I was not aware that Seattle was in Canada? I never said the States was not a racist country. They have so many different groups of racists that you can find at least one place where each culture is not accepted. You go to the more dangerous places like Oakland or Chicago and you are lucky to make it out alive if you're white. You go to redneck central as anyone of color and the same thing. Canada does not have places like this. You get some mild hate in the Bible belt of Manitoba but it's far from not being able to walk down the street without being jumped and stabbed.
My original point was Canada is a safe and accepting country. Old school parents from all colors and backgrounds are more common to not wanting inter breeding. I know lots of asians , africans, europeans all which the parents frown upon their children dating someone from a different culture... this isn't anything new. I'm going to assume your father wasn't part of some kind of group that hunts down natives.
I'm going to guess that many people under 40 have no issues at all with their children dating someone from a different background. The younger generation in Canada are so much more accepting and in my opinion the country is moving in the right direction rather then what they did in the olden days.
