For a limited time only (July 27 to August 16), discounted tickets will be available through the CNE’s exclusive retail partner, Shoppers Drug Mart. Advance tickets are also available online at theex.com or at GO Transit (Lakeshore line stations only).

For complete details, visit www.theex.com for updates on tickets, attractions and special events. All events are free with admission to the CNE.
Tickets are 33% off, I'm not sure if this includes the "Ride All Day Midway Pass". This is the cheapest prices that I was able to find.
