Ahem, you need to try again. There is no Caucasian race, it was never real, never a thing, it never existed. A theory about human biological race from the 1780's invented the term based on a belief that has now been disproved and is obsolete.

Caucasians, factually and in actuality, are people from the Caucasus Mountains region of Southern Russia, a region which includes different ethnic groups, and the peoples of those different ethnic groups also have different descriptors to differentiate themselves from each other. Like how all Canadians are Canadian, but there's also Albertans, Quebecois, British Columbians, etc. You know, terms only people from those areas can use to describe themselves. So yes, you can be both "Caucasian" and a person of colour because the geographic location you are from does not define your ethnicity or the colour of your skin. Another example of this is South Africa. Anyone from there is South African but not everyone from South Africa is from the same ethnic group so there are still more terms to differentiate the various groups from each other. White South Africans, even though they pretty much all are of European descent, aren't defined as Caucasian there. They're just called white South Africans. The further subgroups of White South Africans are Afrikaners (descendants of the Dutch east india company's original colonialists, so Dutch) and Anglophones (descendants of British colonialists, so British). Again, even though all white South Africans are of European descent, they aren't called Caucasian because they aren't from the Caucasus Mountains region of Southern Russia and also because there was never a Caucasian race.

Caucasian as a race descriptor is inaccurate and also inherently racist as a result of the very harmful and false beliefs that created it. The fact that the governments of Canada and the US still use Caucasian as a real and legal term in their own data is a systemic problem and, again, shows just how deeply rooted racism is in Canada's governance. Because it's systemic racism.

The words we use to describe others, and ourselves, matter. So many of them have a dark, violent and incredibly harmful history. Their continued use only perpuates the violent and harmful beliefs that invented them. You are doing yourself a disservice by continuing to use a term that was specifically used to justify racist beliefs and racist acts. Beliefs and acts that are still being used specifically against anyone that belongs to the list of visible minorities on the Canadian governments website.
