First choice is to find out whether she has a sibling or not. There is a 25% chance to get same genetic background from siblings.
Second choice is from her parents but only ~50% genes from either parents are same. Plus her parents must be healthy enough to donate their bone marrow.
Third choice is to look for same type bone marrow from strangers. It's better to search the bone marrow from Tai Wan. Lots of patients of Leukemia in China found the bone marrow donors from Tai Wan.
My suggestion is to get the bone marrow transplantation in China. It should be fine to get the chemo in Canada. However, if she want to be cured, bone marrow transplation is the only way to save her life.
Bon chance!
