Atlantic

To comply with internationally agreed practices, Canada and the United States of America have agreed to eliminate overlapping coverage of Electronic Navigation Charts (ENCs). This new ENC coverage scheme will result in each country changing their areas of coverage, so that only one country's ENC would be available for any given area at a particular scale.

These changes to Bay of Fundy/Gulf of Maine coverage came into effect 0000 Coordinated Universal Time (UTC), on 26 July, 2012.

The following represents the ENCs that are affected by this project:
