Police received a 911 call around 5:22 p.m. Friday and responded to the school on Avenir Avenue.
The shooting took place in a green space near the college, according to Laval police spokeswoman Geneviève Major.  Police set up a perimeter around the school that prompted a lockdown as officers searched for at least one suspect.
The injuries were not considered life-threatening.
Sources said CTV staff and students were first told about the shooter by a witness screaming down the halls for people to take cover. 
The students were taken to safe areas.  Their parents wait anxiously for updates as many rushed to the scene.  Traffic was backed up in both directions.  The school remained on lockdown several hours later.
Laval police are searching the halls of Montmorency College in Laval, Que.  after a shooting was reported nearby.  The school was placed on lockdown as parents waited anxiously outside. 
“They are safe from what I gather from her messages,” one mother wrote in a message to CTV Montreal.  Her daughter is in school.  “There was panic inside.”
Quebec Francois Legault took to social media on Friday to call the shooting “alarming.”
“My thoughts are with the victims and their loved ones,” he wrote.  “We will relentlessly fight gun violence on our streets to keep QC a safe place.”
The incident comes on the same day as another major police operation at a college south of Montreal, which resulted in the arrest of a 19-year-old.
