A former RCMP officer has been charged after Ontario Provincial Police seized a massive cache of weapons — including machine guns, a cannon, grenades and thousands of rounds of ammunition — at a Bancroft, Ont., home.

The arsenal was found last week in two hidden compartments built into the walls of the house, located in the heart of cottage country, police said Tuesday.

"What this investigation tells us is that copious amounts of firearms and ammunition were collected, stored, and sometimes even created well away from big-city Ontario," Det. Insp. Patti Dobbin told a news conference Tuesday
