Ottawa's stations hit some of these (redundant elevators and accessible fare gates), good number of fare vending machines, but misses on a lot of others with small, cramped subway entrances, narrow platforms, single or no escalators (expectation Rideau and one Parliament with doubles).
Montreal stations are amazing but lack accessibility. Toronto seem too cramped or way overbuilt. Vancouver strikes a good balance, if it wasn't for single elevators and some cramped Canada Lines stations and trains (we stayed in Yaletown once, and even outside rush hour, the lack of fare gates were problematic).
Can't speak for other systems in Canada.
