The latest issue for crossing the border into Canada, is the introduction of eAPIS. See the article on the front page of the COPA web site www.copanational.org entitled " New US Border Crossing Requirement Now Mandatory" with links to more information at www.copanational.org/non-members/ChairmansReport/2009/May/kp09043.htm and www.copanational.org/non-members/body_files/Electronic%20Manifest%20Eng.htm.  

Folks coming from the US must be made aware that they cannot simply call Customs as they did in the past. They must apply to use the system, wait for a reply, set up an account and then learn how to submit reports for both the trip to Canada and return to the US. It's wise to be aware of all requirements, since fines start at $5000 for any mistakes.   eAPIS does not replace contacting Canadian customs as you normally would.

Here's a link to the US customs and border protection site for more information.

In brief,  the current regulation remains in place.
Aircraft can continue to fly with a 121.5 ELT or with a new 406 ELT. Satellite monitoring is limited to 406 MHz, there is no satellite monitoring of 121.5.  Monitoring 121.5 is limited to overflying aircraft and a small number of NAV CANADA facilities.  Members who have not converted to 406 should take extra precautions to maximize their prospects in the event of an emergency.   

The Transport Minister's office has informed COPA that the proposed regulation that would effectively mandate 406 MHz ELTs has not been accepted. Thanks to COPA's representations as well as contacts by COPA members with their Members of Parliament, Minister Baird came to appreciate that the regulation, as drafted, prevents any available alternative from being acceptable.
 
COPA had been pushing for the regulation to be returned to the Canadian Aviation Regulations Advisory Council, in which COPA participates, for further discussion leading to revised wording that would permit alternatives for our sector. The Minister has granted this request. A date for this meeting is being arranged but there is no firm schedule as of the date of this update.

For some background information here's the original notice from Transport Canada re the 406 ELT ( PDF).  When this document  was produced, Transport Canada hoped to have the regulation in place by February 1, 2009.  That has not occurred.
