Hm, Osmarender seems to have trouble with the coastline here. It gets the land/water bit backwards for a rectangular area.

Actually on further examination Osmarender gets a lot of the coastline around Montreal wrong. The whole tip of the island here is underwater including a lot of suburbs :)

Thats because the residential area and water body polygons have not been imported yet. This will further define what the land actually is.
If you like, i can send you the .osm file of the area so you can see what will be imported?
