Groulx

It was created for the 1981 election from a part of the Terrebonne electoral district.

In the change from the 2001 to the 2011 electoral map, it gained a small part of the city of Blainville from the Blainville electoral district; it did not previously include any part of that city.

From its creation in 1981 until 2007, Groulx was a bellwether riding always sending a member from the governing party to the National Assembly.

In 2014, the PQ nominated Martine Desjardins, former leader of the FEUQ during the 2012 student strike.

While the PQ began the campaign with a strong lead among francophones and heavily targeted CAQ-held ridings such as Groulx, the fall of the PQ and rise of the CAQ during the last two weeks of the campaign kept this riding in the hands of the CAQ, albeit in a tight 3-way split with no candidate receiving more than 31% of the vote.
