Very nice, unbiased, balanced statements. First, this is a thread about current border controls and when Air Canada may or may not resume flying certain routes. Don't drag Covid-19 vaccine opinions into this thread. There is a separate thread for that. Please use it.
Also in every thread you get a chance, you refer to the compulsory border quarantine as "jail". Another "unbiased" and inaccurate statement. You can avoid it by simply not travelling outside the country. Your choice. No one is forcing you.. If you think being isolated in a 2- to 4-star hotel for 3 days minimum is anything like being in a jail, then I suggest you go visit a real jail first. They are not at all alike.
Finally Air Canada and WestJet are commercial enterprises. They normally only fly if they can make a profit. With the current travel restrictions in place, there are very few, if any, travellers to occupy those aircraft, even without any "agreement". They were cancelling all sorts of flights last year when there weren't enough bookings to justify a flight, including our trip to St. Martin in January and many more before that. Simple math, not a Q-Anon conspiracy theory.
I'm sorry that your travel plans have been disrupted. So have mine. Build a bridge and get over it, or find something more constructive to do.
