Environment Canada weather forecasts are broadcast by their own VHF Weatheradio stations as well as by Canadian Coast Guard Radio services on their VHF Continuous Marine Broadcasts and their Medium Frequency Single Sideband (MF-SSB) broadcasts.
As is the case in the USA, Weatheradio is primarily for land-dwellers. Environment Canada's Weatheradio broadcasts, while of use to boaters who never stray far from home, are of limited value to cruising sailors who need a broader view of the weather situation. The VHF weather transmitters on the island seem to experience frequent "Technical Difficulties", and often transmit erroneous or out-of-date information, esecially in the French version. [For example, in 2016, the French version on the Sydney (Victoria Junction) transmitter gave the Bras d'Or Lakes weather forecast for October 31, 2014 and weather conditions for some unknown date for most, if not all, of the summer season.] Despite advising mariners to monitor the weather for adjacent areas, Environment Canada has cut back on the information transmitted and now only transmits weather forecasts for areas local to the transmitter.
However, CCGR transmits the Technical Synopsis and forecasts for many areas in the vicinity of their transmitters (See MF-SSB broadcasts). The mission of the Canadian Coast Guard is marine safety; their transmissions are usually reliable and of far greater use to cruisers.
