Well, one of the rather laborious part of an import is to merge the
imported data with what has already been there before. This is a manual
process anyway as it requires some human judgement (keep, delete, merge,
or whatever).

If you want to have a look at the CanVec data, the file you need to
download is this one: http://ftp2.cits.rncan.gc.ca/osm/pub/062/L/062L15.zip

Within the archive the files 062L15.1.2.osm and 062L15.1.3.osm seem to
cover Melville itself. So I would start by one of those and load it into
JOSM. I just had a look myself and I think that's a pretty good starting
point which should be faster than tracing.

What you would have to do then is probably to check the tagging with
your local knowledge, remove anything not useful/inaccurate/whatever and 
do the merging.
