They do not have OHIP in Alberta. OHIP is only in Ontario. Since you only stayed for 2 months and did not get OHIP, it is a question if you really settled in Ontario and certainly you will not be moving from Ontario to Alberta, you are moving from your home country to Alberta. You can contact Alberta health here:
http://www.health.alberta.ca/contact.html Ask them how they will treat your move. Either you will have first day coverage or they will make you wait 2 + balance of the 3rd month. That is, if you move on some day in February, you would get your AB health coverage on May 1st at the latest.
