While I'm not responding to this quote, I would like to respond to one of your other posts in this thread that I cannot find. I am paraphrasing, but you responded to a comment about the orca being important for indigenous history, and then posited that indigenous history is relevant throughout all of Canada, and then used Montreal as an example.
I think you're forgetting the orcas significance to the pacific north west. The orca is much more prevalent in the pacific ocean than the atlantic or arctic.
"Killer Whales are the most widely-distributed mammals in the world. Although they are more commonly found in areas associated with high ocean productivity, in the mid to high latitudes, they can tolerate temperature ranges from polar to tropical waters. In Canada, Killer Whales are found in all three oceans, but are less common in Atlantic and Arctic regions. In British Columbia, they have been observed throughout almost all marine waters, including long inlets, narrow passages and deep embayments, as well as occasionally up brackish river channels."
