They are gone because we let things slide. Except for the GTA the bush is still there, the country kids are still interested in hunting/guns. We still have room to shoot and plenty of opportunity to do so if people didn't tend to call the police when they heard shots. We have to ask on this forum if we can take ten yr olds hunting with us, or if we can target shoot on Crown Land. Police take the "safe" route and tell us that we should NOT do certain things because they are unsure of the legality.
We also tend to find toy guns at Can Tire that look just like military stuff so us old farts get excited when we see scruffy kids carrying them.
