Taxis do not offer seats for babies.
When children who are less than 145 cm tall or under 9 years of age occupy a seat in a taxi, the law provides an exception to the obligation to secure them in a car seat that is appropriate for their weight and height.
If the child can sit upright, it is mandatory to secure them with a seatbelt.
If the child is too small to sit upright, first secure yourself with your seatbelt and then hold the child in your arms.
More details are available from the SAAQ.
