I live in Toronto and was in the Chengdu metro a month ago. I didn’t do a close inspection but it was fine. Honestly probably better than Toronto. The trains had AC and the terminals that I went to were not crumbling.

I think this meme is pretty reasonable. Toronto had a great start with subways, and still has huge ridership. They also have an excellent bus network. But the funding is very tight and the city has long prioritized inefficient personal vehicles. But it is a good point that you are comparing cities that an order of magnitude apart in population. Toronto also has 2 train lines (one light rail that should be opening within a year, and one subway that is probably 10 years away from opening) which are great to see, finally showing some investment in public transit. But the rate is nowhere near what the political will in China allows and also has a huge focus on new projects rather than keeping maintenance of existing infrastructure.

In many ways this is a wakeup call. If we wanted this level of infrastructure we could have it. But we need to actually commit rather than continuously slashing budgets so that we can let the rich pay less taxes and continue to subsidize car ownership.
