I wasn't aware you were Canadian. I suddenly find myself thinking of my first (partially) Canadian vacation. (I don't do single-destination vacations; I like my vacations complicated.)
At any rate, it was during the first Trump Administration, pre-COVID, and I'd decided that just in case I found myself "no longer joking" about permanently locating to Winnipeg, I should probably at least spend a vacation in Canada, including a Winnipeg stay. And so, on the tail end of a vacation that also included San Francisco and Seattle, I hopped a bus to Vancouver, BC, spent the day at Science World (rather conveniently located a short walk from the train station), and then got on VIA Rail Canada's Canadian, in the cheapest sleeper accommodation they'd sell me.
I quickly found out that while VIA Rail Canada is somewhat more luxurious than Amtrak (the food they serve sleeping car passengers is particularly superb), it has one glaring problem, especially during the wheat harvest season: the trains, at least through the Prairie provinces, run late. So late, they make Amtrak's worst on-time performance seem like Deutsche Bahn.
That trip, I went from Vancouver to Toronto, with a 2 or 3 day layover in Winnipeg (The Canadian only runs 3 times a week, so if you want an intermediate stop, it's going to be more than a 24-hour layover), arriving in Toronto just in time for the traffic jams created by British royalty arriving to attend the Invictus Games (and missing a planned visit to their science museum). A year later, I flew to Toronto, saw the things I'd missed because of the late train, then went on to visit Quebec, New Brunswick, Nova Scotia, Prince Edward Island (by bus), and Newfoundland (by air). And so I've been to all 10 Provinces (I'd finished visiting all 50 States some years earlier).
My point, though, was that trains have nicer seats (though not as nice as they had a few years ago), with lots and lots of legroom, and you really can simply show up at the station, with ticket in hand, walk out to the platform, and get on board. It takes a lot longer than flying, but it's relaxing, and it's extremely energy-efficient.
