For the folks who will be traveling by air for the concerts the Toronto transportation system is very good for getting to all points in the city and back.
www.ttc.ca will have all the necessary information and there's a ground transsportation booth in the airport which can also provide assistance.
The Toronto folks are quite friendly so don't be afraid to ask for help with directions if need be.
An adult fare is $3.00, or if you're a senior like me it's $2.00 (a Canadian "toonie" coin)
Also as Char mentions here, the pub is a great place for anyone who enjoys a good pint of beer, so Steve, you'll be in good hands and it will be nice connecting with you.
