Hmm, regarding the tagging of the St. Lawrence: the Great Lakes should 
still be tagged as natural=coastline, otherwise they'll disappear at 
zoomlevel 5 and upwards. The St. Lawrence itself is barely visible, so 
that shouldn't be a problem. However, the tagging of big lakes in 
general is another topic, which has been discussed before.
