Editing Michael Chong (section)

===Conservative MP===
In early 2004, the Progressive Conservatives merged with the Canadian Alliance to create the Conservative Party of Canada. Chong joined the new party, and in March 2004 defeated Marty Burke to win its nomination for Wellington—Halton Hills.[ He was elected in the 2004 federal election, defeating Liberal Bruce Hood by over 2,000 votes.

Chong is primarily known as a fiscal conservative, and is considered a moderate in his party. He declared his personal support for the Kyoto Protocol during the 2004 federal election, despite his party's opposition to the measure. He supported Elizabeth Witmer's bid to lead the Progressive Conservative Party of Ontario in 2001-02, and supported John Tory for the same position in 2004.

Chong wrote an opinion editorial for the Globe and Mail newspaper in late 2004 entitled "Canadians without hyphens", criticizing John Barber's suggestion that there were not enough Chinese-Canadian MPs representing areas with large Chinese populations. Chong noted he was elected in a riding with a 97% caucasian population, while John McCallum was elected in Markham—Unionville, which is more than 60% Asian. Chong argued that these results reflected his idea of Canada, adding that he favoured the creation of a "common Canadian identity that will allow for greater understanding among ethnic groups".

Like most Conservative MPs, Chong voted against the legal recognition of same-sex marriage in Canada in 2005. A majority of MPs from other parties supported the measure, however, and same-sex marriages were granted legal recognition. In December 2006, Chong reversed his previous position and became one of thirteen Conservative MPs to vote against re-opening the marriage debate.
