So for those who do not know, when a replacement plate is requested Service Ontario has a form that is to be filled by a Police Officer (SO needs that form to release new plates).
If the plate was stolen in one municipality and it was reported there, the Service Ontario form can be signed by a police office from a different jurisdiction.
Some police stations might have the form already rubber stamped for pickup (this saves you a trip to Service Ontario).
Such form has to be brought to Service Ontario and a full price for the plate is to be paid (no discount for stolen replacement).
If I find the person who took my plates, I will kindly request the replacement cost ($25 or so) back!
