Due to the increased presence of North Atlantic Right Whales in the Gulf of St. Lawrence, seasonal speed restrictions apply from April 28 to November 15, 2019 through a combination of a static speed zone and four dynamic shipping corridors.
Latest information on the speed limits applicable in the dynamic zones can be found below (*).
A. Static Zone:
Vessels to operate at 10 knots or less (speed over ground), except in the four dynamic sectors below.
B. Dynamic Sector Corridors
Vessels may proceed at a safe operational speed when the Government of Canada has completed one flight over the dynamic sectors in 7 days and determined that no whales are present in these areas. Information on applicable speed limits is continuously broadcasted to vessels by the CCG MCTS via Navigation warnings (NAVWARNs, formely known as NOTSHIPs).
As per the latest NAVWARN NW-Q-0870-19 (effective 0400 UTC on JUNE 1, 2019):
Sector A: Vessels may proceed at a safe operational speed
Sector B: Vessels may proceed at a safe operational speed
Sector C: Vessels may proceed at a safe operational speed
Sector D: Vessels may proceed at a safe operational speed
