Julia Adelsheim was scanning the waters near Vancouver when she captured the moment: T063, a transient orca known to researchers, lunging through the surface in a powerful breach, chainsaw-like teeth flashing in the sunlight. It’s a sight that would have been rare decades ago, but today, whale watchers along B.C.’s coast are witnessing a quiet miracle—hundreds of days each year now host killer whales, humpbacks, and even starving gray whales in inland waters once devoid of their presence. This resurgence isn’t accidental. It’s the result of conservation victories, ecological memory, and, in some cases, a desperate search for survival.
The return of whales to Vancouver’s waters signals both hope and urgency. A 2023 study in Marine Mammal Science found that transient killer whales now patrol the Salish Sea on roughly 250 days a year—more than two-thirds of the calendar. Their comeback follows the recovery of seal and sea lion populations, once decimated by culling but now thriving thanks to legal protections. As these prey rebounded, so did the apex predators that depend on them. Meanwhile, humpback whales, wiped out in B.C. waters by just three years of commercial whaling between 1907 and 1910, are relearning ancestral feeding routes. After a century-long absence, they’ve returned in growing numbers, drawn by rich summer supplies of krill and herring.
But not all whale visits are cause for celebration. Gray whales, normally seen along the outer coast, are increasingly appearing in urban waters like Vancouver’s—not to feed, but to survive. These migrations are becoming desperate detours. Pregnant females need to consume between 1,600 and 1,900 kilograms of amphipods daily to sustain their calves and fuel migration, yet climate change is unraveling the Arctic food web. Shrinking sea ice means less algae, which means fewer amphipods. Emaciated whales are now stopping in southern waters, searching for alternative food, and too many are not making it. Several have washed ashore dead, victims of starvation in a warming world.
For those on the water, the message from UBC whale researchers is clear: admire, but do not disturb. Boaters, kayakers, and paddleboarders must slow down and stay alert—whales can surface without warning. Federal regulations require vessels to stay at least 100 meters from most whales and 200 meters from orcas, but true protection begins with awareness. Every sighting is a reminder of how far these species have come—and how fragile their future remains.
The whales’ return is not just a local phenomenon; it’s a testament to what thoughtful conservation can achieve. Yet it also underscores the cascading impacts of climate change. As the ocean transforms, these majestic visitors are both our teachers and our warning signs—inviting us to protect not just individual species, but the entire web that sustains them.
