I'm going to jump in for one thing only; please don't slag paintball.
Anyone playing paintball lives under the same restrictions, decencies, and common sense.
It only gets a bad reputation because the gear is so readily available, and thus the gene-pool is equally dilute.
Airsoft vs. Paintball is a Soccer vs. Football debate, or even Rugby vs. Football.
On topic; OP, you did a very irresponsible thing.
Please learn more about the history of gun ownership in Canada and take some lessons from a sober and experienced individual before you touch anything resembling a firearm again.
