Appreciate that you don't have a car..and neither do we now and then, when I lived in Toronto for several decades and went bike shopping when I first returned to cycling awhile ago.

Hope you will consider using the subway system there during off-peak hrs., since there are several bike shops near the subway line about no more than 20 min. walk for some. Of course, not all the subway stations have elevators to get the bike out of the station without lifting the bike up a staircase..but you will know from signage the wheelchair accessible stations in T.O.

And you can bring your bike onto the G.O. train on weekends, if you are out in the suburbs.

After that, once you will discover good interconnected bike routes in Toronto that really can allow you build routes that are small in distance to huge..ie. riding 100+ kms. in 1 day all within Metro Toronto.
