I'm not entirely qualified to work on the border, save for the short
segment I've researched out of fascination with the Hans Island dispute,
and the BC/WA border (which is a nice, round 49.0°N, terrain be damned!
 see

but I don't see a problem with moving back to where reality is.

I'm curious if anybody has a source for accurate information as to
Canada's ocean claim.
