New evacuation alert issued for Wesley Ridge wildfire on Vancouver Island
Social Sharing The Regional District of Nanaimo has issued a new evacuation alert for properties near the Wesley Ridge wildfire on Vancouver Island. The latest alert, which adds to an existing one and means residents are expected to be ready to leave at a moment's notice, affects addresses on three roads in the area. The Wesley Ridge fire was discovered Thursday, according to the B.C. Wildfire Service (BCWS), and is burning on the north banks of Cameron Lake, about 50 kilometres northwest of Nanaimo, B.C. The regional district said it would update the public with the new number of affected properties in a news conference before noon on Tuesday. On Monday, the district said 387 properties were affected by an evacuation order, which requires residents to leave immediately. Another 235 properties, not including the new alert issued late Monday, were affected by an evacuation alert. According to the last update from the wildfire service on Monday morning, the Wesley Ridge fire remained at 511 hectares in size. Rory Colwell, fire behaviour analyst with BCWS, said in a communications video Monday that the area shows evidence of drought. He said the "build up index" of fuels that are available to burn is about 150 per cent of what would be normal at this time of year. "You can see how dry and crunchy the ground is," Colwell said. "Some of the logs … are showing as low as 10 or 12 per cent moisture content — and kiln-dry lumber is about eight per cent." "We're getting full consumption of this, and it's causing the fuels and the fire to spread in areas and in ways that we wouldn't normally see." At a news conference Monday, fire information officer Madison Dahl stressed the need for rain. "We are not having soaring temperatures, and we are expecting a little bit of precipitation, but we are still seeing very dry conditions here on the coast and on Vancouver Island," she said. "It is going to take a lot of rain to be able to substantially lower the fire behaviour that we are seeing." Dahl also said BCWS aircraft need space to safely and quickly collect water to fight the fire, and asked boaters to respect that. "If there are aircraft nearby, move to the shore. Stay out of their way," she said. The Wesley Ridge fire is suspected to be human-caused, a categorization given to any wildfire not sparked by lightning.

CP24's Andrew Brennan reports from the Toronto lakefront where haze from wildfire smoke blankets the downtown skyline. Special air quality statement in effect for Toronto and the GTA Toronto will once again see diminished air quality on Tuesday as smoke from forest fires in other regions drift into the city. A special air quality statement has now ended but Toronto's air quality was among some of the worst in the world on Tuesday morning. According to Swiss air quality tracker IQAir, Toronto's air quality was ranked 6th worst in the world early Tuesday morning. wildfire map Aug. 5, 2025 The map from Environment and Climate Change Canada shows the dispersion of wildfire smoke fine particulate matter for the next 72 hours from August 5, 2025. (Environment and Climate Change Canada) Toronto will also see a return of humid weather on Tuesday, with a daytime high of 29 C, feeling closer to 34 with the humidity. The national weather agency previously said GTA residents may experience some unpleasant symptoms as a result of the smoke, including eye, nose, and throat irritation, as well as headaches or a mild cough. Environment Canada said more serious symptoms, which are less common, include wheezing, chest pains or severe cough. Those who are more likely to be impacted by poor air quality include older individuals, pregnant people, young children, people with chronic health conditions, and those who work outdoors. CP24 Meteorologist Bill Coulter said hot and 'mostly dry' weather is in the forecast for the start of the work week. 'Smoke from forest fires has been reducing air quality over the last few days,' he said. 'That air quality is gradually improving and will continue to improve as winds sift to tap into hot and humid air from the (United States) and cuts off the flow of smoky air from northern areas.'
