Hassainia ran as a member of Parliament with the NDP in the Verchères riding.
However, last August, she left the party over what she said was a disagreement on policy relating to Israel.
The NDP press secretary says the falling out was due to her attendance record.
In 2014, she was present for just 16 of 269 votes in the House of Commons.
During her mandate, Hassainia had two children and says she has made a choice to be there for her family.
"It's very, very rare that a vote passes with a majority government, so I allowed myself to do this because it's not my little voice that makes a difference," said Hassainia.
She also said she didn't think her vote mattered as an Independent MP against the government.
One former employee of her constituency office says Hassainia hasn't been in the riding, either.
Jonathan Pare said he would have a meeting with constituents in Hassainia's place.
"The people tell us, 'It's you who is here, not her. How can that be?' She must be there," he said.
Pare said he quit after he realized how uninvolved she was in her duties as an MP.
