Canada's Low-Risk Alcohol Drinking Guidelines
Canada's Low-Risk Alcohol Drinking Guidelines provide adults, ages 25 to 65 who choose to drink, information on alcohol and related health risks so that they can make an informed choice about drinking.
By choosing to limit their alcohol consumption, adults can reduce their risk of short and long-term alcohol-related harms, such as injuries and certain chronic diseases.
For more information and related reports, see Canada's Low-Risk Alcohol Drinking Guidelines.
Guideline 1: Reduce long-term alcohol-related health risks
Drink no more than:
- 10 drinks a week for women, with 2 or less drinks a day on most days
- 15 drinks a week for men, with 3 or less drinks a day on most days
Guideline 2: Minimize risk of injury and harm
Drink no more than:
- 3 drinks (for women) at any one time
- 4 drinks (for men) at any one time
In Ontario, the maximum Blood Alcohol Concentration (BAC) for licensed drivers is 80 mg of alcohol in 100 ml of blood. Driving with a BAC in excess of 0.08 is a criminal offense. New drivers with a class G1 license must have a BAC of zero. Use your weight and the number of drinks per hour to estimate your Blood Alcohol Concentration (BAC).
The safest choice is to plan ahead. Don't drink and drive.
Guideline 3: When to avoid drinking
Do not drink when:
- Driving a vehicle or operating machinery and tools
- Taking prescription or over-the-counter medicines or drugs that interact with alcohol
- Doing any kind of dangerous physical activity
- Living with mental or physical health problems
- Pregnant or planning to be pregnant or about to breastfeed
- Responsible for the safety of others and making important decisions
- Living with alcohol dependence
Guideline 4: Pregnancy and breastfeeding
It is safest not to drink:
- If you are pregnant or planning to become pregnant
- Before breastfeeding
Any kind of alcohol can be harmful during pregnancy including liquor, beer, wine and coolers. Learn about Fetal Alcohol Spectrum Disorder.
Guideline 5: Delay your drinking
Youth should delay their drinking until their late teens, as alcohol is harmful to the development of the brain and body. Teens should plan ahead and follow local drinking laws.
If teens choose to drink, they should:
- Drink under parental guidance
- Never drink more than 1-2 drinks at a time, and never more than 1-2 times per week
Youth in their late teens to age 24 years should never exceed the daily and weekly limits outlined in Guideline 1.
It's important for parents to talk to their teens about alcohol.Adapted with permission from Canadian Centre on Substance Abuse, Canada's Low-Risk Alcohol Drinking Guidelines, 2011.
