The age of majority in Canada varies by province: it is 18 in Alberta, Manitoba, Ontario, Prince Edward Island, Quebec, and Saskatchewan, and 19 in British Columbia, New Brunswick, Newfoundland and Labrador, Nova Scotia, the Northwest Territories, Nunavut, and Yukon.1Ontario.ca. Age of Majority and Accountability Act, RSO 1990, c A.72BC Laws. Age of Majority Act, RSBC 1996, c 7 That birthday is the day you stop being a minor under provincial law and become a full adult, with the right to sign binding contracts, sue in your own name, make your own medical and financial decisions, and marry without parental consent.
Quick Lookup by Province and Territory
Age of majority is 18 in:
- Alberta
- Manitoba
- Ontario
- Prince Edward Island
- Quebec
- Saskatchewan
Age of majority is 19 in:
- British Columbia
- New Brunswick
- Newfoundland and Labrador

Each province and territory sets this threshold in its own statute. Ontario’s Age of Majority and Accountability Act, for example, states that a person “attains the age of majority and ceases to be a minor on attaining the age of eighteen years.”1Ontario.ca. Age of Majority and Accountability Act, RSO 1990, c A.7 British Columbia’s Age of Majority Act does the same thing at 19.2BC Laws. Age of Majority Act, RSBC 1996, c 7 Someone who turns 18 in Ottawa is a legal adult; someone the same age in Fredericton or Halifax is still a minor for another year.
What Changes on Your 18th or 19th Birthday
Reaching the age of majority removes what the law calls the disability of minority. From that day, you can do the following without a parent, guardian, or court involved:
- Sign contracts that are fully enforceable against you. Leases, car loans, and cellphone agreements are binding. Before majority, most contracts a minor enters into can be voided by the minor.
- Sue or be sued in your own name. Minors need a litigation guardian to appear in court; adults do not.
- Own and manage property, hold title to real estate, manage investments, and write a legally valid will.
- Marry without parental or guardian consent. The minimum age for marriage in Canada is 16, but anyone below the age of majority needs consent from a parent or guardian. That requirement disappears at 18 or 19.3Statistics Canada. Canadian Vital Statistics – Marriage Database: Definitions
- Make your own medical decisions and control who sees your health records.
The autonomy comes with full accountability. Parents and guardians are no longer legally required to support you, and you bear the consequences of the contracts and decisions you make.
Medical Consent Is Slightly Different
Most provinces don’t set a separate statutory age for medical consent, so before the age of majority a healthcare provider assesses a young person’s capacity case by case. Two provinces are explicit: Quebec allows minors aged 14 and older to consent to care required by their health, and New Brunswick’s Medical Consent of Minors Act lets 16-year-olds consent as if they had reached majority. Once you actually reach the age of majority, you have full authority to accept or refuse treatment anywhere in Canada, and a parent no longer has a right to your records.
Drinking, Cannabis, and Gambling Follow Separate Rules
Becoming a legal adult does not automatically unlock every age-restricted activity. These ages are set by separate provincial statutes, and they don’t always line up with the age of majority.
Alcohol
The legal drinking age is 18 in Alberta, Manitoba, and Quebec, and 19 in every other province and territory. That means if you live in Ontario, Saskatchewan, or Prince Edward Island, you are a legal adult at 18 but cannot buy alcohol until 19.
Cannabis
The federal Cannabis Act sets a national floor of 18, so no province can allow sales below that age.4Health Canada. The Cannabis Act: The Facts Provinces can go higher, and most that have a 19 drinking age also require you to be 19 to buy cannabis. In practice, the cannabis age tracks the drinking age within each province.
Gambling
Gambling is allowed at 18 in Alberta, Manitoba, and Quebec, and at 19 in every other province and territory. Again, Ontario, Saskatchewan, and Prince Edward Island are the provinces where you’re an adult at 18 but can’t legally gamble until 19.
Federal Ages That Ignore the Provincial Split
Federal law sets its own thresholds that apply the same way across the country, no matter what your province considers the age of majority.
Voting
Every Canadian citizen aged 18 or older can vote in federal elections. The right comes from section 3 of the Canadian Charter of Rights and Freedoms and is carried out through the Canada Elections Act.5Elections Canada. The Evolution of the Federal Franchise An 18-year-old in British Columbia can vote federally even though provincial law still treats them as a minor.
Criminal Law
The Youth Criminal Justice Act defines a young person as someone aged 12 to 17. On your 18th birthday, no matter which province you live in, you are prosecuted in adult court under adult sentencing rules.6Justice Laws Website. Youth Criminal Justice Act
Military Service
The Canadian Armed Forces accept applicants as young as 16 for officer training at a Royal Military College and 17 for most other regular and reserve force positions. Anyone under 18 needs written consent from a custodial parent or legal guardian.7Government of Canada. DAOD 5002-1, Enrolment The provincial age of majority is not part of the calculation.
Tobacco and Vaping
Federal law makes it illegal to sell tobacco or vaping products to anyone under 18 nationwide.8Health Canada. Preventing Kids and Teens From Smoking and Vaping Some provinces raise the age to 19 or add display bans, but 18 is the federal floor.
Can a Minor Be Declared an Adult Early?
In most Canadian provinces, no. Unlike the United States, provinces such as Ontario and British Columbia have no formal court process to emancipate a minor. A young person living independently may gain practical autonomy in some areas, but their legal status doesn’t change until they reach 18 or 19.
Quebec is the exception. Its Civil Code recognizes two forms of emancipation. Simple emancipation expands a minor’s rights, such as managing day-to-day finances, while keeping some protections in place, and can happen through a declaration filed with the Public Curator or by court order. Full emancipation grants nearly all the rights of an adult and requires either marriage or a court ruling. Even full emancipation leaves a few restrictions in place, so it is not a complete substitute for reaching the age of majority.
Outside Quebec, courts may recognize a minor’s independent status in narrow contexts, like enforcing a contract for necessities, but there is no general declaration of adulthood. For nearly everyone else in Canada, the only reliable path to full legal adulthood is the 18th or 19th birthday set by your province or territory.
