Thanks for that point. I've been away from Toronto for five years, and taken the UPX up to Weston from Bloor quite a few times to run a wonderful dog (I borrow him, he loves it, it's an *adventure*) down the Humber to the waterfront and then east along the lake. I'd thought to take him north for a change, but the idea of dragging a dog on a leash (I put him on the leash on the roads) while walking a bike on that really awful stretch of Weston Rd makes my intuitive hesitation correct. I've looked from the GO train many times to see if there's a path under the new bridge, but can't see one. The only consolation was with my last dog (I'm between dogs now, so borrow this one) was the ice-cream place just before heading west down to the Humber after getting north of the bridge. My last dog used to get one every time we went past there. Memories....
For anyone wondering, taking the GO train (dogs only allowed on the UPX) up to Malton allows you to wind your way up to the Claireville Reservoir on some local trails to attain the *Source of the Humber Trail*! Cycling down the northern stretch five years ago, there is very little traffic on the path, dear sightings are common, the occasional one will even run with you, but they're skittish, keep on the brakes. If you don't have the time to break-free to do real distance cycling out of town, but need a buzz, it's a good warm-up run. If you take the UPX, get off at Weston, and the path is just across Weston Road and down the valley.
