 In each province but Newfoundland and Labrador, motorists are given the option of extra-cost "vanity plates" (also known as "personalized" or "prestige" plates), which are licence plates with a custom serial (sequence of letters and/or numbers).Generally vanity plates are not permitted to have profane or obscene messages on them, although standards vary widely among issuing jurisdictions as to what constitutes an unacceptable message.In some jurisdictions, vehicle owners may also pay extra for "specialty plates".
