The Royal Canadian Mounted Police in Nova Scotia were searching for a man on Sunday they said had shot multiple people on Saturday night.
The authorities responded to reports of a shooting about 10:30 p.m. Saturday in the small rural community of Portapique, which is about 35 miles from Truro, Nova Scotia.
A police spokeswoman, Cpl. Lisa Croteau, said on Sunday morning that there were multiple victims but she did not specify how many and whether they were injured or killed.
The authorities identified the gunman as Gabriel Wortman, 51. It was not immediately clear what was the motive for the shooting.
“He is considered armed and dangerous,’’ Cpl. Croteau said. “We are asking the public if you see him, not to approach.”
Mr. Wortman may be driving “what appears to be an RCMP vehicle & may be wearing an RCMP uniform,” the authorities said on Twitter.
The authorities said that one difference between his car and official police vehicles was the car’s number, which was 28B11 on the rear passenger window.
“If you see 28B11 call 911 immediately,” the police said.
The authorities are also asking people to avoid Highway 4 near the Hidden Hilltop Campground in the Glenholme community.
“Please stay inside your homes and lock your doors,” the authorities said.
