Under section 32(1) of the Highway Traffic Act, no person shall drive a motor vehicle on a highway unless the motor vehicle is within a class of motor vehicles in respect of which the person holds a driver's licence issued to him or her under this Act. There is a set fine of $260.00. There is no jail time, but your future insurance will most likely be impacted.
It is also an offence under section 53 of the Highway Traffic Act to drive while one's driver's licence is suspended. This offence carries a more serious penalty.
For a first offence: a fine of not less than $1000, but not more than $5000
For each subsequent offence: a fine of not less than $2000, but not more than $5000;
OR to a term of imprisonment of not more than six months;
OR to both a term of imprisonment AND a fine (the minimum fine varying based on whether it is a first or subsequent offence)
