He was a candidate for the New Democratic Party (NDP) in the 2000 federal election in the riding of Scarborough—Agincourt, and for the Ontario NDP during the 2003 provincial election in Scarborough Centre. Laxer was also an unsuccessful candidate for Toronto City Council in Ward 6 (Etobicoke-Lakeshore) in the 2010 municipal election. Laxer subsequently began the Ginger Project calling for the Ontario NDP to issue a comprehensive manifesto of polices and build support for their ideas rather than put all their resources into winning marginal ridings.
We feel that this strategy should be abandoned, as it has failed to produce any tangible results during an election.
The NDP should instead adopt a policy that ensures each riding association has the ability to reach every household in their riding at least once during an election campaign. We should force the other parties to have to engage us seriously in every riding in the province."
He and the Ginger Project left the NDP in 2011 due to its cancellation of a policy convention and what they viewed as the silencing of left-wingers telling the Toronto Star, “I was surprised that they would not have a policy convention prior to an election." Laxer was one of two official spokespersons of the party from 2011 to 2012 and is currently the party"s chairperson.
In 2010 and 2014 Laxer ran for City Councillor in Toronto"s Ward 6 Etobicoke—Lakeshore receiving 717 votes in his first effort and 305 in his second. Laxer is a social activist who opposes men’s rights groups.
In 2015, he told the Toronto Star he had been encouraging people to fight the Canadian Association for Equality’s inclusion at the LGBT Pride parade because he alleges the group is anti-feminist and "they don’t reflect the values of Pride".
Michael Laxer is the son of writer, academic and one-time NDP leadership candidate James Laxer and grandson of Robert Laxer.
