To obtain a custom Ontario license plate, you must adhere to several requirements. First, your chosen plate combination must comply with the province’s guidelines, ensuring it doesn’t contain any offensive language or violate trademarked phrases. Additionally, there’s a character limit to consider, typically ranging from 2 to 8 characters, depending on the type of vehicle and plate style. You’ll need to pay the required fee for the custom plate, which may vary depending on your selection and whether it’s a new plate or a replacement. Finally, you must ensure your vehicle’s registration is up to date and that you have all necessary documentation to complete the application process through ServiceOntario or an authorized provider.
