That's my neck of the woods.
I really like the ranges at Gat Guns, Dundee. They have 3 ranges that allow you to shoot at 21', 50' and 75'. The people that work there are friendly and the ammo prices are fair. Range fee is $25.00 and the offer a good selection of targets.
Buffalo range in Ottawa is all outdoors, but very diversified. The have a pit area where you can shoot anything, from full auto machine guns, pistols, shotguns. Heck, I saw a guy shoot a minature cannon there once. They have two shotgun ranges, a pistol range, a slug gun range and 150 yard. But Buffalo does not sell any ammo. You pay an entrance fee that is good for a full day. You must bring your own targets, no plastic allowed.
Hope that helps.
