Greetings,
I am proposing to import the City of Montreal's contiguous building outline
dataset, parsed into individual building outlines and with out-of-date
buildings removed using the City’s Property Assessment Roll dataset. Both
datasets are sourced from the City of Montreal’s open data portal.
## Documentation
This is the wiki page for my import:
https://wiki.openstreetmap.org/wiki/Montr%C3%A9al/Imports/B%C3%A2timents
This is the source dataset's website:
https://donnees.montreal.ca/dataset/batiment-2d
The above source, containing the contiguous building outlines, has been parsed
into individual buildings and has had stale data removed with the help of the
following data:
https://donnees.montreal.ca/dataset/unites-evaluation-fonciere
This is a file I have prepared which shows the data after it was translated to
OSM schema (conflated with OSM data as of January 21, 2023):

I have checked that this data is compatible with the ODbL.

## Abstract
The dataset contains contiguous building outlines from the City of Montreal,
parsed into individual building outlines and with out-of-date buildings
removed. Buildings that intersect with existing OSM buildings were also
removed. This equates to just under 137 000 individual buildings. All buildings
were simply tagged as building=yes and also include a tag for the source linked
above. Conflation, i.e. removing buildings from the import which would
intersect with existing OSM buildings, will be repeated once more on the day of
the import in QGIS. Using JOSM, the data will then be converted to an OSM XML
and uploaded in chunks of 9000.
## Next Steps
Please let me know of any issues. If there aren't any, once the delay
stipulated by the import guidelines passes, I plan to proceed with the import.
Thanks!
