To prevent the death of North Atlantic right whales by vessel
strikes, since June 26, 2019, the Government of Canada has
implemented temporary mandatory speed restrictions for all vessels
20 meters or more in overall length to travel at a maximum of 10
knots in certain parts of the western Gulf of St. Lawrence.
This temporary measure is in effect in addition to the speed restrictions implemented on April 28,
2019 and failure to comply with either may result in a fine of
up to C$25,000 (approx. US$20,000).
