software before. I question exactly where it gets its "Canadian"
data source. Some information like airspace and nav-aids are
available freely in the DAH (PDF online). The only reason why I
have a concern is I'm in talks right now with NavCanada on
getting aviation data for my website. They have a limited
selection of data available for commercial purposes.  I think if
anything, this company aggregates all free information and
channels them through a subscription service.
