Advance care planning is the process of thinking through and writing down what matters to you about your medical care, so that if you ever can’t speak for yourself, the people making decisions on your behalf actually know what you would have wanted.
That’s it. It isn’t a single form. It isn’t a one-time signature. It’s a set of clear answers to questions that families otherwise have to guess at under enormous pressure.
What advance care planning actually involves
A complete advance care plan usually does three things.
It names who decides. If you can’t communicate, someone has to make medical decisions for you. Advance care planning lets you choose that person deliberately, rather than leaving it to a default order set by provincial law. Depending on where you live, that named person is called a substitute decision-maker, an attorney for personal care, an agent, or a representative.
It records what you value. This is the part most forms skip and the part that matters most. Not just “resuscitate me” or “don’t,” but the deeper questions underneath. What does a good quality of life mean to you? At what point would aggressive treatment stop being worth it? What would you be willing to endure for a chance at recovery, and what would you not? These answers are what let a decision-maker act with confidence.
It documents your wishes in a usable form. A plan only works if it can be found and understood when it’s needed. That means clear language, shared with the right people, and, where the law requires it, properly witnessed and signed.
What advance care planning is not
A lot of the confusion in this area comes from words that sound similar but do very different things.
It’s not a will. A will deals with your property and money after you die. Advance care planning deals with your medical care while you’re alive but unable to speak for yourself. It’s a different document for a different moment and a different purpose entirely.
It’s not a DNR. A “Do Not Resuscitate” order is a specific medical instruction, usually signed with a doctor, about one narrow scenario: whether to attempt CPR if your heart stops. Advance care planning is much broader. It’s the values and the decision-maker behind decisions like that one, not the single instruction itself.
It’s not only a power of attorney. A power of attorney for personal care (the name varies by province) is the legal instrument that names your decision-maker. It’s an important part of advance care planning, but naming someone isn’t the same as telling them what you’d want. A decision-maker with no guidance is still left guessing.
It’s not just for the elderly or the dying. The decisions advance care planning prepares for are most often caused by sudden events, such as a car accident, a stroke, or a serious infection, and those can happen at any age. The people who most regret not having a plan are frequently the families of younger adults no one expected to need one.
Why it matters
Fewer than one in five Canadians (17%) have an advance care plan, and many of the plans that do exist fail when they’re finally tested. They’re lost, outdated, or silent on the questions that actually come up.
When there’s no plan, the cost doesn’t disappear. It lands on the people closest to you, at the hardest moment, in the form of impossible decisions made without any idea of what you would have chosen. Families carry that uncertainty for years.
Advance care planning is, at its heart, a gift to the people who will have to decide. It replaces “I think this is what they would have wanted” with “I know.”
Where to start
You don’t need a lawyer to begin, and you don’t need to have all the answers at once. Advance care planning is a conversation with yourself and the people you trust, captured in a form that holds up when it counts.
Tiller guides you through that conversation step by step. It helps you think through your values, choose your decision-maker, and produce a clear document built to your province’s requirements. It’s designed for exactly the questions that paper forms leave blank.
Tiller produces documents formatted to provincial requirements. Whether a document is legally valid also depends on the witnessing and signing steps you complete. We’ll walk you through those too.
