York Region has terrible public transit and is a much closer model to the US than it is to Toronto. Heavy investment in large capital projects (fancy bus lanes), followed up by terrible service provided on the huge infrastructure investment.
It's modal share, while higher than most of the US, is much more similar. And it's because the city doesn't fund operating, cutting funding regularly.
Brampton has strong suburban transit. York Region doesn't.
Honestly, for Americans, Brampton is probably the best bet for a comparison. Strong transit ridership, huge high capacity arterials, no subway system to feed into, essentially exclusively low density housing forms. No significant student base to hold a base level of ridership. Huge amounts of highway infrastructure. Dispersed travel destinations and employment nodes, focused mostly on industrial and warehousing employment. Yet one of the highest ridership transit systems in the country. Because the city spends money to provide high frequency, reliable transit service.

If that isn't proof that good service delivers ridership, I don't know what is.
