I'm getting ready to submit the application to sponsor (outland) my Japanese spouse and then we are hoping to fly to Canada in July so that our family can stay together. I believe you can get a 6 month visitor visa and if necessary file for an extension. What I'm wondering is, will there be a problem if we are coming to Canada using "return" tickets rather than a one way fare? The reason why I'm asking is that one way is much more expensive than a return ticket (go figure). What do we tell the customs person? Will they even question it?
