'Wildfires burning southwest of Sambaa Ke are causing locally poor air quality,' the alert said. 'Air quality and visibility due to wildfire smoke can fluctuate over short distances and can vary considerably from hour to hour.'
Residents may experience mild symptoms such as eye, nose and throat irritations or headaches, the weather agency said. However, if anyone is experiencing fewer common symptoms include wheezing, chest pains or severe cough, they are asked to see medical attention immediately.

Edmonton weather: Cooler and cloudy, but the steadier rain stays south
It's clearing later on Monday and there are seasonal days to follow. A long and broad band of showers and heavy rain stretches from Grande Cache southeast through Red Deer and from Calgary to Medicine Hat this morning. That rain continues to push southeast with the northern edge just grazing the southern part of the Edmonton region and then moving further south of the city as the morning wears on. Rainfall Warnings remain in effect for Calgary and areas to the west and south. For the Edmonton region, we'll stay cloudy through the morning and then get some sunny breaks midday and this afternoon. There's a slight risk of a spotty shower in the area this afternoon, but most of the city should stay dry. Temperatures will top out around 20 C or 21 C this afternoon. Parts of the city may be noticing a smoky smell in the air as a band of wildfire smoke appears to be drifting through the region this morning.

It appears some of that wildfire smoke has bumped air quality readings in the 'moderate risk' range around parts of Edmonton this morning. Air quality should improve this afternoon and Tuesday looks smoke-free. smoke models have some thick wildfire smoke pushing into southern AB today (from the SK fires) and there's a chance that we'll see some of that smoke push into the Edmonton area on Wednesday as the wind shifts to a more southerly direction. Daytime highs will remain in the low 20s through the week. In fact, looking all the way out to the middle of next week, there's really not much chance of 'heat.' There might be one or two days that get to the mid 20s. But, not much chance of seeing any days with afternoons in the 27 to 30 degree range. Here's the forecast for Edmonton and area: Today - Cloudy this morning. Mix of sun & cloud with a slight risk of a shower this afternoon.

Multiple heat and air quality advisories are in place across Canada
Environment Canada has issued heat warnings for several provinces today, including parts of Atlantic Canada, Quebec and Ontario. This is in addition to a number of air quality advisories issued to several parts of the country as a result of wildfire smoke. The heat warnings cover southern Ontario, Greater Montreal and some surrounding areas, central and northeastern Newfoundland, and the Annapolis Valley in Nova Scotia, though the alert is expected to expand to the mainland of the province. In Ontario, expect hot and humid conditions to last through much of this week, with daytime highs between 29 and 32 C. Parts of Quebec, including Greater Montreal, Lachute, Lanaudière, Montérégie and Drummondville, will experience daytime highs of up to 33 C, which combined with high humidity will feel closer to 40. Central and northeastern Newfoundland, including Clarenville and vicinity and the Bonavista Peninsula, will experience temperatures up to 32 C, with a humidex of up to 37, while hot, dry weather will continue in Norman Bay - Lodge Bay, with daytime highs between 27 and 30 C. In Nova Scotia, the heat and humidity is expected to last until Thursday, with daytime highs of up to 33 C, which could feel like up to 37 with humidity. Air quality advisories Air quality advisories have also been issued for eastern parts of Alberta, as well as some regions of the Yukon, Saskatchewan, Manitoba, Quebec and Ontario as a result of wildfire smoke. As winds turn northernly, more of central Saskatchewan will be directly in the path of wildfire smoke. In Ontario, poor air quality and reduced visibility could continue through to Tuesday. Environment Canada warns people in those area of an increased risk to their health. 'People more likely to be affected by wildfire smoke, including people aged 65 and older, pregnant women, infants and young children, people with an existing illness or chronic health condition, and people who work outdoors, should avoid strenuous activities outdoors and seek medical attention if experiencing symptoms,' Environment Canada cautioned.
