We want to have PR in Canada, but are worried about the medical exam part. We are in good health, but have a history that includes a heart valve replacement (2 years ago) and an assortment of other things like C-section, broken arm, pinched nerve, and I saw a counselor years ago for depression during a divorce. Are these deal breakers? We are almost 60 years old, by the way. We are college educated professionals who meet the criteria for skilled workers. Any advice would be appreciated. Thanks!
