Doesn't matter. She has a spouse. She cannot sponsor you.
In order to qualify to sponsor you ALL of the following would have to be true:
- She has no spouse or common law partner
- She has no children
- Both of her parents are deceased
- She has no other family members in Canada (e.g. siblings, aunts, uncles, etc.)
Because she is married, this disqualifies her from sponsoring you.
Again, you will need to qualify on your own through a program like Express Entry.
