Flight delayed by a mechanical problem: are you owed compensation in Canada?

Updated September 27, 2026 · Checked against the regulations as current to September 3, 2026 · By LandedLate

Sometimes. Under Canada's Air Passenger Protection Regulations, an unexpected mechanical fault is usually treated as within the airline's control but required for safety, so no compensation is owed. But a problem found during scheduled maintenance, or one the airline caused through poor maintenance, is within its control, and a large airline then owes $400 to $1,000 per passenger for arriving 3 or more hours late. When a fault is required for safety, you're still owed food and drink after a 2-hour wait and a hotel overnight if you were told less than 12 hours ahead, and a new flight or a refund once the delay reaches 3 hours. Rules as of September 27, 2026.

How the fault was found decides the category

The problem	Category	Compensation
Found during scheduled maintenance	Within the airline's control	Owed
Caused by the airline's own poor maintenance	Within the airline's control (Anslow v. Sunwing)	Owed
Another plane's fault, and your plane was moved to cover it	Within the airline's control (Lubky v. WestJet)	Owed
Unexpected, or found in a pre-flight check	Within its control but required for safety	Not owed, unless the airline could have avoided it
A manufacturing defect flagged by the manufacturer or a regulator	Outside the airline's control (section 10(1)(k))	Not owed

Sections 1, 10 and 11 of the regulations, and the Canadian Transportation Agency's guide to types and categories of flight disruption.

Rulings on mechanical claims

Case	What happened	Result
Anslow v. Sunwing, 20-C-A-2023	Frozen, ruptured lavatory pipes forced an aircraft change on a return flight from Cancun. The agency found freezing was foreseeable in a Regina winter and the delay could have been prevented if the maintenance and ground crew had been prudent and diligent.	$400 each
Lubky v. WestJet, 137-C-A-2022	WestJet used the plane scheduled for a Honolulu flight to rescue passengers from another plane with a fuel-tank problem. The other plane's fault wasn't a direct cause of the cancellation.	$1,000 each

The court test behind a safety label

In WestJet v. Lareau (2025 FCA 149), a crew case, the Federal Court of Appeal upheld the agency's approach: a disruption within the airline's control is required for safety only if the airline took reasonable measures to avoid the risk and followed a reasonable contingency plan. Passengers cite it by analogy against other safety labels, including mechanical ones.

When a mechanical delay is worth challenging

Likely owed

The problem came from scheduled maintenance or poor upkeep, or your plane was moved to cover another flight.

Worth challenging

The airline only says “maintenance” or “safety”, the fault had been deferred on earlier flights, or it took hours to find a replacement plane.

Likely not owed

A genuine, unexpected fault found before departure, which the airline fixed or worked around quickly.

What to ask the airline for

the specific defect, and on which aircraft;
when and how it was found (scheduled maintenance, a pre-flight check, or in flight);
the maintenance log entries for it, including whether it was reported or deferred on earlier flights;
whether the aircraft scheduled for your flight was replaced or moved, and why.

The airline has 30 days to pay or explain (section 19(4)), and a general reference to safety isn't an explanation of which category applies.

Questions

Is a mechanical problem a safety issue?

Often, but not always. The regulations define a mechanical malfunction as a problem that reduces passenger safety, excluding problems found during scheduled maintenance (section 1). The Canadian Transportation Agency treats unexpected malfunctions not identified in routine maintenance as within the airline's control but required for safety, and problems found in scheduled maintenance as within its control.

What if the problem was found during the pre-flight check?

The agency's guide says pre- and post-flight checks aren't scheduled maintenance, and problems they find are generally within the airline's control but required for safety. That usually means no compensation, unless the airline caused the problem or didn't take reasonable steps to avoid it.

What am I owed if the mechanical problem was required for safety?

No compensation, but the airline must keep you informed, give you food, drink and a hotel if you were told less than 12 hours before departure, and offer a new flight or a refund once the delay reaches 3 hours (section 11).

What about a manufacturing defect or a grounding?

A manufacturing defect that reduces passenger safety and was identified by the aircraft's manufacturer or a competent authority is outside the airline's control (section 10(1)(k)). No compensation or meals are owed, only rebooking or a refund.

Is this changing?

Proposed amendments published in December 2024 would remove the separate "required for safety" category and excuse compensation only for listed exceptional circumstances. One of them is an unforeseeable technical defect, but only if scheduled maintenance was up to date, the defect was found after the last required maintenance, the pilot judged the aircraft unsafe to fly, and the airline didn't cause it. They weren't in force as of September 27, 2026.
