The alerts cover a broad swath of communities, including Newmarket, Georgina, and northern York Region; Vaughan, Richmond Hill, and Markham; Barrie, Collingwood, and Hillsdale; Owen Sound, Blue Mountains, and northern Grey County; Listowel, Milverton, and northern Perth County; Stratford, Mitchell, and southern Perth County; Waterloo and Wellington; Innisfil, New Tecumseth, and Angus; Halton Hills and Milton; Burlington and Oakville; Niagara; and the City of Hamilton. Additional warnings extend to Midland, Coldwater, and Orr Lake; Orillia, Lagoon City, and Washago; as well as Bracebridge and Gravenhurst. Officials classify the impact as moderate with high forecast confidence, highlighting the potential for wind chills ranging from minus 30 to minus 35 degrees Celsius in most areas, and up to minus 33 to minus 38 in the eastern extensions near Georgian Bay.
