My parents are Super Visa holders and have been in Canada for the past 1 and a half years. They are planning to visit their home country for a month and a half and then return to Canada. Their Super Visas are still valid for a few years. Will their short stay outside Canada create any issue at the port of entry when they return to Canada? Or can Super Visa holders leave and re-enter Canada as many times as they want during the validity of their visa?"
