I am happy to be of assistance, unfortunately my DSC expertise is somewhat more limited then my EPIRB's.
There is no policy to exclude small vessels from DSC protocols, but as you suspected, it was more of an oversight. DSC protocols were established about 15 years ago by the International Maritime Organization (IMO) in collaboration with the International Telecommunication Union (ITU). The original intent was to improve the safety of seafarers by forcing vessels to meet minimum emergency alerting standards. These rules apply only to vessels that are both over 360 tons and engaged in international trade. IMO has no regulating authorities and isn't involved in any manners with pleasure crafts. As with most of the IMO rules, industrial countries often extend them to their domestic commercial fleet. The new rules included both DSC and EPIRB, but also other alternative means of alerting that never reached the small crafts community simply because they would be too impractical. Neither IMO and ITU on the international scene, nor Transport Canada and Industry Canada on the domestic scene had planned that DSC would reach the small crafts, let alone in such a short timeframe.
My suggestion would be to seek information from Industry Canada for available or upcoming technology on VHF DSC. They are the approval authority for Canadian communication equipment.
Having been involved in maritime Search And Rescue for 20 years, I am very partial to 406 EPRIBs when it comes to an emergency. However, EPRIBs do not offer that 2 way communication that could help resolve a situation before it gets to that point. The other point that I hadn't insisted on in my previous communication is the requirement to properly register a 406 EPIRB. Suppliers are not all equal, and it is important for the consumer to insist that EPIRB purchased for use in Canada be given a Canadian coding. EPIRB signals will be detected almost anywhere on the globe, but the response from emergency authorities varies significantly based on both location and country of registration. Many low cost EPRIB built in the US can be coded with either US or Canada identification.

Hello Clouatre, Joanne,
Thankyou for that very usefull information.
I understand you probably are not in a position to recommend a particular brand of emergency radio, and I'm not asking you to do that, but I would very much like to obtain your opinion concerning hand-held, DSC/(digital)selective-calling-capable, marine VHF radios.
I am a kayaker who wants to avail himself of a DSC-capable, marine VHF radio. Due to the nature of my vessel, a kayak, it has no built-in electrical system and thus the only option for me is a hand-held rig. Yaesu offers a DSC-capable hand-held, but for it to be connected to a GPS, it has to be in a cradle. The assumption I'm making about this is that there is a deliberate policy of limiting DSC to vessels large enough to have a built-in power supply. Furthermore, when I look in annex "E" and try to find "kayak", or "vessel under oars", there is no MMSI code for such vessels. It's like the designers of the DSC protocol deliberately excluded vessels too small to have built-in power supplies - perhaps they did not foresee hand-held radios/GPS and assumed only larger vessels with electrical systems and fixed-mount radios would ever be in need of DSC.
Uniden makes a hand-held marine VHF rig that is capable of DSC, and has an integrated GPS, but it is vastly overpriced and not very robust, with the main complaint being that the antenna falls off at the slightest impact.
I hope sooner or later, there'll be a handheld, DSC-capable radio that either has integrated GPS or has the ability to connect to a handheld GPS with a small cable, but only if there isn't a deliberate policy of limiting DSC to larger vessels.
My question to you is --- is there a deliberate policy of excluding small vessels like kayaks from the DSC protocol? Also, should I forget about handheld DSC rigs for now and get a 406 epirb? I really can't afford a 406 epirb but if handheld DSC is not a mature technology, or is not intended for kayaks , I suppose I'll have no choice. I would appreciate any comment you may have regarding handheld DSC radios for kayakers.
Regards,
Tom
