Looking further into the boundary data, it appears that on parts of RD
boundaries at sea that don't use the stair step pattern, a line 4.8 km or 3
miles away from the coast is used. Is there an easy tool available to generate
that 4.8 km range?

On the talk-ca list there have been a few discussion about problems
with flooded areas in southern Quebec. The conclusion seems to be
that the problems are due to the rendering of the coastline which only
gets updated every once in a while. The two cases are:
*
The tiles need to be rerendered and over large areas they're not always
detected as having changes so don't need to be rerendered.
I know you can do it manually on a per-tile basis really easily.
Right click on the map where it is map and open image in a new tab. Then
append /dirty to the image
Just to add to this:
in the Montreal area the alignment of the Bing imagery in my
experience is very good. It is nonetheless a good idea to always also
download the GPS tracks and make sure the images match those (and the
Canvec import data).
