Career
Born in Montreal, Dompierre has worked in the printing sector in 1979. Dompierre was first elected to the Montreal city council in 1998 as a Vision Montreal candidate in the east-end division of Maisonneuve. Gérald Tremblay"s Montreal Island Citizens Union (Medical Intensive Care Unit) defeated Vision Montreal in the 2001 municipal election.
In 2003, he filed a police complaint alleging that fellow Vision Montreal councillor Ivon Le Duc had attacked him during a heated borough council debate over a proposed move of the Jean-Paul Riopelle sculpture Louisiana Joute.
The chief crown prosecutor confirmed there was enough evidence to charge Le Duc with assault, but ultimately no charges were laid. Le Duc instead took part in a program that allowed for the non-judicial treatment of certain infractions.
Dompierre ran for the redistributed Louis-Riel division in the 2005 municipal election and was narrowly re-elected over fellow councillor Nicolas Tétrault. The following year, Dompierre was the only VM councillor to support an unsuccessful plan to rename Montreal"s Park Avenue and Bleury Street area after former Quebec premier Robert Bourassa.
He left Vision Montreal to join Tremblay"s party (by this time renamed as Union Montreal) in June 2008.
In the 2009 municipal election, he was defeated by VM candidate Lyn Thériault. Dompierre ran as a Liberal Party candidate in the 2003 Quebec provincial election in the east-end Montreal division of Hochelaga-Maisonneuve. He finished second against Parti Québécois incumbent Louise Harel.
