The Heart and Stroke Foundation of Canada recommends that you get your blood pressure checked at least once every year by a healthcare provider.

If you have been diagnosed with high blood pressure (or other related conditions), your doctor may recommend that you get it checked more often. Be sure to ask your doctor how often you should have your blood pressure checked.

Measuring your blood pressure regularly, as instructed by your doctor, is an important part of controlling it.
