Can you give more detail on what you are missing in the osm map and link to examples? That style is open, unlike.the others.

Well, for example compare:

OSM http://www.openstreetmap.org/#map=10/51.3825/-68.5375 (I don't see anything on the St. Lawrence River either...)

Mapquest http://mapq.st/18F1XnO

Looking at LARGE bodies of water away from populated regions, I'm seeing very few labels anywhere.
