Fyi, my fiancée became a Canadian resident a few years back. When you become a new resident Canada gives you a welcome package, in this package you get a one year voucher for free visits to any national park (ie, not provincial parks).
So the closest national park to us is like 6-7 hours away. We do the drive and have no way to use this voucher, even in the one year window. To add (if I remember correctly) it was also only a voucher for a day visit, so parking…
I have a feeling like 90% of these voucher do not get used.
It reminded me of the time a handful of years ago VIA Rail did a promotion for anyone under 18-19. You would received a voucher to travel VIA rail from one side of Canada to the other. I don’t remember the specifics but it was only for the train ride with unlimited stops 2-ways.
