I don't think that numbered streets are very common in eastern cities, although there are some in Quebec. Owen Sound is the only city in Ontario that I can think of with a full-fledged numbered street grid, probably because it would have been one of the last cities in Ontario to be established. I'm sure there are some elsewhere in Ontario, though.
Out west, the only city that might not have them is Victoria -- again, probably because it is older than other western cities. Some places just have numbered streets (Vancouver, I think) but usually it's both. There were various variations on the system aimed at ensuring infinite (or nearly infinite) expandability -- the "crossed 100s" as in Edmonton where the central street is 100th, or the more common Calgary-style Centre Street formation with 1st St./Ave. N. etc. to the north and 1st St./Ave. S. etc. to the south, which is infinitely expandable but creates confusion with its duplicated names. Saskatoon, like Washington DC, has some lettered streets.
