Vision Montreal won a majority of seats in this election under Bourque's leadership, and Le Duc initially served as a pro-administration backbencher.
[4] The following year, he led the executive committee in amending the city's urban planning by-laws to require a 7.5 metre gap between garages in new developments.
[8] In January 2003, fellow Vision Montreal councillor Richer Dompierre alleged that Le Duc attacked him during a heated borough council debate over the removal of a Jean-Paul Riopelle sculpture.
[10] Le Duc resigned from Vision Montreal in February 2003, saying that he felt "betrayed" by Pierre Bourque's decision to run for the Action démocratique du Québec (ADQ) party in the 2003 Quebec provincial election.
Le Duc was unexpectedly rejected as MICU's candidate for borough mayor in the 2005 municipal election in favour of former provincial cabinet minister Pierre Bélanger.
[13] Le Duc subsequently resigned from MICU and again served as an independent, openly snubbing Tremblay at a major public event in his community.
The following year, he was profiled in the Montreal Gazette for selling prefabricated houses to Afghanistan in co-operation with a construction firm based in Kabul.
