The ERs in GTA are just always clogged. I've had to deal with multiple instances of 10+ hour waits in the ER. When they were not addressed in time, one such incident got worse, and ended up in a 10 day serious hospital stay (love the logic on that one).
Getting an appointment with any sort of specialist is also a gauntlet.
I'm an immigrant and it was surreal hearing the new Toronto mayor talk about how much she accomplished as an immigrant to Canada. It was indeed possible when she and I came to this country. It is a fantasy today. GTA has become a terrible place to live in a very short time period.
