Canadian licence plate designs and serial formats

In Canada, licence plate numbers are usually assigned in ascending order, beginning with a starting point such as AAA-001. Thus, someone familiar with the sequence can determine roughly when the licence plate was issued. After Ontario's transition to an ABCD-123 format in 1997, plates were issued in ascending order starting with AAAA-001. It took close to ten years to exhaust the supply of plate numbers with A as the first digit. In late 2006, plates with B as the first digit were assigned, and have continued from there sequentially. Plates with C as the first digit have been spotted in Ottawa and Toronto as of August 2016.
