[Talk-ca] Buildings in Montreal

So we have the centre mapped for buildings.

We could invite people to add tags to the existing building outlines.

Doing it the hard way we could set up a task to map building outlines in a
small section of Montreal and use conventional JOSM mappers to draw in the
outlines.

I suggest using a small section to keep the new buildings together just in
case someone comes up with a magic spell to import the buildings.  Once the
small section is done then set up the next.

Suggestions from local mappers as to which area(s) they would like doing
first if they would like to proceed is this way.

Thanks

John
