I flew GRU-YYZ on Friday, an entirely uneventful flight. When I arrived at YYZ it would have been nice to take a shower since I had a breakfast meeting and then a long drive home. There are alleged to be showers in the T1 Maple Leaf club, but international arrivals dump you landside, and they told me I couldn't get back airside without another boarding pass. The nice lady at an info kiosk suggested I go to the airport Sheraton.

This seems so wrong, you can only take a shower if you're connecting, in which case you probably don't have time, anyway. I realize that with the magic of self-printed boarding passes it would be the work of a moment to print a fake one to get back airside to get into the club, but is there any way to do this legally?
