Blood sugar levels can help show how your body uses glucose, which is a main source of energy. In Canada, blood sugar is usually measured in millimoles per litre, written as mmol/L. A single reading does not always tell the full story, but patterns in fasting glucose, after-meal glucose, and A1C can help your healthcare provider assess your risk for diabetes, prediabetes, or blood sugar concerns.
For adults in Northeast Calgary, North East Medical Clinic provides family practice and primary care, walk-in medical care, and diabetes and weight management support based on clinical assessment and availability.
What Is a Normal Blood Sugar Level in Canada?
A “normal” blood sugar level depends on the type of test, when you last ate, your health history, and whether you have diabetes.
For diagnosis, Alberta patient guidance based on Diabetes Canada criteria states that diabetes may be diagnosed when fasting blood sugar is 7.0 mmol/L or higher, A1C is 6.5% or higher, or a 2-hour oral glucose tolerance test is 11.1 mmol/L or higher. Prediabetes may be considered when fasting blood sugar is 6.1 to 6.9 mmol/L, A1C is 6.0% to 6.4%, or a 2-hour oral glucose tolerance test is 7.8 to 11.0 mmol/L. These results should be interpreted by a healthcare provider, and diagnosis often requires confirmation. (myhealth.alberta.ca)
Blood Sugar Levels Chart for Canadian Adults
| Test or Timing | General Range to Know | What It May Mean |
|---|---|---|
Fasting blood sugar below 6.1 mmol/L | Often considered below the prediabetes range | Your provider may still consider symptoms and risk factors |
Fasting blood sugar 6.1 to 6.9 mmol/L | Prediabetes range | Follow-up testing and prevention planning may be recommended |
Fasting blood sugar 7.0 mmol/L or higher | Diabetes range | A repeat or confirmatory test may be needed |
A1C 6.0% to 6.4% | Prediabetes range | Reflects average blood sugar over about 2 to 3 months |
A1C 6.5% or higher | Diabetes range | Should be reviewed with a healthcare provider |
2-hour OGTT 7.8 to 11.0 mmol/L | Prediabetes range | Shows how your body responds to glucose |
2-hour OGTT 11.1 mmol/L or higher | Diabetes range | Requires medical interpretation |
Blood Sugar Targets for Adults With Diabetes
For most non-pregnant adults with type 1 or type 2 diabetes, Alberta patient guidance notes that many experts suggest an A1C of 7.0% or less, a before-meal blood glucose range of 4.0 to 7.0 mmol/L, and a 2-hour after-meal range of 5.0 to 10.0 mmol/L. (myhealth.alberta.ca)
These are general targets. Your personal target may be different if you are older, pregnant, taking medications that can cause low blood sugar, have other health conditions, or have a history of hypoglycemia. Diabetes care guidelines emphasize that blood sugar targets should be individualized based on age, diabetes duration, cardiovascular risk, hypoglycemia risk, and life expectancy. (www2.gov.bc.ca)
What Is A1C?
A1C is a blood test that estimates your average blood sugar over the past 2 to 3 months. It is often used for diabetes screening, diagnosis, and monitoring.
A1C is useful because it is not based on a single moment in the day. However, it may not be appropriate for everyone. Pregnancy, recent blood loss, blood transfusion, some blood disorders, and certain medical treatments can affect results, so your provider may recommend another test when needed.

When Should You Check Your Blood Sugar?
Your healthcare provider may recommend blood sugar testing if you have risk factors such as:
- Family history of type 2 diabetes
- Higher body weight or weight-related health concerns
- High blood pressure or high cholesterol
- History of gestational diabetes
- Symptoms such as increased thirst, frequent urination, fatigue, blurry vision, or unexplained weight changes
- Previous results in the prediabetes range
Canadian guidance also supports screening adults age 40 and older, or younger adults with risk factors, to avoid missing undiagnosed blood sugar concerns. (www2.gov.bc.ca)
What Can Affect Blood Sugar Levels?
Blood sugar can change throughout the day. Common factors include:
- Meals and carbohydrate intake
- Physical activity
- Sleep quality
- Stress
- Illness or infection
- Alcohol intake
- Medications
- Hormonal changes
- Timing of diabetes medication or insulin, if prescribed
Because blood sugar is affected by many factors, it is better to look at trends with a healthcare provider instead of relying on one reading alone.
What If Your Blood Sugar Is High?
If your blood sugar is higher than expected, do not assume the cause or change medication on your own. Book a medical assessment, especially if readings stay elevated or you have symptoms.
At North East Medical Clinic, patients in NE Calgary can access diabetes and weight management care, which may include screening, A1C and fasting glucose review, ongoing monitoring, medication management, and referrals when clinically appropriate.

Frequently Asked Questions
What is a normal fasting blood sugar level in Canada?
A fasting blood sugar below 6.1 mmol/L is generally below the Canadian prediabetes range. A fasting result of 6.1 to 6.9 mmol/L may suggest prediabetes, while 7.0 mmol/L or higher may be in the diabetes range and should be reviewed by a healthcare provider.
What is a good A1C for adults?
For many non-pregnant adults with diabetes, an A1C target of 7.0% or less is commonly used, but personal targets vary. A healthcare provider may recommend a different target based on age, medications, low blood sugar risk, pregnancy, or other medical conditions.
Is 7.0 mmol/L high for blood sugar?
It depends on timing. A fasting blood sugar of 7.0 mmol/L or higher is in the diabetes diagnostic range. After eating, blood sugar is expected to rise, so the meaning of 7.0 mmol/L depends on when you tested and your health history.
Can prediabetes be improved?
Prediabetes can often be managed with early lifestyle and medical support. Healthy eating, regular physical activity, weight management where appropriate, and follow-up testing may help reduce the risk of developing type 2 diabetes, but individual results vary.
Where can I get blood sugar checked in NE Calgary?
