A large swath of Ontario is struggling to stay above water as heavy Friday rainfall exacerbates flood concerns in multiple regions. Heavy rain started in Toronto and much of southern Ontario in the morning and stretched through the afternoon. Some areas could see the rain change to flurries overnight. While Torontonians merely needed to pack an umbrella, residents about 150 kilometres north, in the towns of Bracebridge and Huntsville, are grappling with a more dangerous situation.
