Burrahobbit, please - call me Shane!
Stephen is correct. Non-LEO/non-military cannot own any hi-cap mags. 10 rounds is the maximum.
Be aware of the difference of terms that our government likes to befuzzle us with...prohibited vs. restricted.
Restricted applies to all handguns meeting the Canadaian criteria (not .25, .32 or .380 and barrel longer than 4 1/4", with 10 rd. max. mag.). They are legal to own if you have a valid FAC (Firearms Aquisition Certificate) for ownership/possession of "restricted" weapons.
Prohibited covers all full-auto weapons and hi-cap mags, and the miscellaneous stuff that our government has decided is simply too dangerous for us to own :roll: (ie, snub nose revolvers, or any pistol with a barrel of less than 4 1/4", rifles with barrels less than 16", etc.)
LEO and military CAN get approval to own/purchase the above prohibited items. Civilians and non-LEO cannot.
