We fished for many years in the Hakai Pass area and have had Orcas swim right through the boats very close by while trolling. They don't appear to be afraid of anything. If you see some a ways off and want a better look you can approach them at trolling speed and they don't seem to mind. Anything faster I am sure is frowned on by the Department of Fisheries and Oceans who can appear out of nowhere in seconds. Bottom line is watch but don't chase.
