Hypothetical gun abandonment question

[u/OCTS-Toronto]

I'm curious about the legal aspects of an abandoned restricted or prohibited firearm. If someone owned let's say an ar15 but went to live abroad for a while. They stored it at my house but then never returned. What is the legal status the the firearm? I would not have a registration certificate (in my name) and the owner can't be charged assuming they never return. Would I be in possession of an illegal firearm? If it was turned into the police and then the owner returned many years later would they be charged upon arrival with an offense?

Seems like lots of Canadians are leaving Canada lately and I wonder what happens if they don't live up to all the legislation on the way out.

Hypothetically speaking, unless there was an ATT or transfer, your friend lost it in a boating accident.
