She stated that she will not seek to enter the federal House of Commons via a by-election, saying that she wants to "have a foot" in both Quebec City and Ottawa.

It also approved a supplementary payment, which would have resulted in a total salary of $200,000 once her term as a member of the Quebec National Assembly ends with the 2018 provincial election.
