Yes mrsc08 is correct. You just need to show your passport, and your wife's health card then she can add you as dependent. The expiry is the same with your visa expiry. Any valid visa, (visitor, study, work permit) is ok. After your visa expires they give you a one time 90 day extension while awaiting should you decide to extend again. In my case, i am in the process of extending. Am doing this because my hubby included me in his benefits and I get same benefits as his BUT only if I have Alberta health card first.
