Presto has just announced a new crop of discounts that cardholders in Ontario can cash in on. A Presto card is an essential element for getting around Toronto and the GTA, but its benefits extend far beyond helping you pay your fare. There are a slew of perks and discounts that you can access with your card to sweeten the deal, with new ones dropping regularly. Before May 29, you can use the code PRESTO20 for 20 per cent off the price of admission. As an added bonus, your Presto card can get you 20 per cent off Zipline & Aerial Game Treks, Discovery Kids Courses, and Treewalk Village at any of the parks.
