There has been a long-standing dichotomy of opinions in relation to legal capacity laws which pit paternalism against autonomy. The debate continues and was reflected in the recent international deliberations relating to the article on legal capacity in the CRPD.
The tradition of legal capacity-related laws that restricts people’s right to autonomy was founded on the attitude that there is a need to act for the protection of those who are believed not to be able to care for themselves. It was to be exercised in a manner said to promote the “best interest” of the protected person. The underlying assumption being that the individual’s personal and economic affairs could be better managed by others. However, Canadian laws have progressed substantially in the direction of promoting autonomy. There has been increasing recognition by the Supreme Court of Canada and legal writers that respect should be given to the human rights and autonomy interests of people with disabilities.
In this section we outline the trajectory from traditional capacity laws in Canada which define an ‘all or nothing’ legally capable/incapable boundary, to more recent legislation and jurisprudence which articulates an expanded range of decision-making statuses through which people can exercise their legal capacity.
While our laws encourage autonomous decision-making, for the most part they create a wall around a group of people whose rights to decide for themselves are removed. This is so because Canadian laws have generally required, as a precondition of engaging in most activities, that an individual possess a requisite level of mental capacity or decision-making ability. When the required level of decision-making ability is absent, the law requires that a substitute decision-maker make decisions in his/her stead.
A. Substitute Decision-making Laws
Legislation in Canada which addresses legal capacity most directly covers guardianship, planning documents such as powers of attorney, consent to health care and admission to care facilities, and adult protection. These laws require that people be [mentally] ‘capable’ to make decisions about their property and personal care, including health care and long-term care residency. Overlaying these are more specific laws: for example, entering into a contract, making a will, acting as a director of a corporation and giving evidence in court each require a person to have a requisite level of mental capacity to do so. There are several additional laws in which legal capacity is addressed but is not the primary subject-matter of the legislation. Rather, provisions are included in laws to cover off situations in which a person’s assessed [mental] incapacity would expose a gap in the legal framework or otherwise affect its functioning. For example, the Canada Pension Plan (CPP) contains a provision allowing for payments to be made to another person or agency when the Minister is satisfied that the CPP recipient is “[mentally] incapable of managing his own affairs”.
Substitute decision-making laws most directly govern situations where people are found [mentally] incapable. These laws are common to all jurisdictions in Canada. For example, Ontario’s Substitute Decisions Act focuses on substitute decision-making, which involves decisions being made by one person on behalf of another, who is usually determined to be [mentally] incapable of making his/her own decisions. It usually takes one of two forms: guardianship, in which an order (usually by a court) is made appointing a substitute decision-maker, and planning documents, in which a person chooses, in advance of [mental] incapacity, who he/she wishes to make decisions on his/her behalf.
Taken together, it is hard to envision any significant area of life that one can engage in freely without potential interference on the basis of so-called [mental] ‘incapacity’. Some of these restrictions may seem reasonable, while others raise questions. But that civil, political and equality rights can be sweepingly restricted in so many fundamental aspects of people’s lives speaks volumes about the status and recognition of people with intellectual, cognitive and psychosocial disabilities in Canadian society.
B. Test of Mental Capacity as a Basis for Legal Capacity: The ‘Understand and Appreciate’ Test
The way in which the law defines mental capacity shapes the nature and extent of its interference with people’s lives, as it is the ascription of mental (in)capacity that determines one’s right to make decisions. It is thus essential to explore the meaning our laws attribute to legal capacity.
There is no single, uniform test or definition for legal capacity in Canadian law. Yet, laws recognize some fundamental realities. The test for legal capacity is described as a cognitive one; hence the focus on mental capacity as a condition for exercising legal capacity. [Mental] capacity is not considered from a global standpoint in that it is recognized that people may have abilities to make some types of decisions on their own and not others. For example, an individual may be able to understand medical information enough to decide to take a medicine for his/her cold, but not be able to understand information to decide whether to have a transplant. Additionally, an individual’s level of decision-making ability may fluctuate over time. Someone who has dementia may have days when he/she is thinking particularly clearly and other days when he/she has a difficult time understanding even basic concepts.
As the test for [mental] capacity or decision-making ability differs depending on the relevant transaction, so too does the required level of [mental] capacity or ability: “[a] person can be [mentally] capable of making a basic decision and not [mentally] capable of making a complex decision.” In Calvert (Litigation Guardian of) v. Calvert, Mr. Justice Benotto concluded that while Mrs. Calvert “…may have lacked the ability to instruct counsel, that did not mean that she could not make the basic personal decision to separate and divorce.” Thus, a person with an intellectual disability may be able to know that she is unhappy where she lives and know that she wants to move to the residence where her friends live and which is near her family. She likely has the decision-making ability to make this decision independently. At the same time, she may not understand information in relation to a decision to purchase a house and may need support and certain accommodations to do so.
Despite the different tests for [mental] capacity, there are similarities between many of them in that they incorporate two basic requirements: the ability to understand relevant information and the ability to appreciate reasonably foreseeable consequences. This test is incorporated in several pieces of legislation in Canada, including Ontario’s Substitute Decisions Act and Health Care Consent Act, Saskatchewan’s Adult Guardianship and Co-decision-making Act and Manitoba’s The Vulnerable Persons Living with a Mental Disability Act. Nonetheless, while this definition is common, it is not the only one that exists in Canada.
Courts emphasize that an assessment of [mental] capacity is based not on the content of the decision ultimately made, but rather on the proce
