The Weather Network (TWN) is a Canadian English language cable television specialty channel that provides weather information 24 hours a day. Based in Oakville, Ontario, The Weather Network also operates a French language channel called MétéoMédia. The station has a separate feed for the Greater Toronto Area, much like MétéoMédia's separate feed for Metropolitan Montreal, Quebec. An audio-only simulcast of the channel is also broadcast on Sirius Canada channel 138.
