A little late.The cost of the 407 depends on how far you take it: http://www.407etr.com/tolls/tolls-explained.html and there are fees for the plate reading if you don't have a transponder (which isn't worth getting for only one trip) As for when to hit TO and the end of rush hours? There isn't any end... but are you planning to drive into the core or simply drive across the top end (401/407)? Your going to hit slow spots no matter what time during the day. Very rarely do we get to or from Guelph into TO without stopping somewhere along the way, mostly around Milton - Mississauga. Best plans you can make though are to be going through mid morning (10ish) or early afternoon (1-2) or evening - after 8pm or so but don't expect to have a smooth ride even then. It's often a volume issue...
good luck!
I made it no problem
