WHALE WARNING FLAG
The Whale Warning Flag was first introduced around Northern Vancouver Island by the North Island Marine Mammal Stewardship Association (NIMMSA) as a means of addressing the growing number of negative interactions between vessels and humpback whales. By using the same flag design we are collectively promoting and strengthening a consistent message of Whale Wise boating behavior throughout the transboundary waters of the Salish Sea.
If You Have A Flag:
- When you encounter whales within 0.65 miles (1 km) of your vessel raise the flag.
- Slow down to 7 knots or less.
- Follow the regulations and Be Whale Wise Guidelines
- Turn off fish finders and/or depth sounders
If You See A Flag:
- Whales are within the vicinity of the boat or land station flying the flag.
- Slow down to 7 knots or less.
- Follow the regulations and Be Whale Wise Guidelines
- Turn off Fish Finders and/or depth sounders
- Observe the direction of travel of the whales and other vessels to determine the proper way to approach or depart the area

MARINE RESEARCH FLAG
This flag indicates that research is being conducted under a Marine Mammal License (MML) approved by Fisheries and Oceans Canada (DFO). There are specific conditions, responsibilities and reporting requirements associated with each license. If a vessel has this flag please stay away, as the research may involve approaching marine mammals closer than the minimum approach distance.
Note: as of June 1, 2026, whale watching and eco-tourism companies are no longer required to fly the Vessel Authorization Flag, as they are no longer required to obtain a Whale Watching Authorization in Canada per the 2026 Interim Order under the Canadian Shipping Act, 2001.
