Blood Pressure Guidelines in Canada: Hypertension Canada Explained

Canada's national guidance comes from Hypertension Canada, whose 2025 guideline for primary care was published in the Canadian Medical Association Journal (CMAJ). It defines hypertension as a blood pressure of 130/80 mmHg or higher, measured with a validated device under proper conditions — and it deliberately uses that one threshold in every setting.

This is a real change, and older numbers are still everywhere. Before 2025, Canada used two thresholds: 140/90 mmHg in the office and 135/85 mmHg for home and automated measurements. The 2025 guideline retires that split — one number, 130/80, now applies whether the reading was taken in a clinic, at home, or by an ambulatory monitor. If a Canadian chart you find online says hypertension starts at 140/90, it predates the current guideline.

The guideline also strongly recommends confirming a diagnosis with out-of-office measurement — home monitoring or 24-hour ambulatory monitoring — which catches both white coat hypertension (high only at the clinic) and masked hypertension (high only outside it).

Diagnosis and treatment use different numbers, and the 2025 guideline is unusually clear about both:

• The treatment target is a systolic pressure below 130 mmHg, provided treatment is well tolerated. There is no diastolic target — the guideline sets only the top number, individualized for people who are frail, prone to falls, or affected by dizziness on standing.
• Medication is recommended for everyone with a blood pressure of 140/90 mmHg or higher.
• Between 130–139 mmHg systolic, medication is recommended only when cardiovascular risk is high. For everyone else in that band, the prescription is healthy lifestyle changes, with blood pressure and risk reassessed in 3–6 months.
• Lifestyle changes are recommended for all adults with hypertension, whether or not medication is started.

In other words: being diagnosed at 132/84 does not automatically mean pills. It means the conversation starts — and a week of proper home readings is the most useful thing you can bring to it.

Hypertension Canada's home-monitoring standard is duplicate readings, morning and evening, for 7 days — two readings each sitting, which comes to 28 readings in a week. Its own home log sheet spells out the conditions that make those readings count:

• Use a validated automated device (see the next section)
• Always measure after resting five minutes, without talking
• Measure before taking your blood pressure medication
• At least 2 hours after a meal, and after emptying your bladder
• 1 hour after coffee or smoking, and 30 minutes after exercise
• Sit with your back supported and legs uncrossed, feet flat on the floor
• Keep your arm bare and supported, with the cuff at heart level

Our step-by-step measurement guide walks through the same setup with photos, and our blood pressure log template covers what to record at each sitting.

If you prefer paper, Hypertension Canada publishes a fillable 7-day Home Blood Pressure Log laid out exactly for this routine (a French version, the Journal personnel de la pression artérielle, exists too). Use it as a recording sheet: the small category table printed on it predates the 2025 guideline, so read your results against the 130/80 threshold above, not the sheet's older staging. The log also carries one habit worth adopting — bring your monitor to your healthcare professional once a year to have its accuracy checked.

Hypertension Canada runs a device-recommendation program, and its list of recommended monitors is the Canadian answer to "which one should I buy?" — every device on it has been validated to the current international accuracy standards (AAMI/ISO/ESH 2018). The list is searchable and can be filtered by brand, device type (home, clinic-grade, ambulatory), connectivity, and cuff size.

Validated models may carry the “Recommended by Hypertension Canada” logo on their packaging, so you can spot them on a pharmacy shelf. Heart & Stroke gives its patients the same advice: pick a device recommended by Hypertension Canada.

For what actually separates the categories — upper-arm cuffs, wrist monitors, and the cuffless watches and rings that are not on any validation list — see our guide to the types of blood pressure monitors.

As of 2025, Canada and the United States define hypertension from the same number: 130/80 mmHg. The US ACC/AHA guideline set that threshold in 2017 and kept it in its 2025 update; Canada's 2025 guideline adopted it, explicitly noting consistency with other international guidelines. European guidelines still diagnose hypertension from 140/90 mmHg, so a chart from a European source will draw the line higher than your Canadian doctor does.

For app users this alignment is convenient: the Blood Pressure Journal app ships with the ACC/AHA bands as its default — below 120/80 normal, hypertension from 130/80 — so a Canadian user's default classification boundary already matches the national guideline. The app's classification ranges are also customizable, so if your doctor works to individualized targets, you can set the bands to match. Either way, the number that matters most is your average: a home average at or above 130/80 mmHg over a proper 7-day series is the figure to bring to your doctor.

The stakes are worth stating plainly. Heart & Stroke calls high blood pressure the number one risk factor for stroke and a major risk factor for heart disease, and nearly 8 million Canadians have been diagnosed with it — most of them feeling perfectly fine, which is why it's called the silent killer.

A single high reading is usually not an emergency. If your monitor shows something startling, sit quietly for a few minutes and measure again — stress, a rushed setup, or a too-small cuff can all inflate a reading.

But if your blood pressure is above 180/120 mmHg and you have symptoms — chest pain, shortness of breath, weakness or numbness, trouble speaking, or vision changes — treat it as an emergency and call 9-1-1 (in Canada) or go to the nearest emergency department.

If a reading is very high but you feel well, or you're simply unsure what to do next, you can call 8-1-1, the free health-advice line available in most provinces and territories — in Québec, for example, it reaches the Info-Santé 811 nursing service, 24 hours a day. A nurse can help you decide whether it can wait for your family doctor or needs attention now.
