Custody vs. Guardianship in Canada: Which One Applies to Your Situation?

When it comes to caring for and making decisions about a child, the legal terms and responsibilities can often feel confusing—especially during a separation, divorce, or other significant life event. Two terms that frequently cause uncertainty are custody and guardianship. While they may seem similar, these concepts carry different legal meanings depending on your province and your family’s circumstances. Understanding the distinction between custody and guardianship is essential for ensuring the best outcomes for your child and making informed decisions about legal responsibilities. Here’s what every parent or caregiver in Canada should know.

Custody: Now Known as Decision-Making Responsibility and Parenting Time

In 2021, Canada’s Divorce Act underwent significant changes to modernize family law terminology. What was traditionally referred to as “custody” is now defined in two parts: decision-making responsibility and parenting time. Decision-making responsibility refers to the right to make important choices about a child’s upbringing, including their education, medical care, religion, and extracurricular activities. Parenting time refers to when a child is in the care of a particular parent.

These updated terms aim to reduce conflict by moving away from the win-lose language of “sole” or “joint custody.” In practice, both parents may share decision-making responsibility or one parent may have it solely, depending on the circumstances and what is deemed to be in the child’s best interest. Parenting time can also be shared or primarily allocated to one parent.

Guardianship: Provincial Jurisdiction and Broader Responsibilities

Guardianship, on the other hand, is governed by provincial and territorial legislation and typically refers to the legal authority to care for a child and manage their affairs when the parents are deceased, unavailable, or unable to fulfill their roles. In provinces like Ontario, the term "guardian" often applies to someone who assumes legal responsibility for a child’s property or well-being, especially outside of the context of divorce or separation.

In British Columbia, for example, guardianship is a more comprehensive term and is automatically shared by both parents unless a court decides otherwise. In contrast, other provinces may separate guardianship into two parts—guardianship of the person and guardianship of the property—with courts or wills specifying who holds which role.

Which One Applies to You?

If you’re a parent going through a divorce or separation, you’re more likely dealing with decision-making responsibility and parenting time, rather than guardianship. These terms are used in court orders, parenting plans, and separation agreements under the federal Divorce Act or applicable provincial legislation. If you’re not a parent but are stepping in to care for a child—such as a grandparent, aunt, uncle, or close family friend—you may be applying for guardianship through a provincial court to obtain the legal authority to care for the child and make decisions on their behalf.

It’s important to understand the legal framework in your specific province, as terminology and procedures can differ. For instance, someone in Ontario applying to make decisions for a minor’s property would need to go through the Office of the Children’s Lawyer, while in Alberta, guardianship involves a separate application process under the Family Law Act.

Legal Implications and Best Interests of the Child

Regardless of whether you're seeking custody or guardianship, Canadian courts always prioritize the best interests of the child. This includes evaluating the child’s emotional and physical needs, the strength of their relationship with each caregiver, the stability of their environment, and their cultural and linguistic heritage. Both custody (decision-making responsibility) and guardianship come with serious legal obligations and are not granted lightly. You’ll be expected to demonstrate that you can provide consistent care, make responsible decisions, and promote the child’s overall well-being.

Final Thoughts

Understanding the difference between custody and guardianship can help you navigate complex family law situations with clarity and confidence. Whether you’re a divorcing parent working out a parenting plan, or a relative stepping in to care for a child, knowing which legal arrangement applies to your case is essential. Since family law can vary significantly from province to province, it’s wise to consult a family lawyer who can advise you based on your unique situation and jurisdiction.
