What rights do grandparents have in Ontario?

In Ontario, grandparents do not have automatic legal rights to access or custody of their grandchildren. However, they can apply to the court for access or custody if they believe it is in the best interest of the child. The court considers various factors, including the child's relationship with the grandparents and the overall family circumstances. Additionally, grandparents may have rights under the Children's Law Reform Act, which recognizes their role in a child's life.
