Guardianship Documents in Ontario: Complete Guide

Documents that may help:

Note: Temporary arrangements are not court-ordered but can be helpful for dealing with schools, doctors, and other institutions.

Permanent Guardianship Through Will

Parents can name a guardian for their children in their will:

• Takes effect only after both parents' death
• Should include backup guardian
• Will should be properly witnessed and stored

Notarization of wills: While not legally required in Ontario, notarized wills or certified copies may be useful for probate.

Court-Appointed Guardianship

In some situations, a court must appoint a guardian:

Court documents typically require affidavits.

Guardianship of Incapable Adults

When adults cannot manage their own affairs due to mental incapacity, there are several pathways to guardianship.

Power of Attorney (Prevents Need for Guardianship)

If someone has properly executed Powers of Attorney before becoming incapable:

• Power of Attorney for Property — For financial/property decisions
• Power of Attorney for Personal Care — For health/personal decisions

This is the preferred approach — planning ahead avoids court involvement.

Court-Appointed Guardian of Property

When someone is incapable and has no Power of Attorney:

Required documents include:

Statutory Guardian of Property

The Public Guardian and Trustee automatically becomes guardian when:

• Someone is found incapable during a capacity assessment
• No Power of Attorney exists
• No family/friend applies

Family can then apply to replace the statutory guardian.

Guardian of the Person

Similar to guardian of property, but for personal decisions:

Required Affidavits for Guardianship

Affidavits are sworn statements used extensively in guardianship matters:

Affidavit in Support of Application

Your main statement explaining:

• Your relationship to the person
• Why guardianship is needed
• Your suitability as guardian
• Your plans for the person/property

Affidavit of Service

Proves that required people were notified of the application:

• The incapable person
• Family members
• The Public Guardian and Trustee
• Others as required

Affidavits from Collateral Sources

Statements from others supporting the application:

• Family members
• Friends
• Healthcare providers
• Financial institutions

Affidavit of Assets and Liabilities

Details the incapable person's:

• Assets
• Debts
• Income
• Expenses

Capacity Assessments

A capacity assessment by a designated assessor is usually required:

What It Includes

• Interviews with the person
• Medical records review
• Assessment of decision-making ability
• Written report

Using the Assessment

• Original goes to court
• Certified copies for other purposes
• May need to be updated periodically

Documents for Ongoing Guardianship

Once appointed as guardian, you'll need ongoing documentation:

For Guardian of Property

For Guardian of the Person

Temporary Substitute Decision-Making

For emergency situations, hospitals and care facilities may need:

Emergency Consent

Immediate family members can sometimes consent to emergency treatment without formal guardianship.

Section 20 Notices

When someone is found incapable of managing property during a capacity assessment, notices must be given.

Affidavits of service may be required.

Guardianship for Children Traveling Internationally

When children travel with guardians (not parents):

Travel Documentation

These should always be notarized for international travel.

What to Include

• Child's full information
• Guardian's full information
• Parents' contact information
• Travel dates and destinations
• Emergency medical authorization

Custody vs. Guardianship

These terms are often confused:

Custody is governed by family law; guardianship is governed by different legislation.

International Considerations

Foreign Guardianship in Canada

If you have guardianship from another country:

• May need recognition in Canada
• Certified copies of foreign orders
• Affidavits about foreign proceedings
• Authentication/apostille of foreign documents

Canadian Guardianship Used Abroad

If using Canadian guardianship documents internationally:

• Certified copies of court orders
• Authentication chain (notary → provincial → federal → embassy)
• Or apostille for Hague countries

See our guide on apostille vs. notarization.

Common Guardianship Mistakes

❌ Not Planning Ahead

The best approach is to have Powers of Attorney in place before incapacity. This avoids:

• Court costs
• Delays
• Family disputes
• Public Guardian involvement

❌ Incomplete Applications

Guardianship applications require extensive documentation. Missing documents cause delays.

❌ Not Serving All Required Parties

Court rules require notice to many people. Improper service can void the process.

❌ Not Understanding Ongoing Obligations

Guardians have legal duties:

• Acting in best interests
• Keeping records
• Filing accounts
• Getting court approval for major decisions

❌ Confusing Guardianship with POA

Power of Attorney only works if signed before incapacity. After incapacity, guardianship may be needed.

Costs Associated with Guardianship

Court Process Costs

Notarization Costs
