As crews battle hundreds of forest fires in B.C., Alberta, and the Northwest Territories, Environment Canada has issued a special air quality statement for many parts of the province, including Calgary.

The statement was issued early Friday morning because smoke from the wildfires has resulted in poor air quality and reduced visibility in many areas.

As a result, people with respiratory conditions such as asthma or existing cardiovascular conditions should monitor their symptoms and consult a doctor if they get any worse.

Residents are also encouraged to reduce or postpone outdoor activities until the air clears.

Alberta Health Services say that minor smoke conditions don’t typically cause health concerns, but if conditions continue to worsen, they could pose some risk.

According to the province, the air quality in Calgary is expected to reach a five out of 10 on the scale, which is a moderate risk for residents.

Health officials recommend that if you taste or smell smoke in the air, you should monitor your symptoms, avoid strenuous activity, and stay inside if necessary.
