During a precautionary landing in Canada, would the Montreal Convention apply if an accident occurs?

The relevance of the Montreal Convention in this scenario depends critically on whether the flight in question is considered international or domestic. The Montreal Convention, which governs liability in international air transport, applies primarily to flights that cross international borders. If all passengers are ticketed for domestic travel, then the situation falls under domestic aviation laws rather than international treaties.

In this case, since the precautionary landing occurs in Canada with all passengers ticketed for domestic travel, the legal framework provided by the Montreal Convention is not applicable. Domestic incidents are governed by national laws and regulations specific to Canada, meaning that any accidents during this precautionary landing wouldn't invoke the protections or liabilities outlined in the Montreal Convention.

Therefore, the correct understanding is that the Convention applies only to international flights, making the assertion that the Montreal Convention does not apply due to the nature of the tickets issued accurate. The other options suggest situations that would misapply the Convention to a domestic context, reinforcing the specificity of jurisdiction that governs aviation law.
