Victor: No, I'm saying the MNR says it's illegal.
Here's the relevant part from the 2014 Hunting Regulations, p.79:
Firearms
"If you are hunting small game in an area where there is an open season for deer, moose, elk, or black bear, you may not possess or use a rifle of greater muzzle energy than 400 foot-pounds or shells loaded with ball or with shot larger than No. 2 shot (non-toxic equivalents include steel shot larger than triple BBB, or bismuth larger than double BB), unless you possess a valid licence to hunt deer, moose, elk or black bear as the case may be. This restriction does not apply south of the French and Mattawa Rivers during an open season for deer that is restricted to the use of bows.
A person hunting small game may not carry or use a rifle of greater calibre than a .275-calibre rifle, except a muzzle-loading gun, in the geographic areas of Brant, Chatham-Kent, Durham, Elgin, Essex, Haldimand, Halton, Hamilton, Huron, Lambton, Middlesex, Niagara, Norfolk, Northumberland, Oxford, Peel, Perth, Toronto, Waterloo, Wellington or York."
Here's the thing about "target" shooting on crown land: if you do it without a hunting license, you can be charged with poaching. You may attempt to convince the conservation officer that you're only shooting at those purty paper targets and gongs you set up down there, but you're totally at his mercy as to whether he chooses to believe you or not. If you do it with a hunting license, you're covered... unless it's a small game license during big game season (essentially Sep to Dec, depends on the WMU) and you use something bigger than a .22.
About the clothes (p.25):
"all licensed hunters, including bow hunters and falconers, hunting during a gun season for deer, elk, or moose, are required to wear hunter orange. This requirement does not apply to persons who are hunting migratory game birds, except woodcock. In addition, all licensed black bear hunters hunting during the open season for black bear are required to wear hunter orange except when in a tree stand. Where there is a gun season for moose, elk, or deer concurrent with an open black bear season, then the only persons exempted from wearing hunter orange are migratory game bird hunters as indicated above."
Hope this helped!
Rod: That's one sweeeeet looking little lever action! Short, light, uses a box magazine, can take a scope and available in many calibers! A little costly, but heck... may well be worth it.
