The Verdun Hospital is slated for a five-year, $143-million overhaul that will add two wings and transform patient care.
The hospital was founded in 1932 and several parts of the main building have not been changed much in the past 80 years.
The next extensions will add a new patient ward with 230 additional beds, and add space for the hospital's orthopaedic and plastic surgery clinics.
Those additions will mean the hospital will have 70 percent more single beds with an attached bathroom.
"For the patients it's better security, a better environment," said Health Minister Dr. Gaetan Barrette.
"When you're in a four-bed room you don't rest, period. When you're in a single room, you rest."
