I noticed that between a Canada Air Pilot (Ontario) from 2000 and a copy from this year, non-precision GPS approaches have been popping up like weeds. Part of the reason for that is downloading from the federal government: nearly all airports have been pushed down to the municipalities, and GPS approaches eliminate the cost of maintaining an NDB (giving the airport a slightly better chance of staying open). As far as I know, however, we have only one plane at our flying club with an IFR-certified GPS, while they all have ADF radios. Since our VOR network is much less dense than the American one (often with 100nm or more between stations), we cannot use VOR approaches that often, though there are a couple around Ottawa.
