health care?
if my cousin(canadian) marries her american bf will she lose her health care coverage here permanently? and how would marriage affect her canadian status?
a long distance relationship is difficult but before she agrees to move there she wants to know how her canadian health care would be affected. The other option is for him to move here, but he has strong family ties. So..say she starts with a temporary work visa.. what are the guidelines in regards to coverage? *we canadians hear such horror stories about U.S citizens not having enough money to get needed medical assistance*

First of all health care is a provincial responsibility so it depends on the rules of her province. In Ontario she has to reside in ON for at least half the year to be covered by the ON health plan. It would be prudent to check this out.
Marriage would not affect her citizenship.
