Since you are in Toronto the jump to New York State is pretty easy...here are a few to consider;
Syracuse Nationals https://syracusenationals.com/
Muscle-Palooza https://www.hemmings.com/musclepalooza/
Adirondack Nationals http://www.adirondacknationals.com/
The Hemmings Show is cool and combines a car show with drag racing...Syracuse Show draws a big crowd every year...Adirondack Nationals is also well attended and there is lots to do in Lake George.
All of these shows are easily accessed via NYS Thruway and 87 Northway.
Good luck..
