Travelling through Toronto at any time is an adventure, best times to avid are am and pm rushes. I would stay away from 407 more trouble than its worth. We got double billed towing the car and it took a lot of convincing until they got it right, now if you take 407 stay on to the end and then you will travel hwy 7 east and stay on it until you get into Whitby then go south on Thickson Rd. back to hwy 401. Personally I would stay on 401 get into the core lane and tough it out. Now oil change we purchased our unit at Owasco R.V. in Whitby phone 1-866-579-2267 they are located in the area of Hwy 401 and Thickson Rd. and i believe they do oil changes as well, be aware there and not many r.v. parks at Toronto.
As always travel safe and enjoy
