These documents can protect or exploit — the difference lies in the systems that surround them
Every lawyer who has drafted a Power of Attorney (POA) knows what it's designed to do. Far fewer have had to reckon with how thoroughly it can fail — not because of bad drafting, but because of what happens after the document leaves the office.
When surrounded by the right safeguards, POAs are among the most protective instruments in estate planning. When they aren't, they can become something else entirely: a mechanism for exploitation and abuse, and a liability for every institution asked to rely on them.
Across Canada, serious structural gaps in how POAs are executed, tracked, and verified have gone largely unaddressed. An aging population, rising cognitive vulnerability, rapidly evolving technology, and heightened expectations of governance and accountability have made those gaps more consequential than ever.
Nathan Spaling, founder of POARegistry.ca and the Canadian Centre for Decision-Making Capacity, has spent years mapping where the current system breaks down.
“I’m among a growing coalition of professionals across Canada that share a common goal: preventing the misuse of substitute decision-making documents while preserving autonomy,” he says. “My work is far from a criticism of current practice; it's an evolution of practice procedures.”
Invisible incapacity, visible risk
The most basic assumption underlying many planning frameworks is that people will recognize when they are no longer able to manage their own affairs. In practice, that assumption often fails. As people age, cognitive decline, illness, injury, and vulnerability erode self-awareness. The person doesn’t feel incapacitated, they feel like themselves.
One of the highest-risk scenarios is a new POA signed at or near this point of incapacity. An older adult may be encouraged to sign a fresh document through a different lawyer or an online platform — effectively revoking the authority of anything established earlier without notice, sidelining safeguards put in place when the grantor had capacity.
In those situations, Spaling says, the POA becomes “more powerful than a blank cheque.” It confers near-total control over finances, housing, health-care decisions, and access to personal information, all while looking entirely legitimate. When capacity is questionable or the person is subject to undue influence, the resulting POA is a direct threat to the grantor's autonomy and quality of life. It’s also a risk that extends to every organization asked to honour the document.
When institutions must guess
That individual-level risk is intensified by how the law treats POAs compared with other planning tools. Competing wills go to court, for example, and executors act only after judicial confirmation. With POAs, there’s no automatic process. The burden of deciding whether the document in front of them is a current, valid authority or a vehicle for misuse lands on individuals at places like banks, insurers, and health-care providers.
That’s an extraordinary responsibility to place on frontline institutions, Spaling notes, especially without the benefit of a shared source of truth. Many businesses don’t have clear procedures to assess competing POAs, access to prior versions, the authority to notify previously appointed attorneys, or the ability to investigate without breaching privacy laws.
“As a result, good faith decisions are made with incomplete information while risk is shifted downstream,” he says. “These institutions are exposed to reputational, legal, and regulatory harm.”
To illustrate the mismatch, Spaling points to a simple comparison: if driver's licences were created from downloadable templates with no identity verification, no central registry, and no version control, the public would never accept it. Yet a substitute decision-making document created under those conditions can sell someone’s car and the house it's parked at — and access all the proceeds.
Technology has magnified that risk. With widespread access to AI tools and document templates, POAs can be altered — or entirely fabricated — in minutes. Authenticity, already a challenge in paper-based systems, is more difficult than ever to assess.
“The procedural safeguards around one of the most important documents in a person's life are now weaker than ever, while the consequences of misuse are greater than ever,” Spaling warns. “This creates a troubling reality and the issue isn’t recklessness, it’s the fact that the system is siloed. It was never designed for modern longevity, complexity, or vulnerability.”
Registration as shared infrastructure
Spaling's answer is not to fundamentally change the work lawyers do, or to overhaul their drafting platforms and storage methods. He does, however, want to create better infrastructure. That was the purpose behind the development of POARegistry.ca.
A localized hub for registration, the site was designed to bolster the professional work happening behind the scenes, not compete with it. It’s akin to land registries in that they’re not a substitute for real estate lawyers. They simply make the transactions those lawyers handle safer.
By registering a POA, grantors and their advisers can improve visibility across institutions, reduce dependence on informal copies, and support more defensible decision-making. Registration can expose revoked or competing documents earlier and bring potential conflicts to light before harm occurs.
The registry also supports fractional validation — a process that enables institutions to assess the legitimacy of a document against a known reference point, without requiring full legal review every time.
“I wanted to address one core problem: the absence of a trusted, neutral reference point confirming which authority exists and is being relied upon,” Spaling explains. “Registration changes the risk equation.”
The registry was shaped by input from a collaborative coalition including drafting professionals, trust companies, financial institutions, professional substitute decision-makers, digital estate-planning platforms, secure storage providers, and compliance teams. For Spaling, this reflects a core truth about his work: it’s not about mistrust. It’s about recognizing that such formidable documents require equally strong supports.
Turning power into protection
For legal professionals, the question is a direct one: are your current procedures equipped to catch misuse — or are they relying on incomplete information and hoping for the best? Can the institutions your clients interact with identify a revoked or competing POA before acting on it? And if not, what would it take to close that gap?
Tools like POARegistry.ca are part of that answer. Engage with them not to supplant professional judgment, but to enhance it.
“Trust isn’t maximized by acting alone; it’s built through shared systems of accountability,” Spaling says. “Together, we can ensure that the most powerful document a person signs is one that truly protects them — when they need it most.”
