Wow! Missed all the action! I live about 300 k northeast of Thunder Bay, so I am in the boonies. We only have 3 CO's to cover an immense area, plus the government limits their mileage with some ridiculous gas budget...however, despite the limitations placed on the CO's, I still get stopped at least once a season. Just to clear up some misunderstandings... I can drive for five minutes and be on Crown Land. There are three or four sand pits close to my house where most people go to target shoot, site in rifles etc. Although I am sure I could convince the CO's that I was only target shooting if I took out my SKS, or Enfield, or Mosin during big game season to one of the pits, I prefer not to be bothered with the hassle, and have my tags.
Once big game season is over, there is no limitation on the calibre of rifle you can carry in the bush up here. You can shoot rabbits with your SKS if you want too. I carry either my 870 or my Baikal 7.62 x 54 from May till the middle of August on all my canoe trips, and the CO's know it. They don't have a problem with it, they know it's for the occassional bear I might need to scare off.
The CO's up here are pretty good guys, they have a fairly onerous task...our bush is invaded every October by 100's of hunters from down south and across the border, and some of them are unsavory characters....not to mention some of the locals who live to flaunt the rules....if i've got to spend an extra forty bucks to carry my rifle for a couple of months, I don't really care. I'm not paying any range fees, my shooting is free all year round.
