Hi all,
Last weekend was held a Canvec Import mapping party in Sherbrooke. One of the participant asked if there were significant differences between NAD83 (Canvec and GeoBase datum) and WGS84 (Osm datum) e.g.: are converted Canvec file would fit the Osm data?
As nobody known if there was a correction of some type within the java conversion application, I have checked to make sure we were not in trouble.
Here is the answer:
Even if there is no datum correction done when converting Canvec to Osm, the largest difference between both datum in Canada is 1.5 meter.

So, go ahead, the result is ok!
