The Air Passenger Protection Regulations set out what Canadian air carriers owe passengers when a flight is delayed, cancelled or oversold — compensation tiers, rebooking duties, standards of treatment, and obligations to communicate the reason for a disruption and its status. Administered by the Canadian Transportation Agency and progressively tightened since taking effect in 2019.
Air Passenger Protection Regulations
Statute Canada
The APPR turned Canadian air passenger rights from airline policy into statutory obligation. Carriers owe compensation on a tier scale for controllable delays and cancellations, must rebook passengers within defined windows, must provide standards of treatment during disruption, and — the part that matters most here — must communicate the reason for a disruption and update the passenger as the status changes.
- Communication is a legal duty - carriers must state why a flight is disrupted and keep the passenger informed, on a defined cadence.
- Tiered by carrier size and cause - obligations differ between large and small carriers, and between controllable, controllable-for-safety and uncontrollable causes.
- Enforced by the CTA - complaint-driven, with a backlog that has been the subject of successive amendments.
An event obligation with no event contract
The State of Canadian Travel APIs scored nine organizations against this backdrop. Two of nine publish an event contract. Zero publish an idempotency mechanism — neither at full credit nor as anything API Evangelist could derive from the documentation.
The regulation compels carriers to track and communicate the state of a disruption. That is, structurally, an event stream: a flight changes status, and every downstream party — the passenger, the agency that sold the ticket, the corporate travel manager, the insurer — needs to know. Canadian carriers do that work today through email, SMS and app notifications aimed at humans.
Nothing in the APPR asks for a machine-readable version of the same information, and the market has not built one voluntarily. The two organizations that do publish event contracts are not the carriers under the heaviest obligation.
There is a second-order effect worth noting for diligence. A statutory compensation regime creates reconciliation work — claims, evidence, payment — and that work is exactly where a duplicated or lost request is expensive. Canada mandated the obligation and left the transaction-safety layer unspecified, which is the same shape as the UK Package Travel Regulations and ATOL.
Canada has, meanwhile, built a genuine data-portability framework next door in banking, through consumer-driven banking. Travel is not in scope for it, and no timetable suggests it will be.

Statutory compensation and communication duties for delays and cancellations, in a market where zero of nine organizations publish an idempotency mechanism and only two publish an event contract.
