Wildfire smoke is continuing to impact air quality in Hamilton, Brantford and the Niagara Region. 

Environment Canada issues a special air quality weather statement on Sunday afternoon that also includes the Haldimand, Norfolk and Brant counties. 

Hazy skies may continue into Monday, said the federal weather agency.

It issued a similar advisory ealier in the week with the smoke originating from wildfires in the Prairies. 

"Air quality and visibility due to wildfire smoke can fluctuate over short distances and can vary considerably from hour to hour," said the statement Sunday. 

Smoke can cause eye, ear, nose and throat irritation, headaches or a mild cough, Environment Canada said. It can also cause chest pains and wheezing.

The agency says seniors, pregnant people, kids and babies, people with health conditions and those who work outdoors should reduce activity outdoors and seek medical help if experiencing symptoms.

It adds that when indoors, people should keep their windows closed as much as possible, but that during extreme heat, it's best to prioritize keeping cool.
