Please advise-- I plan enter Canada by personal car using my U.S. Greencard, because my Canadian PR card is expiring in Aug. So to avoid to be flagged at the port due to lack of residency obligation, i have to using my U.S. Green Card. After enter, if i stay for two years then apply for the PR renewal, is this possible? My concern is that if i don't use Canadian PR card to enter, would that be a problem when i renew the card? Thanks.
