"....many people who are now Lost Canadians..."

Honest Question : I did not know there was a major outcry for this...do you have numbers?

Secondly, while this gets into semantics, are we talking about people who came to Canada as adults, obtained citizenship, went to a third country (likely the USA), or returned to their home country, and now having been 25 years out of the country, are considered "lost Canadians"??...sorry, while Canada may have extended citizenship to these people at a time, my heart is not quite tugging for them, without more details..
