A friend from the Toronto group bike ride community directed me to Jeff Allen’s intringuing and beautiful cartographic work.
One especially striking map – which supports my view that bicycling has become the best and fastest form of transport in Toronto – shows which areas it is faster to reach from Yonge-Bloor by bike than by transit during rush hour:
You can get a long way! Straight north to York Mills. Southwest past the mouth of the Humber. Southeast past Tommy Thomson Park and into Scarborough.
The map is from 2016, but I would imagine things are worse now with transit underfunding and all the slowdown zones, plus all the streets blocked up by summer construction.
