None of the currently operating stations are Canadian... and the conflicting ones, which are, don't exist yet.

No, there's absolutely no mandated deadline in Canada to drop analog. It's being run as a "market driven" transition. Actual broadcast HDTV is only available from a few stations in a few cities at any rate. Most other Canadians get their HDTV from cable or satellite, where all the national networks (plus a few minor ones) are already providing HDTV content.
