Canada has 34 ethnic groups with at least one hundred thousand members each, of which 10 have over 1,000,000 people and numerous others represented in smaller amounts

Mind you, the Canadian pictogram is 9 year old data. Census 2011 should bring out some fun results.
That's 260k input annually, that's 2.34m people more since. Significantly more varied than Australia.
Mind you, I'm not knocking Australia, I just think all this praise of how everything is great there and how we have it cold and shit here is just red herring.
Australia isn't handling its new found multi-racial-ness well at all.
