I agree with JaxDad, use transit, but I am not sure Yorkdale is the best place. That mall is horrendous on the best days. I would consider Go Transit on the Lakeshore route. Park somewhere west Oakville, Burlington etc or east of the city Pickering, Whitby etc and take the Go Train into Union Station. My choice would be for the East end, park at Pickering Town Center, the mall not too busy to be able to find parking for a big trailer. Park in the back of the mall near the hwy 401 and walk across the bridge to the Pickering Go Train station. The Hall of Fame is right across the street from Union Station. I also agree parking anywhere downtown would be a bad idea especially due to PanAm games, even now things are getting busy. The lots near Cherry Beach, probably the best place to park a big vehicle in downtown are now full of thousands of new GM cars for the athletes/VIP's to use during the games. Try finding parking for a big trailer in Manhattan... same idea not easy.
