Yes, that is the crux of the matter (stop n go training is no good.)
As far as I know, there is very little racing happening in Toronto - the closest regular series would be the Midweek crit in Mississauga. That's irrelevant though - people live in Toronto and they are going to train on the roads, especially during the week. There's thousands of us, and every day on Strava you see hundreds of people doing fast laps of HP in the early morning. That's just not going to stop.
Personally, I'm all for paying out of pocket to license a space and put an end to these tensions and general combative nonsense.
