Consent to Treatment: The Legal Standard in Canada
0 of 6

A regional long-term care home in central Alberta admitted an 81-year-old woman following a series of strokes that left her with significant cognitive impairment and limited mobility on her left side. The admission occurred 14 months ago, and the resident initially settled into the facility without significant difficulty. Her daughter, who lives in a neighbouring city approximately 90 kilometres away, signed the admission paperwork and has remained the primary family contact throughout the placement. No personal directive was located among the resident's belongings at admission, and the intake documentation notes only that the daughter "will make decisions" without specifying under what legal authority she would do so.

Over the past 3 months, the resident's cognitive state has fluctuated considerably. On some days she engages in coherent conversation with staff, expresses clear preferences about her meals and daily routine, and demonstrates awareness of her surroundings. On other days she does not recognize familiar caregivers, becomes agitated when approached for routine care, and has on 2 occasions physically resisted assistance with bathing. The care team has not conducted a formal capacity assessment at any point since admission, relying instead on informal observations documented inconsistently across nursing notes.

The immediate question arose when the resident developed a persistent skin ulcer on her lower left leg. The attending physician recommended a debridement procedure to prevent further tissue damage and potential infection. When a nurse approached the resident to explain the procedure and obtain consent, the resident stated clearly that she did not want "anyone cutting on her" and asked to be left alone. The nurse documented this refusal in the progress notes but did not record any assessment of whether the resident understood the nature of the proposed treatment, its risks, or the consequences of refusing it.

The daughter, when contacted by telephone the following day, expressed frustration that staff had not simply proceeded with the treatment. She insisted that her mother "doesn't know what she's saying half the time" and directed the care home to perform the debridement. The facility administrator, uncertain how to proceed, instructed staff to delay the procedure pending further review. The wound has since worsened, and the physician has now documented that the ulcer presents a risk of serious infection if left untreated for more than 7 to 10 additional days.

The care home's existing consent documentation for this resident consists of a single general consent form signed at admission, which authorizes "routine nursing care and medical treatment as required." The form does not address capacity, does not identify a substitute decision-maker by legal designation, and does not reference any personal directive or guardianship order. No capacity assessment, formal or informal, appears anywhere in the resident's chart.

Capacity Assessment: When and How It Is Done

Capacity assessment sits at the heart of consent law in Canada because it determines whether a person can make their own treatment decisions. The legal authority to accept or refuse healthcare flows directly from the finding that a person possesses the requisite mental capacity to understand and appreciate the consequences of that decision. When capacity is present, the individual's choice must be respected regardless of whether others agree with it. When capacity is absent, decision-making shifts to a substitute decision-maker who must act in accordance with the person's prior expressed wishes or best interests. The stakes of getting this assessment wrong run in both directions. Treating a capable person without their consent constitutes battery at common law and violates their constitutional rights to security of the person and bodily autonomy. Conversely, accepting a refusal of treatment from a person who lacks capacity to make that decision may result in preventable harm or death. Professionals working in controlled care environments must understand both when capacity assessment is required and how it should be conducted to meet the legal standard that applies across Canadian jurisdictions.

The legal framework governing capacity assessment draws from multiple sources including provincial health care consent legislation, mental health statutes, health professions regulation, and common law principles that apply throughout Canada except where modified by Quebec's civil law system. In common law provinces, the test for capacity has been articulated through judicial decisions and subsequently codified in legislation such as Ontario's Health Care Consent Act, British Columbia's Health Care (Consent) and Care Facility (Admission) Act, Alberta's Personal Directives Act, and Saskatchewan's Health Care Directives and Substitute Health Care Decision Makers Act. While the specific language varies across jurisdictions, the core elements remain consistent. A person is capable with respect to a treatment decision if they can understand the information relevant to making the decision and appreciate the reasonably foreseeable consequences of making or not making that decision. This two-part test requires both cognitive understanding of the facts and the ability to apply that information to one's own situation. As of the date of authorship, these legislative frameworks maintain this fundamental approach while varying in procedural details regarding who may conduct assessments and what review mechanisms exist.
