PLEASE READ: For those wondering, these "prototype" maps are not yet available on ECCC's website. However, they will become operational soon and shared directly on their site. These forecasts and maps are issued by the same Environment Canada Meteorologists that issues all Watches and Warnings for Ontario.
Environment Canada's disclaimer says:
