Chairwoman Suanne Stein Day says the board is considering cutting the jobs due to budget cuts.
"We've received our budget rules and of course, we are suffering additional, large budget compressions. The Lester B. Pearson School Board is now over $14 million in cuts this year and some of the targeted areas are in support staff which includes librarians," Stein Day said.
It's unclear just how many jobs will be cut.
The school board plans to present its preliminary budget for the coming school year on June 29.
The school board, one of Quebec's largest, oversees English schools from Verdun to the West Island and further west off-island.
Stein Day said the board would have to consider several options, including school closures and the cancellation of programs after the provincial government tabled its most recent budget in March.
