The Highway Safety Code (HSC) is clear: wearing a seat belt correctly is mandatory. If you fail to do so, you face a fine and 3 demerit points on your driving record.
“Every person [...] must, while in a moving road vehicle, wear, properly fastened, the seat belt with which his [or her] seat is equipped.” (s. 396 HSC)
“No person may either effect or cause the removal, alteration or putting out of service of a seat belt with which the seats of a road vehicle are equipped under the Motor Vehicle Safety Act (Statutes of Canada, 1993, chapter 16).” (s. 250 HSC)
Wearing a seat belt is not mandatory if you are backing up, but only for the time it takes to do so.
If you have an exceptional medical condition, you can apply to be exempt from wearing a seat belt. Your attending physician must provide a detailed report demonstrating that you have an exceptional medical condition for which there is no other suitable solution, such as using a seat belt extension.
You are responsible for ensuring that all your passengers under 16 years of age buckle up. If any of your passengers under 16 are not buckled up, you face:
The maximum number of passengers, regardless of their age, is equal to the number of places equipped with a seat belt installed by the manufacturer.
In a vehicle, children whose sitting height is less than 63 cm (measured from the seat to the top of the head) must be secured in an appropriate car seat that is adapted to their weight and height. If you fail to buckle a child into an appropriate seat, you face:
It is very important to first check whether the child is tall enough to use a regular seat belt. To do so, buckle the child into the back seat. The child is tall enough if:
The law doesn’t change. Passengers in a taxi must always buckle up.
It is the adult accompanying the child, and not the taxi driver, who faces a fine and demerit points.
When riding in a taxi, if there are no child safety seats, children must wear seat belts, except if they are too young to maintain an upright position on their own. In the latter case, you should first buckle your seat belt, and then hold the child in your arms. Do not buckle the child in with you because your weight could crush him or her in the event of a collision or sudden braking.
On the majority of public roads, including roads located within town and city limits, taxi drivers are exempt from wearing seat belts when they are on duty.
However, they are required to wear their seat belts when driving on a numbered public road, such as a highway.
While on duty, Uber drivers are required to wear their seat belts at all times. Under no circumstances are Uber drivers exempt from the obligation to wear a seat belt.
