In Ontario, license plates must be prominently displayed on both the front and rear of vehicles, with specific guidelines for their appearance. These plates must be clearly visible and free from obstruction, such as dirt or debris. The standard format consists of blue letters and numbers on a white background, although personalized plates and specialty designs are available for an additional fee. Vehicles must have valid and up-to-date plates, renewing annually, with stickers indicating the expiration month. When purchasing a vehicle, it’s necessary to transfer the plates within six days, and when selling a vehicle, plates typically stay with the owner rather than the car. Additionally, drivers should ensure their plates are illuminated at night for easy identification by law enforcement and other drivers.
