"Canada is multijuridical," she said. "There are Indigenous legal traditions along with civil and common law, and an Indigenous Supreme Court judge would bring another legal perspective and another set of tools and way of understanding human problems to the table."

There are many legal traditions but their merits need to be considered against the standard of the current laws we are governed under. I don't see why the current system , fairly applied, can not accommodate all Canadians (In fairness I have not studied the issue closely enough yet so my views may change). Logically, should we also be thinking that Sharia law is something we should consider as providing "another set of tools and way of understanding human problems"? 

I would welcome a First Nations judge but the main consideration in order that Canadians' confidence in our legal system is maintained should be their legal competence, not their ethnicity/gender/religion.
