Nothing surprising here.  For two hundred and fifty years, especially after liquor and disease wiped out First Nations people, immigrants have comprised "a growing share of Canada's population" especially during the 1800s and early 1900s.  Three of my four grandparents were among those who came from the UK (1909, 1911, 1920.)

Moving to the present, I understand that caucasian residents of Metropolitan Vancouver will reach minority status around 2030, around 48-49%, I believe.

That's all OK, because--as always--Canada needs the people to be prosperous, and we are well within our rights--in fact, it is our responsibility--to bring who we want from where we want to keep our country the way we want. 

But...exactly who do we want?  From Where?  Why?  As long was the Canadian people are given the opportunity to decide...no big deal.  Bring 'em on.
