I can find no reference to his age, or to the year in which he immigrated to Canada. Hong Kong was transferred to China on July 1, 1997, 29 years ago, so I could not determine if he immigrated to Canada when Hong Kong was British, or part of China. But unless he is younger than 41, it was before Hong Kong was transferred back to China, and he would probably have been, rough;y interpreted, a British Subject in Limbo, (A British passport to the rest of the world but not really a British passport in Britain). This certainly goes towards addressing any issue of bias, and if he could hold a Chinese passport by birth.

This certainly does put an interesting twist on the Canada-China dialogue. It is really difficult to sort through fact-from-fiction, depending on where you were indoctrinated with your Chinese history knowledge.
Unfortunately, I see this tactic used by the PC members quite frequently, so I can accept that it is a tactic that party promotes in their members. It is, unfortunately, extremely common in the House of our neighbors to the south of us.
