A cry of frustration:

I do bimonthly runs of the worldwide coastlines
(http://metro.teczno.com/#coastline), and Canada seems to be a
recurring source of problems. What the heck is going on up there? I
consistently see new imports of what seems to be Canvec data screwing
up coastlines and making for some deeply broken renders:

Most of that junk in the Atlantic Ocean is newly introduced within the
last few weeks, and is making it difficult to get out a clean
coastline suitable for rendering. It shows up in the main OSM mapnik
tiles in Hudson Bay, too:

I've been trying to fix problems as I encounter them and I've managed
to fix invalid coastilnes around Baltimore, Houston, Tampa and the
dreaded Montréal area in an effort to generate a usable map of North
America, but this Canvec stuff is absolutely killing me.
