Yeah, sharing with cars is fine on gravel roads and small country roads, but even moderate amounts of traffic on rural roads makes for a pretty unpleasant and daunting experience in my opinion. I do hope quebec improves the Route Verte, hopefully it can serve as an example for the rest of Canada.
The Go train can be used ti get further out and there is some good cycling not far from Hamilton and a lot of good multi day routes out of kitchener like the BT700 but im personally a little underwhelmed by southern Ontario geography, its very fast and goes through lots of farmland, and the on-road portions cam often be sketchy. I have had an overnighter in mind that I've wanted to try out from Barrie that would take me north into the shield, but its a route I sort of made up myself and haven't had a chance to scope it out. Im a bit nervous to attempt an unknown route but I may just go for it and hope for the best since I wont be too far from help if something goes wrong.
A good option, but nowhere near as durable as Darn Tough, I dont know if im just really hard on my socks but I burn through these guys in a year. Darn tough socks last me 2-5 years depending on the style
