Capacity Is Not All or Nothing: Planning Before It Is Too Late

Many people assume capacity is a single switch that is either on or off. The law is more subtle, and that subtlety is why planning early matters.

Capacity is decision-specific

Under Ontario's Substitute Decisions Act, capacity is assessed in relation to a particular decision and a particular time. A person may have capacity for some decisions and not others. Broadly, it turns on whether the person can understand the relevant information and appreciate the reasonably foreseeable consequences of a decision.

Why the timing is everything

You can only grant a power of attorney while you still have capacity to do so. Once capacity is lost without a valid POA in place, your family may have to apply for guardianship, a slower, more expensive and more intrusive process overseen by the court and the Public Guardian and Trustee.

The cruelty of incapacity is that it often arrives gradually, and the window to plan closes quietly. By the time the need is obvious, the legal tools may be out of reach. Planning while clearly well is the only reliable protection.

A plan that fits your life

Sound incapacity planning, the right powers of attorney, clear wishes, and coordination with your will, lets the people you trust step in smoothly, instead of fighting the system in a crisis.

行为能力并非“全有或全无”:趁来得及先规划

很多人以为“行为能力”是一个非开即关的开关。法律其实更精细,而正是这种精细,决定了为何要尽早规划。

2026年10月24日发布 · 2026年10月24日对照安省遗产法核实 · 作者:禹晟遗嘱与遗产团队

能力是“就事论事”的

根据安省《替代决策法(Substitute Decisions Act)》,行为能力是针对某一具体决定、某一具体时点来评估的。一个人可能对某些决定有能力、对另一些没有。大体上,取决于此人能否理解相关信息、并领会一项决定可合理预见的后果。

为什么时机就是一切

你只能在仍具备相应能力时授予授权书。一旦在没有有效授权书的情况下丧失能力,你的家人可能不得不申请“监护(guardianship)”,那是一个更慢、更贵、也更具侵入性的程序,由法院与“公共监护与受托人办公室(PGT)”监督。

丧失能力的残酷之处在于,它往往是渐进到来的,而规划的窗口会悄悄关上。等到需要已经显而易见时,法律工具可能已触不可及。在明显健康时规划,是唯一可靠的保护。

一套契合你生活的计划

稳妥的“丧失能力规划”,恰当的授权书、清晰的意愿、与遗嘱的协调,能让你信任的人顺畅地接手,而不是在危机中与制度角力。
