Health Care Directive Signing and Witnessing Rules in Saskatchewan

Saskatchewan's signing rules for a health care directive are more straightforward than most people expect — but the exceptions trip up enough families that it's worth walking through the details, especially because the rules for a health care directive are completely different from those for an Enduring Power of Attorney.

The Default: No Witnesses Needed

If you sign your health care directive yourself — in your own handwriting — you do not need any witnesses. The document is legally valid the moment you sign and date it.

This applies whether the directive is handwritten or typed. The key is that you physically sign it yourself. No lawyer is required, no notary, no witnesses. Saskatchewan deliberately simplified this requirement under The Health Care Directives and Substitute Health Care Decision Makers Act, 2015 to remove barriers to getting a directive in place.

The Exception: Directed Signing

If the maker is physically unable to sign — due to paralysis, a stroke, advanced illness, or any physical limitation — another person can sign the directive on the maker's behalf. This is called directed signing, and it triggers stricter rules:

• The person signing must do so in the maker's presence and at the maker's direction
• One independent witness must be present and must also sign the document
• Neither the proxy named in the directive nor the proxy's spouse can serve as the witness or the person signing on behalf

That last restriction is critical. If your husband is your proxy and your sister-in-law (his spouse) witnesses the directed signing, the witnessing is invalid. Similarly, if your proxy is the one physically signing the document for you, the entire arrangement fails.

Why People Get Confused: The POA Comparison

The confusion almost always comes from mixing up health care directive rules with Enduring Power of Attorney rules. An Enduring POA in Saskatchewan always requires witnesses, with no exceptions:

Because many Saskatchewan residents draft both documents at the same time, they assume the stricter POA rules apply to both. They recruit two witnesses and have a lawyer sign off on everything, which is unnecessary for the health care directive (though not harmful). The real danger runs the other way: someone assumes the simpler directive rules apply to their POA, has it witnessed by a single family member, and discovers too late that the POA is invalid when a bank or care home rejects it.

What Counts as a Valid Signature

The Act requires the directive to be "in writing" and "signed." Handwritten signatures are clearly valid. The more common question is whether a typed name or an electronic signature qualifies.

Saskatchewan has enacted provisions allowing remote witnessing of Wills and Enduring POAs via video technology (Zoom, Teams), provided at least one witness is a licensed Saskatchewan lawyer. Health care directives don't need this protocol because a self-signed directive is valid without witnesses — there's nothing to remotely witness.

For practical purposes: sign the document by hand. If you're drafting a typed directive, print it and add a handwritten signature. It removes any ambiguity.

Common Mistakes

Recruiting unnecessary witnesses for a self-signed directive. Not harmful, but often delays the process because people hunt for "eligible" witnesses before realizing they don't need any.

Having the proxy witness a directed signing. The statute explicitly bars the proxy and the proxy's spouse from serving as witness when someone else signs on the maker's behalf. This is the most common substantive error.

Forgetting to date the document. The signature alone isn't enough — the directive must be dated. An undated directive creates problems when a maker has multiple versions, and medical teams can't determine which is most recent.

Assuming the directive needs to be filed somewhere to be valid. Unlike court documents or land title registrations, a health care directive is valid the moment it's signed. Uploading it to MySaskHealthRecord is highly recommended for accessibility, but the upload doesn't create validity — the signature does.

Next Steps

Sign your directive, date it, and then focus on making it accessible: upload to MySaskHealthRecord, place a copy in the SHA Yellow Sleeve on your fridge, and give copies to your proxy and your family doctor. The Saskatchewan Advance Directive & Living Will Kit includes signing checklists and witness eligibility flowcharts so you can verify compliance before your directive is needed in an emergency.
