Highly unlikely.
They’re struggling to collect even the handful already turned in through existing channels.
Their own estimates on how many newly prohibited firearms are out there have been low (figures like 150,000 have been floated). Do they really want to go looking for more? The budget is capped, and there is little appetite from Provinces and Police for such endeavors.
Going back through sales records for formerly NR firearms would mean store-by-store records, lawful access, paperwork, and warrants where required. That’s not a scalable enforcement model. And really, why bother? - they know we’re not the problem and they’ll have their stunt for votes already.
Far more likely a firearm comes onto the radar some other way first - call for service, complaint, domestic, border issue, warrant on something unrelated, etc. Then enforcement follows from there.
And trying to prove present possession/location from an old sales record alone is weak. Maybe part of a bigger picture, sure, but not much by itself.
That’s usually how these things work in the real world of law enforcement. My guess is illegal guns will show up, but they’ll show up with wads of cash, drugs, and by people known to Police - just as they always have.
