I'd imagine they will need to classify them as "motor vehicles" which will require users to provide proof of a driver's license with motorcycle endorsement to use them.
Not really ideal for most casual users.
E-bikes in Canada don't require a license and are not classified as "motor vehicles". Only real requirement for the rider is to be 16+. More info over here:
I rode a Jump a few hours ago. The electric part of the ride is minimal.
It's there to help with hills and similarly harder parts of a ride, but they won't enable you to ride faster than an experienced rider on a light road bike.
It appears by staying under 20 MPH they can avoid this.
