Same here, Carl. Each province has its own rules.
In this province no plate but a government provided plate is allowed. We now own the plate and can keep it forever - transferring it to new vehicles over the years. That applies to all highway vehicles.
Antique cars are allowed a special plate denoting their antique status. Old motorcycles don't have antique plates - so far.
Our club has been hounding the government for several years to allow the same status for antique motorcycles as the cars have, but they keep dragging their heels.
We have vanity plates for cars and bikes now too.
