Can a registration number of a car identify the owner ?

[Jan Lilliesköld]

We are searching information that can ensure the identity of a man.

The attached pictures are supposed to be of the man searched for,
standing in front of his cars.

It is probably in Canada in the 1950th ?

Sorry to say isn't the resolution too good,
but can anyone say if this can have been a canadian registration number ?

The second question is if there is any way to identify who owned these cars ?
Are there any registers for this ?

Intentionally doesn't I give you the name here.
