Thanks for the responses. The fare is $423 CAD; it’s with Jet from YYZ to AMS, and with KLM from AMS to VCE. Unfortunately, the only booking option I have found is with Jet directly. The next lowest fares are almost double.

I am not committed to this itinerary, so if the ticket is cancelled it wouldn’t be a big deal. But I don’t want to bother even trying if it’s highly unlikely to be honoured.
