Here's a link for an article on the upcoming 406 ELT legislation in Canada.

......, mandating an ELT just using a new frequency .....

isn't everyone else except us here in NA using 406Mhz for aviation? PLB's are 406 now too. Marine locators are 406 as well.
i think the SPOT technology is pretty good... they should definitely have done more to the devices if they are mandating a change. from what i've read and understood, the push is to get off the 121 frequency and move to the more common 406.
I don't think the FAA has anything to do with the phase out and it will be a "cutoff"!.
Here's my letter to Transport:

Dear Sir:
Re: Canada Gazette, Part 1, Vol. 142, No 32, August 9, 2008 ? Regulations Amending the Canadian Aviation Regulations (Parts I and VI ? ELT)
I am a pilot and owner of a small general aviation aircraft, and a professional engineer. I am writing to express my displeasure with the proposed change to the regulations regarding 406 MHz emergency locator transmitters.
I am sure that you have many letters objecting to 406 ELTs. Rather than re-hash the severe economic harm to aircraft owners and the almost complete elimination of private American pilot-tourists flying into Canada, I would like to discuss the bigger picture.
I worked for the (Canadian) company that developed the first commercial 406 beacons, called EPIRBs that are used on many ships and are the basic of personal locator beacons (PLBs) used by hikers. This is the technology base for the 406 ELTs proposed for use in Canadian aircraft.
This technology was developed over 20 years ago, pre-dating the availability of commercial global positioning satellites (GPS) which are now the backbone of navigation systems worldwide.
GPS, combined with other available technologies has rendered 406 MHz ELTs obsolete for their intended purpose.
ELTs, by their nature, must survive an accident in order to be useful. That means they must survive impact, fire, sinking and damage to the antenna or cables as well as the unit itself. The built-in G-switch must trigger and up to one minute must elapse after impact for the ELT to begin transmitting.
One minute is a long time when you are on fire or sinking. Survivors may have time to egress, but then they are alone, with no functioning ELT to help search and rescue find them. Up to 50% of aircraft accidents do not have their ELT survive or trigger.
There are much better systems available today or in the near future that are vastly superior. These devices use GPS positioning to transmit breadcrumb trails to satellites or ground stations. Should an aircraft go missing, or an old-style ELT is triggered it is a simple matter to go to a web site and find a breadcrumb trail for any or all aircraft in an area.
This does not require the survival of any equipment after a crash! Simply being overdue on a flight plan will allow search and rescue to locate a downed aircraft reliably.
Here is an example:

If I had gone missing, It would be obvious where to look. This type of technology has many other uses other than search and rescue, and the relatively modest cost is easy to justify. The total system cost me $100, installed. Commercial systems will cost more, but not thousands of dollars!
It is vastly superior to the obsolete 406 ELT technology that was developed when MS-DOS was popular on every desktop computer.
Please consider this. 406 ELT offer very little for a great cost. There are better alternatives.
Sincerely
Vernon R. Little, P.Eng.
Here's the Minister of Transport's response to all of the objections from the Pilot community. We win (for now).
Canada Backs Off 406 ELTs
Canada's Minister of Transport, John Baird, has overruled his bureaucracy and suspended implementation of a controversial rule that would have required almost all aircraft to have certified 406 Mhz emergency locator transmitters installed by February of 2011 in order to fly legally in Canada.
The rule would have applied to aircraft trying to enter Canada from other countries. In an interview with AVweb at Canadian Aviation Expo in Hamilton, Ontario, earlier this week, Kevin Psutka, president of the Canadian Owners and Pilots Association (COPA), said the minister refused to sign the rule as presented by Transport Canada because it didn't include any viable alternatives to 406 ELTs, even though it included language that indicated an alternative method of compliance was possible. "There is no technology that exists today that could meet those (alternative) requirements," Psutka said. He said the minister has ordered his staff to draft a rule that gives new technology a fighting chance for acceptance.
Psutka and COPA have been fighting the mandatory equipage with 406 ELTs for 10 years, arguing the new ELTs, while somewhat improved in the level and types of information they provide rescuers, suffer from the same operational flaws as the old-style 121.5 units. The vast majority of ELT signals are accidental and do not announce any kind of emergency. On the other hand, when a plane does go down, they fail to trigger more than half the time, according to COPA's research.
Psutka was urging Transport Canada and the Canadian Forces (which handles search and rescue) to consider new GPS-based systems that leave a "bread crumb" trail of position reports for rescuers to follow but the rule, as written, excluded all of them, he said. TC's position was that 406 ELTs meet International Civil Aviation Organization (ICAO) standards that changed when the satellite constellation that monitors search and rescue alerts stopped receiving 121.5 signals. The U.S. did not adopt mandatory 406 equipage, but the military and Civil Air Patrol are recommending aircraft owners install the new ELTs.
