According to Wikipedia, Alex moved to the U.S. in 1973 at the age of 33, became a U.S. citizen in 1998 at the age of 58. Trebek is very much regarded as a Canadian, even in Canada. (RIP)
One of the favorite pastimes Canadians have is that of pointing out Canadians whom people think are Americans. Peter Jennings (also RIP) and Alex Trebek are usually the first two that come to mind. Then there's Ryan Reynolds, Ryan Gosling, Rachel McAdams, Joni Mitchell, etc. Recently I learned that HN's dang and sctb are Canadians too [1]...

But they are americans. They chose to immigrate to the US and become americans. They didn't choose to be canadians. The only reason anyone knows about them is because of what they achieved in america as americans. They couldn't choose where they were born, but they could choose where they lived and died. Both chose america.

Isn't it more like canadians pointing out the people who left canada to become americans? Isn't it rather pointing out canada as a failure and america as a success?
So, no, “immigrated to the US” does not mean “stopped being Canadian”, in either the sense of identity or legal citizenship.
