What percentage of canadians are first nations?

Approximately 700,000 people in Canada have their race status of Aboriginal registered with the Canadian government. Only those with such a registration, or treaty number, have proven their racial purity to government standards.

That means that there are 700,000/35,000,000 = 0.02 x 100 = 2%, approximately 2% of Canadians are registered First Nations.

But for various reasons many more than that claim aboriginal ancestry, at least another 700,000, so the number could be as high as 4% maybe even 5%.
