connectivity: The Paradox at Canada's Core
Canada has invested billions through Canada Health Infoway and provincial programs since the early 2000s, achieving remarkable EHR adoption rates. Over 95% of physicians now use EHRs or electronic medical records (EMRs), up from just 36% in 2009. Hospitals boast over 90% adoption in most provinces, with community clinics similarly digitized. Yet, this digital transformation has failed to deliver connected care. Information exchange between primary care physicians, specialists, hospitals, pharmacies, and labs predominantly relies on fax machines—traditional paper faxes or digital "efaxes"—or even mailed letters. Only select areas like Saskatchewan and Prince Edward Island show meaningful electronic sharing.
The researchers' environmental scan, drawing from Infoway surveys and interviews with 23 experts from September 2024 to June 2025, highlights a fragmented patchwork. Large provinces like Ontario, British Columbia, and Quebec suffer from dozens of incompatible vendor systems, while smaller ones like PEI and territories leverage single-platform approaches with better results. Patient portals exist province-wide in many areas but offer limited content, with national access to electronic personal health information hovering at 47%, ranging from 18% in territories to 72% in Saskatchewan.
Provincial Disparities: Leaders, Laggards, and the Scorecard
The study's innovative Connected Care Scorecard, an interactive tool visualizing maturity levels, underscores stark regional variations. Atlantic provinces and territories shine in governance and incentives—advanced ratings for accountable oversight and training programs—while larger provinces lag at basic or emerging levels. Legislation and standards are advanced only in Manitoba and PEI, where mandates enforce common protocols. Technical infrastructure varies, strongest where robust shared repositories capture discharge summaries, labs, imaging, immunizations, and medications.
For practical use, community EHRs are advanced nationwide for basic functionality but basic for inter-practice exchange. Hospital systems show emerging interoperability, except in Alberta and PEI. System analytics from EHR data remain rudimentary everywhere, blocking population health insights and AI applications. Smaller jurisdictions often outperform giants, proving scale isn't destiny—strong planning is.
- Standouts: PEI (advanced hospital exchange, legislation), Nunavut (incentives), Saskatchewan (sharing).
- Challenges: Ontario/BC (fragmented vendors), Quebec (lower adoption).
- Territories: Varied, with Yukon/Alberta-like single hospital EHRs but clinic gaps.
Patient Harms: The Human Cost of Siloed Data
When EHRs don't talk, patients suffer. Clinicians lack complete histories, leading to duplicated tests, missed allergies, overlooked drug interactions, diagnostic delays, and unsafe prescribing. Broader data indicates 1 in 18 hospitalized Canadians experiences preventable harm, much tied to information gaps. In one example from British Columbia, a patient treated in Vancouver ER must retell their story and repeat tests in nearby Burnaby due to incompatible systems—a scenario repeated nationwide.
Sunand Kannappan notes, "When records are disconnected, clinicians do not have the full picture. That can really harm patients." Dr. Manns adds it's "leaving patients’ health records fragmented... harming patients." Low patient portal use exacerbates this; patients carry printed summaries, delaying care during transitions like hospital discharges to primary care. Explore the full CMAJ study details here.
Clinician Overload: Faxes, Burnout, and Lost Time
Physicians spend hours weekly hunting records, rekeying data, and faxing, fueling burnout amid administrative burdens cited by nearly 60% as harming mental health. Only 29% share clinical summaries electronically outside practices, per recent surveys. Dr. Fahad Razak calls it "unacceptable disconnectedness," with safety events and distress normalized. Black Book Research confirms 73% view poor integration as a top barrier.

A Staggering Economic Toll: $9.4 Billion Annually
Fragmentation squanders public funds. The study cites a 2025 analysis estimating over $9.4 billion yearly in taxpayer costs from unwarranted tests, inefficiencies, and missed savings. Provincial investments yield silos, not synergy, blocking analytics for planning and AI-driven efficiencies. Transforming data systems could unlock billions, per health economists.
Unpacking the Eight Barriers to Progress
The researchers pinpoint eight surmountable obstacles:
- Weak governance without oversight.
- No interoperability laws mandating sharing.
- Misaligned incentives ignoring data exchange value.
- Technical/funding shortfalls for unified platforms.
- Clinician digital literacy gaps and change resistance.
- Privacy fears prompting access restrictions.
- Vendor data-blocking via proprietary tech and fees.
- Inconsistent data standards/workflows.
A companion Connected Care Scorecard tracks fixes.
Government Response: Bill S-5 Lights the Way
Federal action ramps up. Bill S-5, the Connected Care for Canadians Act, reintroduced February 4, 2026, mandates common standards, bans data-blocking, and accelerates Infoway's roadmap. Health Minister Marjorie Michel states it empowers patients with secure access, cutting faxes. Provinces must align or face federal rules, promising portability like Taiwan's seamless updates.
Infoway's Roadmap and Provincial Momentum
Canada Health Infoway drives standards via Projectathons and dashboards tracking access trends. Provinces modernize: Alberta/PEI advance repositories; Ontario eyes FHIR APIs. Black Book notes procurement gates emphasizing conformance amid cyber risks.
Global Lessons: Taiwan and Denmark Lead
Taiwan integrates vendor-diverse EHRs for auto-updates; Denmark's unified platforms enable analytics. Canada can emulate with mandates, incentives, and vendor-neutral policies.
Towards Connected Care: Actionable Steps Forward
Overcome barriers via legislation like S-5, Infoway incentives, clinician training, cybersecurity trust, vendor innovation. Prioritize repositories, portals, analytics. Patients gain control; clinicians efficiency; systems savings. UCalgary's work spotlights urgency—Canada's digital health future hinges on connectivity.
Stakeholders urge: harmonize standards, fund transitions, measure via Scorecard. With momentum, 2026 could mark the pivot from silos to synergy, safeguarding patients and unlocking potential.
