This alert was assembled automatically from live official feeds the moment the change appeared, and is updated in place when conditions clear. It is a report of what the feeds say — not a substitute for the official source, and not navigational advice. Confirm anything that affects your passage directly with Parks Canada or the Canadian Coast Guard before you commit to it.
