Lorraine,
Welcome to Modern Vespa!
If you are going to be riding a scooter in Ontario, you will need a motorcycle licence. There are two different classifications:
M (includes M1 and M2): for full-speed motorcycles.
M with condition L (includes M1 and M2-L): for mopeds and motorized scooters (also called "limited-speed" motorcycles).
The M licence with L condition is for scooters of less than 50cc engine displacement. There are two current Vespa models that fit this condition: The LX50 and the S50. Anything larger than 50cc will require a full M motorcycle licence.
See the Motorcycle Handbook for how to go about getting your licence:
