The work is scheduled to start on May 6 and will run until at least Aug. 25, according to the STM.
"There's no problem with safety. That's why we're doing this prevention. It's part of our infrastructure renewal program," said STM spokeswoman Isabelle Tremblay.
The green line station was opened in 1978 and some of its components have reached the end of their life, according to the STM.
Ridership is typically lower in the summer so the STM planned the work for that period and intends to reopen the station before the start of the school year.
"It's normal. It's like a house. You have to maintain it and to repair it once in a while," Tremblay said.
The province and the STM are paying for the renovations.
A direct shuttle service will be available for STM riders to take them to and from either the Verdun or Monk stations while the work is underway. Buses that stop at the Jolicoeur station will not be affected by the closure.
Jolicoeur is the latest station to be shut down for renovations as the STM tries to revamp its decades-old system.
In 2011, the Villa-Maria station was shuttered for the summer as repairs were made to the foundation, stairwell and street-level concrete deck.
The George-Vanier, Charlevoix and Côte-Sainte-Catherine stations have all experienced temporarily closures in previous years for repairs.Suggest a correction
