What does the warning mean?

Up here in Ontario when you purchase you need to purchase a UVIP (used veh info pkg) before registering it in your name. OR you can use the UVIP to see how many owners the car has had. UVIP contains all prev registered Ontario owners names.
Walk in to our Licensing office with a vin and $20.

Yeah but there's like fifteen people in the whole province and twelve of y'all are related, so there's no real worry there.
