Sask residents get white tail 2 tags, plus in certain zones you can get unlimited CWD tags provided you submit the head for testing. The catch is you can only get tags one at a time...fill one, buy another.
Canadian and Non-residents just get one either-sex tag. Here in Ont it's one buck tag, plus certain zones (like mine) they offer limitted number of doe tags and/or second tags. Technically doe tags are by lottery, but as far as I know there have always been more tags available than applicatants so it's first come first served. Same for second deer - I think.
