Replying to Am I Legal??

Ok, so my 19th birthday is tommorow, and I am in Ontario so 19 is our legal drinking age. I am wondering if I was to try to get into a bar after midnight would I be legal or would I be told to come back tommorow??

I have been told by some that I wouldnt't be legal but I asked a cop and he said I would be and he doesn't see why I wouldnt be allowed.

Has anyone here tried this at all, or know of anyone who has and how did it work out??

Thanks alot
