There was never anything officially announced (are these things ever officially announced?), but the May 27, 2006 show ended with a roll call of all the past contributors to Brave New Waves and what sounded like a final goodbye. (A low quality recording of the May 27 show in Ogg Vorbis format has been uploaded here: http://www.megaupload.com/?d=360EO9F0; Michael Barclay has posted the set list here.)
Then, in September 2006, after months of repeats, new shows began airing featuring new hosts. The format changed to one hour of new music followed by three hours of material culled from the archives ("the best of Brave New Waves, with Patti Schmidt"). The new hosts included Jarrett Martineau (previously host of CBC TV's Zed Real), Steve Guimond (CKUT-FM, Hour magazine), Helen Spitzer, and Joshua Karpati.
On Wednesday January 17, 2007, the CBC announced major changes to its radio programming.
As of March 19, 2007, Brave New Waves will no longer be broadcast on
CBC Radio Two.

The first article above seems to imply that the show will become available on one of CBC's Sirius satellite radio channels. It is unclear whether there will be new shows or just repeats from the archives.
Update (22/01/2007): The first article was updated since I last read it and there is now no reference to Brave New Waves. It used to read:
With Radio Two poised as an adult-oriented music service, the public broadcaster's more youth-oriented music offerings - like CBC Radio Three and Brave New Waves - will only be available on CBC's Sirius satellite channels and via podcasting.but now there is no mention of Brave New Waves.

This is the final broadcast of Brave New Waves. My name is Patti Schmidt, and it has been my great joy and privilege to have worked on this program for 16 of its 23 years. My deepest thanks to everyone who stumbled in, and stayed, either by accident or design. When the new Radio 2 schedule launches next week, I'll be hosting the weekend edition of Canada Live, a concert show seven nights a week, 8 to 10pm, highlighting what's on stage across the whole country, from classical to contemporary. I hope you can tune in.
