The warnings stretch through much of Saskatchewan and most of Manitoba, and into northwestern Ontario as well.

There are also several pockets of affected areas along the Hudson Bay shorelines in northern Ontario, Nunavut, and northern Quebec.

It is also expected to be smoggy in Newfoundland, on the north side of the Avalon Peninsula, with warnings and special air-quality statements in effect.

Environment Canada is advising people to limit their time outdoors and consider postponing outdoor sports and activities.
