OTTAWA — Public Safety Minister Gary Anandasangaree said he doesn’t foresee logistical challenges in gathering up banned firearms through a federal buyback program, despite the refusal of several provinces and police forces to help. The government says anyone in possession of a banned firearm or device after the amnesty period will be breaking the law and could face criminal prosecution. Firearm rights advocates and the federal Conservatives have called it a poor use of taxpayer dollars targeted at law-abiding gun owners. Alberta is using the province’s Sovereignty Act to counter the federal program, while Saskatchewan says amendments to the province’s Firearms Act will help ensure affected gun owners receive fair compensation. Gun control groups say an owner who turns in a banned gun for compensation could then use the money to buy an SKS, making the compensation program a failure.
