Quote from : Death at SeaWorld: Shamu and the Dark Side of Killer Whales in Captivity Book

Orcas can be spotted from the shores of Seattle, Tacoma, Port Angeles, Bellingham, and the popular San Juan Islands in Washington State; and Vancouver, Victoria, Nanaimo, Campbell River, and other cities in BC. These venues not only offer easy access to the whales, they are scenic and pleasant places to live: Researchers who study orcas tend to gravitate more toward this region than, say, Iceland.
