With details still murky, police said the SWAT team member was either struck by a bullet — or slammed into an object — during an ongoing standoff.
Const. Anie Lemieux, a police spokeswoman, said the standoff started late in the morning when police were alerted to workers on a property being threatened by a man with a gun.
The man, who appeared to be around age 70, retreated into his home when police arrived.
"There's at least one gunshot that was fired toward police officers from the tactical intervention group," Lemieux said.
"The police officer was slightly injured," she said. "He'll be OK."
A written statement from police described it as a "bruise" on the foot. The statement says it's not clear whether the injury was caused by a bullet or impact with an object.
Another police spokesman explained later that there was indeed a gunshot from behind the door — but it's not clear what caused the subsequent injury.
Police blocked off several streets as they attempt to resolve the incident peacefully.
