Zajdel ran for the
Conservative Party of Canada in the riding of
Mount Royal, a traditional
Liberal stronghold, in the
2011 federal election. He had been a Liberal for decades federally; he'd even considered running in a by-election for Mount Royal in 1998, but stepped aside in favour of Cotler. However, but switched to the Conservatives due to the
Harper government's strong support for Israel and
Michael Ignatieff's claims that Israel committed war crimes in Lebanon. Zajdel lost to
Irwin Cotler by less than 2,500 votes. It is the narrowest margin by which the Liberals have won the riding since 1958, and the closest that a centre-right party has come to winning anywhere in Montreal since the old
Progressive Conservative Party lost all of its seats in the city in 1993. From October 2011 to March 2012, Zajdel was employed by
Minister of Canadian Heritage James Moore as “a liaison between the Government and the city’s cultural communities.” He reportedly described the job as "connecting principally with the anglophone and ethnic communities and municipalities to see if they can benefit from various federal programs." In December 2011, Cotler claimed, after Zajdel had convened a meeting with municipal politicians in Mount Royal to explain the grants and programs offered by Canadian Heritage, and a phone campaign by the Conservatives in the riding, falsely claiming that he was about to resign, that Zajdel was in fact working as a "shadow MP," offering to help municipal politicians secure grants and services, and preparing for a second attempt to win the riding of Mount Royal. Zajdel denied involvement in the phone campaign, stating that it was "a party thing." ==Criminal charges==
