Canadian Cities generally faired much better for true urban expressways, with Toronto being the only one with a big, downtown expressway that isn't buried. And even then, it's only one which was built through lakefront industrial areas at the time and only removed a relatively small amount of residential areas in it's construction.
Montreal does also have a downtown freeway, but it's buried through the core so it doesn't really feel like it does.
Some Cities had big plans for freeway loops though..

Toronto, like many cities also had a larger planned network (only the solid lines got built):
