As of Canada's election results, Raymond Chan the former Minister of State for Multiculturalism, and who introduced the ACE Agreement-in-Principle, is still trying to do damage control by stating that the Chinese Canadians still voted him in office and that the head tax issue wasn't that big an issue. 

But the numbers don't lie.  The Tory polls swung upwards immediately after Paul Martin made what appeared to be an insincere personal apology for head tax redress.  The Liberals are now out of office.  The NDP led the charge for a proper apology and redress, and their numbers doubled in BC, and increased across the country.  The Conservatives supported an apology and direct compensation for surviving head tax payers, and their numbers increased.  The Bloc supported head tax redress and their numbers increased.

Raymond Chan may have won “first past the post” but Conservative Darrel Reid was only 1, 821 votes behind Chan's 18,107 votes.  NDP Neil Smith garnered 5,944 votes and Green Party Richard Matias snagged 1,916, more than enough that could have combined with Reid's to overtake Chan.  But to be fair, Chan fought a close battle to retain his seat in Parliament.  He had a good campaign that responded quickly to both the Chinese and English language press.  He is the only Chinese Canadina MP in Vancouver's Lower Mainland, and you can bet all of the different groups in the community will be asking him to be accountable for issues important to the Chinese Canadian community – no matter how broad the community really is.

The only Liberals in BC who won by large numbers were Ujjal Dosanjh, David Emerson and Stephen Owen, who together spoke out against Chan's line in the sand, and found the 2nd opinion regarding legal liabilitiy of an apology and forced Chan to change his tune.

If the head tax redress wasn't an issue, then why did Paul Martin issue a personal apology and reverse his party's decision to originally not issue an apology in the House of Commons?

The following is an analysis breakdown by by Victor Wong of the Chinese Canadian National Council, to which I have added some extra comments.
