It's Montreal, so you are indeed correct. Honolulu did actually open the first segment of a very similar automated light metro system just 2 weeks ago, although it doesn't have the same service frequency as ours. It's still enough to make it America's newest metro system, though!
Meanwhile in Toronto, there's a bunch of public transit "promised" but all of them are going to run over the deadline by like 5 years. It's still way better than nothing.
