At least 16 other people were reported injured.
Montreal police confirmed that at least one suspect had been "neutralized." Television images showed police officers dragging a bloody body out of the main doors of the building.
Police wouldn't immediately confirm whether there was a second suspect. However, there were reports that a second gunman fatally shot himself at the scene.
Students inside Dawson College told reporters they heard several shots in the building around 1 p.m.
Eyewitnesses say they saw a tall skinny man, wearing a black trench coat and a Mohawk haircut, walk into the cafeteria carrying a large gun. He apparently fired several shots.
Student Michel Boyer sought shelter behind a reception desk after seeing a gunman and fleeing from the vicinity of the shootings.
"I thought this was fake, and it was just an excuse to get out of class," he told CBC Newsworld. "I did run away as soon as I did see that it was real."
His voice shaking, he added, "It was the most scary thing that has ever happened to me."
Boyer said he saw at least one man holding a gun.
"I'm only 19 and to have flashes of your life and the people that you love going by you, it should not be allowed. It was highly traumatizing."
Dawson College instructor Arielle Reid said she was in her office when the shooting began.
"I heard the shots and a student ran into my office," she told CBC Newsworld. "People don't know what is going on and they don't know what to do."
An eyewitness told CBC News she was sitting outside Dawson College when she saw a tall, white man wearing a long black trench coat walk down the street with a large gun. He was with a number of other people, she said.
The man, who the witness described as about 19 and wearing studs and piercings, fired on several people in the area, she said. The woman said she ran and hid in the bushes as debris from the gunfire scattered around her. She ran again until a woman let her inside her apartment.
Hundreds of students fled the building, and the area was been cordoned off. Police officers wearing bullet-proof vests are keeping people away from the college.
"They're telling me, 'Go the other way, lady, you're in the line of fire,' " said CBC News reporter Nancy Wood at the scene.
Hundreds of officers surrounded the building in downtown Montreal, cordoning off a park facing the school, as well as the Alexis Nihon Plaza, a nearby shopping centre.
Students and staff sought refuge at nearby Concordia University.
