It does not matter where I go here, there is one thing I hear when people find out I am Canadian
"Where in Canada are you from? My aunt married a Canadian"
Everyone knows a Canadian or is related to someone in Canada, or someone they know married a Canadian and so on.
I walked into the flower shop...Where in Canada? My sister married a Canadian, she moved over there, are you close to there?
Granted we are close to the border, when it was easy, there were Canadians and Americans border hopping for romance all the time. Everyone over here is related to some Canadian and same on the Canadian side. The only difference between us is the side of the border we live on.
The joke with my husband is that when we see a Canadian Licence plate..."Do you know them?" he asks every time.
There are over 31,612,897 people in Canada spread out across 9 970 610 km²
granted compared to the US where there are 307,212,123 people that are crammed into 9,826,675 sq km
So the answer, I have no clue who your Canadian family are just because they moved there. I do not know every Canadian.
