There was heavy police presence on Sutherland Avenue at about 7 p.m. Friday.
Two vehicles were surrounded by at least 10 RCMP cruisers, some unmarked, a witness told Castanet.
Sutherland Avenue is closed to traffic from Ethel Street to Richter Street.
The witness reports guns were drawn on a truck that appeared to have been rammed by police, leaving a window shattered.
Castanet will update this story as soon as more information becomes available.
