The shooting happened early Sunday morning in Kimmirut, a tiny Baffin Island hamlet where an RCMP officer was shot and killed in 2007.
Const. Ian Allen says both officers were home with their families when the gunshots hit their residences.
An RCMP emergency response team was dispatched from Iqaluit and a 22-year-old suspect was arrested following a tip from a community member. Police say the seized a loaded .22 calibre rifle.
Investigators believe alcohol was a factor.
The suspect is in custody and will likely be transported to Iqaluit where he'll appear in court, police say.
Allen says Sunday's incident brought back memories of a fatal shooting targeting an RCMP officer.
In 2007, Const. Douglas Scott was fatally shot while in his vehicle in Kimmirut by Pingoatuk "Ping" Kolola, who was later convicted of first-degree murder.
"It is unusual that members of the public do target the RCMP and their families and their residences. I'm hoping that this is an isolated event, along with the other event that took place a number of years ago," Allen said.
Police say they don't know the motive for Sunday's shooting.
