If you're applying to become someone's guardian of property in Ontario, you can't simply ask the court to trust that you'll handle things responsibly. You have to show your work — in a document called a management plan, filed as part of the application.

For many proposed guardians, this is the most time-consuming part of the whole process, and also the part most likely to get sent back for revisions if it's incomplete. Here's what it actually needs to do.

What a Management Plan Is, and Why the Court Requires One

A management plan is a detailed written proposal setting out how you intend to manage the incapable person's property if you're appointed. Because guardianship of property hands one person significant control over another person's finances, Ontario courts require concrete evidence of a sensible plan before granting that authority — not just an assurance that you'll figure it out along the way.

Think of it less like a formality and more like a business case: you're asking the court to trust you with someone else's financial life, and the plan is how you demonstrate you've actually thought it through.

What It Generally Needs to Cover

Who Has to Prepare It

The person applying to be guardian generally prepares the management plan themselves, though it's common — and advisable — to do this with a lawyer's help, since the plan needs to align with what the court and, in many cases, the Public Guardian and Trustee's office expect to see. A vague or incomplete plan is one of the more common reasons an application gets delayed.

What Happens After You're Appointed

The management plan isn't a document you file once and forget. If you're appointed guardian of property, you're generally expected to actually manage the person's property consistently with the plan you proposed, and you can be required to formally "pass your accounts" — essentially, prove to the court that your actual management matched what you said you'd do. Significant, unexplained deviation from the plan can raise questions in that process.

Common Mistakes That Delay Approval

Frequently asked questions

Do I need a lawyer to prepare a management plan?

It isn't strictly mandatory, but a management plan is a technical document that the court and, often, the Public Guardian and Trustee's office will scrutinize closely — most proposed guardians find it worthwhile to have a lawyer involved, at minimum to review it before filing.

What if I don't know the exact value of all the person's assets?

Reasonable estimates, clearly identified as estimates, are generally acceptable for a first filing — but you should be prepared to gather more precise figures as part of preparing the plan, since vague guessing throughout the document is a common reason plans get questioned.

Does the management plan ever need to be updated after I'm appointed?

Circumstances change — new income, a property sale, changing care needs — and a significant shift from what the plan described can be relevant when you're later required to account for your management. Keep records of any major changes as they happen.

Is a management plan required for guardianship of the person, too?

No. A management plan is specific to guardianship of property. Guardianship of the person involves different supporting material focused on personal care decisions rather than financial management.
