Canada CHS update in the Marine GeoGarage

As our public viewer is not yet available
(currently under construction, upgrading to Google Maps API v3 as v2 is officially no more supported),
this info is primarily intended to our B2B customers which use our nautical charts layers
in their own webmapping applications through our GeoGarage API.
