Depends on the status of the vehicle according to the ownership papers. On the top of the ownership, it should show the code "MCL - FIT" (i.e. Motorcycle - Fit) before MTO will consider issuing a temporary plate for road use (10 days limit). If the ownership says "MCL - UNF" (i.e. Motorcycle - Unfit), then MTO will not issue a temporary license under any circumstances before a safety certificate is issued; and you'll have to transport the motorcycle to the mechanic's who will safety the vehicle, not ride it there.
