Juan Carlos Sandoval, 32, is accused of stabbing his ex-girlfriend and a man early Friday morning.
Police are setting up at a command post at 5 p.m. today near St-Zotique and Chailly streets.
Officers are looking for information about the suspect's whereabouts before the 4:30 a.m. incident.
Sandoval’s bail hearing, originally scheduled for Monday morning, has been delayed.
Both of the alleged victims are in hospital recovering from their injuries, which police say are serious but not life-threatening.
