British Columbia in Canada has a representation agreement act. Representation agreements allow people with disabilities to nominate someone to make decision on their behalf. The person with disabilities makes their decisions with the help of this person. This system is better than the alternative which is legal guardianship which takes away the person with disabilities' rights

Canada is at the forefront of independent living. They have ratified the UN Convention on the Rights of Persons with Disabilities (UNCRPD) and the district of British Columbia has pioneered representation agreements.

Representation Agreements allow a trusted person to act as a person with disabilities’ representative. Rather than legal guardianship, which strips a disabled person’s voice and restricts their rights, representation agreements allow others to speak on their behalf.

British Columbia’s Representation Agreement Act was part of the inspiration for Article 12 of the United Nations Convention on the Rights of People with Disabilities (UNCRPD)

This article of the UNCRPD calls on governments to implement legislation that ensures all adults receive support with decision making without taking away or restricting rights.
