OP: check to see if you fall into a county that is restricted by the 0.275" ruling.
Not that it really would matter. In my opinion, a 270 Win fits the bill for most hunting conditions in Ontario. Any game, any county. But.......
As this is your first and only rifle, its a good choice so long as you have a good set of shooting techniques and habits. Note that shooting a rifle requires different techniques than shooting a shotgun. If you don't happen to have a good shooting base (this is for you and those who actually know you to judge), then maybe something with a more friendly demeanor would be in order.
This forum has a great many with years of personal experiences and can only offer advice from experiences. Of mine that I can offer, a 270 for a new shooter "may" lead to the development of poor shooting. Symptoms like flinching, eye closing, trigger slapping, etc, are common for new shooters with big cartridges.
I am trying to correct a friends shooting techniques as he started with a 30-06 for his all round rifle. For most experienced shooters, not a hard rifle to handle but for new shooters it "can be" too much.
If you can, try out a couple of rifles with a friend, and shoot 10 or 20 rounds. You should be able to shoot this amount and shoot consistently and accurately in all positions. As this is a hunting rifle, shooting bench is not really representative of the field. But of most important is that you have to be comfortable throughout the shooting.
I started with a 6.5x55 and I introduced it to my friend I am trying to help.
My suggestion would be to get some range time with a variety of cartridges. A box or two of ammo is cheaper than buying the wrong rifle and having to sell it and start over again.
Hope this helps.
