The Industry Canada plan for the transition to Digital Television in Canada has been released. You can download the plan at http://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/DTV_PLAN_Dec08-e.pdf/$file/DTV_PLAN_Dec08-e.pdf
Nothing major crazy in the plan, but some stations are moving which will affect the type of antenna you have. If you are looking for an antenna, check out the antenna chart at Digital Home. It is a really good guide for selecting the proper antenna for your needs. Its is based on real life experience, not theory.
I had a Channel Master 4221 clone for a while here at my apartment for my flat screen LCD and I was very happy with the results for UHF and even VHF-Hi, which it is not supposed to be good. The antenna is now at my girlfriend’s parents place working as a their main antenna and they have been happy with the results for their analog reception. Once Tracey and I get a house, my plan is to get a Channel Master 4228 as well as a good VHF only antenna and a FM antenna for the stereo.
