This article examines children’s participation before the courts as a fundamental aspect of their access to justice. Children’s legal minority is an obstacle to their participation in justice and it manifests itself differently in child welfare compared law to family law, for example. Moreover, laws and practices vary across Canada. This different treatment according to jurisdiction and area of law contrasts with international law, which is used to advocate for wide participation rights for children whichever the field. According to the Convention on the Rights of the Child, children should be able to express themselves on all matters that concern them. Based on this, the paper will examine the different ways in which children can be heard in different procedures in Quebec, with a focus on judicial procedures in the areas of child protection and family law. While many provisions are included in the law, these are not precise enough and give way to many contradictions in practice. In the absence of legislative changes, this paper suggests the adoption of guidelines for professionals, which would be inspired by work done at the international level, as well as some practices in other Canadian provinces.
