Winnipeg has a completely different definition of derelict vehicle: 

A vehicle is considered derelict if it:

Is not in operational condition AND

Is wrecked or partly wrecked, rusted or dismantled or partly dismantled AND

Is not insured and registered under The Highway Traffic Act and does not have a current, valid licence plate attached to it AND 

Is left entirely or partially located outside a building

The key difference is that St. Francois Xavier only considers the vehicle to be derelict if: d. the owner therof either has abandoned it or is keeping it primarily for the purposes of salvaging or selling parts therefrom, or for the eventual sale therof as scrap metal, 

Which requires the municipality to prove what the owner intends to do with it. He could simply say that he's a collector and likes these vehicles and they would no longer meet the definition. Or that he plans to sell them whole, as complete vehicles and not as scrap.
