You need to renew your MTO (Ministry of Transportation Ontario) sticker annually. This sticker, commonly known as a license plate sticker or validation sticker, indicates that your vehicle’s registration is current and valid. Renewal is typically required on or before your vehicle’s registration expiry date, which is usually on the owner’s birthday. Failure to renew on time may result in fines or penalties, and driving with an expired sticker is illegal. However, specific renewal requirements may vary depending on factors such as vehicle type, registration category, and location. It’s essential to check with the MTO or refer to your registration documents for precise renewal information tailored to your situation. There is no cost.
