Advance Care Planning in Canada: A Patchwork of Legal Terms and Practices

Advance care planning (ACP) is the process through which individuals reflect on, discuss, and document their preferences for future health and personal care, particularly for circumstances in which they may no longer be able to make or communicate decisions themselves. While the concepts underpinning ACP are broadly similar across the country, the legal structures, terminology, and documents used to support ACP vary markedly from one province and territory to another. These regional differences that are rooted in distinct legislative frameworks, create challenges for individuals, families, health care providers, and advocates who work to normalize ACP across Canada.  

At its core, ACP involves two related elements: 

1. Advance care planning as a process: conversations and reflection about values and care preferences, and 
2. Advance directives or legal instruments — written documents that may be used to express wishes or appoint someone to make decisions on a person’s behalf. ( 

However, these elements are not defined or regulated identically across the country, and the names and legal effects of the supporting documents change from one jurisdiction to another. 

 

Why Terminology Matters

One of the main challenges surrounding the legal aspects of advance care planning in Canada stems from terminology. Even though terms like advance care plan, advance directive, substitute decision maker, and power of attorney for personal care are widely used, their meaning can shift depending on where a person lives. There is no single federal ACP law, instead, the legislative framework is provincial and territorial, leading to a mosaic of terms and legal forms. 

A national survey of ACP terminology found that: 

• In some provinces, the term advance directive is used in statute; 
• In others, equivalent legislative documents are called personal directives, health care directives, representation agreements, or mandates; 
• The person authorized to make decisions on another’s behalf may be termed an agent, proxy, attorney, mandatary, representative, or simply a substitute decision maker. (spaltc.ca) 

For example: 

• British Columbia uses representation agreements to appoint a representative and may also include advance directives under specific legislation.  
• Alberta’s main document is a personal directive, appointing an agent and setting out wishes.  
• Manitoba and Saskatchewan use health care directives that can include both instructions and appointment of a proxy.  
• Ontario refers to Power of Attorney for Personal Care, appointing an attorney who makes decisions when the person cannot.  
• Québec’s legal instruments include protection mandates and advance medical directives under civil law, reflecting Québec’s unique legal system. 
• Nunavut stands out because it does not currently have legislation for advance directives or formal appointment of a substitute decision maker.  

This terminology variation can confuse not only the public but also professionals from health, legal, and social care sectors, all of whom may use different terms to refer to similar concepts. A 2017 Health Canada-linked glossary project concluded that many Canadians and even experienced professionals find ACP terminology confusing.  

 

Legal Differences and What They Mean in Practice

How Documents Work

In most jurisdictions, ACP documents serve two key purposes: 

1. Instructional directives — outlining what kinds of health care a person does or does not want under particular conditions; and 
2. Proxy directives — naming someone who will make decisions if the person loses capacity.  

However, not all provinces allow both types of directives in the same way. For example: 

• Some provinces allow instructional and proxy directives in one document (e.g., Alberta), 

• Others may be more limited in scope, and 

• A few use separate statutes and forms for each type.  

Moreover, requirements for validity, such as witnessing, formality, and age of the person creating the document, vary between provinces. Because ACP tools do not automatically transfer their legal effects across provincial boundaries, a directive legally valid in one province may not be recognized in another without careful compliance with local rules. 

Consent vs. Planning

In some jurisdictions, and especially under Ontario’s Health Care Consent Act, expressed wishes in an ACP document are not themselves consent, even if they provide important guidance. Instead, the law requires that each specific medical treatment be consented to at the time it is offered, based on current capacity. Documents like advance directives therefore operate as guidance rather than as automatic legal authority for treatment decisions.  

 

Issues Created by Provincial Differences

These differences matter for several reasons, especially when advocating for improved uptake of ACP across Canada.

Public Confusion and Engagement Barriers

Because ACP terminology and legal requirements vary by province, people often find it hard to understand: 

• what they need to do to make valid decisions, 
• how to appoint someone who can act for them, and 
• what legal effects their documents will have, especially if they move or travel between provinces. 

Research shows that even basic awareness of ACP varies across regions, with some Canadians being more engaged in ACP conversations than others. This suggests that inconsistent language and documentation may dampen engagement.

Challenges for Health Care Providers

Health care providers working across provincial borders, or even within systems that draw staff from different parts of the country, may lack confidence in interpreting ACP documents created under another jurisdiction’s terminology. This can result in: 

• inconsistent understanding of who is responsible for decision making, 
• hesitation or errors in following patient wishes, and 
• added stress for families at critical moments. 

ACP Documents Don’t Automatically “Follow You”

Even when ACP documents are properly completed and legally valid, they are not usually integrated into electronic health records in a way that travels with the patient. This means: 

• A person’s ACP document in one province may not be immediately accessible if they receive care in another province or even at a different hospital within the same province. 
• Health care teams may be unaware of existing directives unless the patient or family brings a physical copy, creating delays or inconsistencies in respecting preferences. 
• This “disconnect” can undermine confidence in ACP and leave substitute decision-makers navigating urgent decisions without formal guidance. 

For many Canadians, the lack of a unified system for storing or sharing ACP documents reduces the effectiveness of advance care planning and highlights the need for better provincial and national coordination. 

 

Legal and Ethical Complexity

Aligning ACP documents with local legislation is essential. A person who has completed what they believed to be a valid directive may find that it is not considered legally effective in the province where they receive care, leaving substitute decision-making to statutory hierarchies rather than their chosen representative. 

This can create ethical tensions, for example, when quality of life preferences documented in one region are interpreted differently under the law in another, or are overridden due to procedural defects in documentation.

Advocacy and Policy Work Becomes More Fragmented

For those advocating for greater awareness or system change, including public health entities, non-profits, and legal professionals, the lack of a unified national framework complicates education, policy development, and evaluation of ACP uptake and effectiveness. 

Efforts to craft consistent public messaging must navigate a patchwork of provincial and territorial laws and tailor materials to local terms and legal structures. A national glossary and comparative resources have been proposed to mitigate these barriers, but implementation remains a work in progress.  

 

Conclusion 

Canada’s system for advance care planning reflects the country’s constitutional division of powers — leaving health and personal care law to the provinces and territories. While the core principles of ACP are consistent (capturing values, preferences, and decision-making authority ahead of incapacity), the legal forms, terminology, and portability of documents differ significantly across jurisdictions. (chpca.ca) 

One of the most pressing challenges for individuals, families, and health care providers is that ACP documents often do not “follow you”. They are usually not integrated into electronic health records in a way that makes them accessible across hospitals, health systems, or provincial borders. As a result, even well-prepared advance care plans can be inaccessible at critical moments, creating uncertainty, delays, and stress for substitute decision-makers and care teams. 

For individuals and advocates, these differences underscore the importance of understanding local requirements, seeking professional guidance when necessary, and promoting clear, inclusive public education about ACP. At the same time, there is a wider opportunity for inter-jurisdictional learning and harmonization, including potential solutions such as: 

• Centralized ACP registries that allow directives and proxy appointments to be accessed securely by authorized health care providers; 
• Integration of ACP documents into electronic health records so that preferences travel with patients regardless of where they receive care; and 
• Nationally aligned terminology and resources to reduce confusion and strengthen public confidence in ACP. 

By addressing both the legal variation and the current limitations in document portability, Canada can make advance care planning a more effective, accessible, and trusted tool — empowering people everywhere to ensure their health care preferences are known, respected, and followed.
