. . . .and when are you leaving? I'm at a loss why you would not just renew anyway to keep it current. Unless there is no chance of getting it back in time. But then I came close to getting thrown out of Canada once on a short-date till expiration passport by a woman who was clearly trying to be a problem. (Years ago. At the time you technically didn't officially need a passport for Canada. But at the airport they were clearly expecting you to have one).
