Read official source✓Plain English
The driver carries the original or a copy of the CVOR certificate, or the original or a copy of the lease for a leased vehicle (HTA s.16(3)(a)). CVOR references are professional fleet ID, not an Ontario display mandate. If you do letter the truck (or display USDOT for US trips), these are common specs.
