On July 20 I am headed to Hamilton, On via YYZ. When I get in, I have some free time, so I'd like to go to Canada's Wonderland in Vaughn before heading to Hamilton. Canada's wonderland has no place to store my bag. So, are there any services at YYZ that transfer bags or a place in Vaughn that I can park my bag?

I am really trying to go car free because when I get to Hamilton, I board a bus that takes me to other places in Ontario for a few days. Anyone know of anything??
