A lot of games will not accept high-cap magazines. Most game will restricts mags to real, low or mid-caps only. Also, I don't know in Ontario, but in Québec, most games are now real capacity only. You can still show up with low and mid-caps, but you will have to load them to the real capacity of the gun you are using.
