I had a question I know that I am not allowed to leave Canada while my application is being processed but my wife and I want to visit Toronto and see Niagara Falls but they I heard require a passport. Would that be considered leaving and coming back? Because sometimes when we drive down from Winnipeg to Minneapolis the immigration officers do not stamp my passport or do anything. Would that still be considered leaving and coming back? Because I don't want to void my application and have to do it all over again. Please advise thank you
