What should I do for a cancelled flight involving YSB?
Under Canada's APPR, a cancellation can trigger rerouting or refund rights, and sometimes assistance or inconvenience compensation. The cause, operating airline size, notification timing and replacement arrangements matter. Cancellation alone does not establish an automatic payout.
This guide is not a report that a disruption occurred today at YSB. Verify the actual flight and itinerary with the operating airline. An airport identifier does not decide personal eligibility.
Check your airport record: YSB / CYSB
The airport recorded as Greater Sudbury Airport serves Greater Sudbury in Ontario, Canada. Its IATA code is YSB and its ICAO identifier is CYSB. Compare both against airline booking documents so a similarly named airport or a changed departure airport does not lead you to the wrong claim.

Decide between replacement travel and refund
- Original booking: save the exact YSB segment, airline, booking reference and original departure/arrival times.
- Cancellation notice: record when the operating airline notified you, its reason and any replacement flight proposed.
- Your decision: preserve whether you accepted rerouting or declined it and requested a refund. These choices can change the remedy.
- Claim evidence: retain any unused-ticket, refund and incidental-expense records and confirm the appropriate national regulator.
Canadian APPR: record cause, notice, rerouting and care facts before assessing compensation or refund rights.
