Losing an adult child is devastating. Losing access to your grandchildren after that death can feel like a second, compounding loss — especially when the surviving parent begins to limit or cut off contact entirely.

In Ontario, grandparents do not lose their right to seek contact simply because their son or daughter has died. The Children's Law Reform Act still allows grandparents to apply for contact or parenting time, and courts dealing with these post-death scenarios are alert to the particular harm that comes from severing a child's ties to their deceased parent's family.

Why This Situation Arises

When a parent dies, the surviving parent becomes the child's sole legal custodian — they have full decision-making authority over the child's life, including who the child sees and spends time with. This is the correct legal default, and it protects parental autonomy.

But this authority can be misused. Grief can curdle into conflict, old resentments can surface, and a surviving parent may — consciously or not — begin to limit the child's contact with the deceased parent's family.

From a child's perspective, this can be deeply harmful. Research consistently shows that children benefit from maintaining connections to both sides of their family, and that losing contact with a deceased parent's relatives can compound the child's grief and erode their sense of identity.

The Legal Framework

Any Person May Apply for Contact

Under Ontario's Children's Law Reform Act (CLRA), any person — including a grandparent — may apply to the court for an order granting them contact with or parenting time with a child. The death of their parent does not remove a grandparent from the category of persons who may apply.

The Best Interests Standard

Courts assess grandparent contact applications using the best interests of the child test. In the context of a deceased parent, courts frequently give weight to:

The Surviving Parent's Rights

The surviving parent is a fit parent with the right to make decisions about the child's care. Courts do not override those decisions lightly. A grandparent must demonstrate that contact genuinely serves the child's best interests — not just that it is emotionally important to the grandparents themselves.

When Courts Have Ordered Grandparent Contact Post-Death

While every case turns on its own facts, courts have been more willing to order grandparent contact where:

Courts have also been cautious. Where the grandparent's application seems designed to re-litigate past conflicts with the surviving parent, or where the grandparent has expressed hostility toward the surviving parent in front of the child, courts may limit the order or deny it.

What You Can Do Now

Preserve the Relationship Informally If Possible

Before filing a court application, try to maintain the relationship through low-key means: birthday cards, casual messages to the surviving parent, offers of support. An escalation to court can sometimes entrench the conflict further.

Write a Thoughtful Letter

A well-drafted, non-threatening letter from your lawyer to the surviving parent — acknowledging their grief and authority while expressing the importance of the child maintaining ties to their parent's family — can sometimes open a door.

Consider Mediation

A family mediator who has experience with post-death situations can sometimes help surviving parents and grandparents reach an agreement without court. This is generally better for the child than adversarial litigation.

Apply to the Court If Necessary

If informal efforts fail, a court application is your legal right. Document your prior relationship with the grandchild carefully — photos, communications, descriptions of regular activities and gatherings — to support your case.

Parenting Time vs. Contact in This Context

Most grandparent applications after a parent's death seek contact — regularly scheduled visits, video calls, holiday time. This is distinct from parenting time, which implies a more significant co-parenting role.

Unless the grandparent was already the primary caregiver or unless the surviving parent is also unable to care for the child, decision-making responsibility applications are less common in this context. The more measured ask for regular contact is both more realistic and more likely to be granted.

Frequently asked questions

Can the surviving parent move away and take the child with them to cut off contact?

A parent has the right to relocate, but relocation does not eliminate a grandparent's right to apply for contact, and a court can order contact arrangements that work across distance — scheduled video calls, holiday travel, summer visits.

If my son had a will, can he have designated me as a guardian?

A parent can name a guardian in their will, but a will designation alone does not create binding legal rights. The court must confirm the guardianship, and the surviving biological parent's rights take precedence unless they are unfit or unavailable. Wills can express wishes, but courts make the final determination.

Does it matter whether my son and the surviving parent were married or common-law?

No. The marriage status of the parents does not affect a grandparent's right to apply for contact with a grandchild. Your right to apply flows from your relationship with the child, not from the parents' legal status.

How soon after a parent's death should I apply if my access is being cut off?

There is no strict deadline, but acting sooner is generally better. Courts are alert to applications that come years after the fact without explanation. If contact is abruptly terminated, get legal advice within the first few months.
