Police in Nunavut and Quebec say they've busted up a major pot-smuggling operation.

More than 1,000 cannabis plants have been seized along with 22 kilograms (50 pounds) of marijuana from a Montreal grow-op. Police say about 13 kilograms of the marijuana seized was destined for Nunavut.

"Three arrests were made out of Montreal, six arrests out of Nunavut," said Cpl. Yvonne Niego with Nunavut RCMP.

"In Nunavut, arrests have been made in Arctic Bay, Resolute Bay and Kimmirut. There have been arrests and searches conducted in Nunavik communities."

The bust was a co-operative investigation by RCMP and Kativik Regional Police, with help from Canada Post inspectors.

Police say the pot was grown in Montreal, and mailed to Nunavut and Nunavik. Local dealers would then sell the drugs in Northern communities, at high prices.

Raids were conducted yesterday in some northern communities, as well as Montreal.

RCMP say the trafficking ring has been operating for several years. A 52-year old Montreal man is alleged to be the main distributor. He was arrested Tuesday.​

Police say the investigation is ongoing, and there could be more arrests.
