I find U of O lacks in comparison to U of T, and that the St. Lawrence Market area and Byward Market areas are roughly equivalent.
The re-done portion of Bloor St. and Yorkville as a whole surpass any Ottawa equivalents, just as some features of Ottawa are better than Toronto's.
All in all, though, I would say that the two cities are largely equivalent in terms of public realm. Ottawa doesn't have many overhead wires but they don't have streetcars either.
Look at this place steps away from Byward market and tell me it isn't in worse shape than the vast majority of TO:
Do consider Ottawa is much smaller, so you need to be fair when comparing ...
Parts of UofT Toronto's campus are hard to surpass anywhere in North America !
This is just silly anyway ... how about lets all admit Ottawa has better food trucks (as apparently some people like that) and leave it at that.
