We’ve tried a few options at YYZ and haven’t been to satisfied with any of them! We’ve done the cheapest lot at the park & fly and the bus didn’t come frequently at all and made stops at all the other lots before bringing us to the terminal so it was much longer than expected. We tried another one last fall that was ok but the parking lot was not in great shape and didn’t seem super secure, although everything was fine so we’re going to try something else next time!
