Canada and the US have been partners in border security for some time. There used to be a specific organization that coordinated such activities at regional levels called Integrated Border Enforcement Teams that focused on the coordination on both sides of the border (including both federal, state, provincial and local agencies police services on the border as well as both federal border agencies).
I note that the term IBET seems to be missing from the RCMP websites in the last year or so although there is still a site that talks about the same issues called "Border Security. (Note, however, that the web page address is still "ibet-eipf"
http://www.rcmp-grc.gc.ca/ibet-eipf/index-eng.htm). They certainly still carry out all the same functions including the joint "Ship Rider Program" on the Great Lakes and other maritime areas and I wouldn't doubt that IBETs still exist in the RCMP but the term just isn't "out there" as it was in the past.
