Smoke from the Northwest Territories and British Columbia is thick enough in southeastern Saskatchewan Tuesday morning, that Environment Canada's Air Quality Health Index registered a 10 on the 1 to 10+ scale at 4 a.m.

A score of 10 is on the upper end of a high risk. 10+ is a very high risk.

Environment Canada says the at-risk population should "reduce or reschedule strenuous activities outdoors. Children and the elderly should also take it easy."

The agency says the at-risk population includes:

  • seniors
  • pregnant people
  • infants and young children
  • people who work outdoors
  • people involved in strenuous outdoor exercise
  • people with an existing illness or chronic health conditions, such as:
    • cancer
    • diabetes
    • mental illness
    • lung or heart conditions

Environment Canada Meteorologist Terri Lang said on Monday that the smoke could lessen on Wednesday when the wind shifts to the southeast.
