mt,
Yes, if you speak with conviction on this site, you had better know what you are talking about. And I did pull Stephen Herrero's book off the shelf before posting, not only to check my facts but also to make sure I spelled his name correctly.
Re number of grizzly vs black bear attacks. Based on your link, I count 40 brown vs 30 black bear fatal attacks starting with the 1970's. Herrero used a ratio of 2:1 (brown to black) in the first edition of his book. I am more comfortable with my choice of words ("many more") than I would be with yours ("approximately equal"). You are hardly being generous including the Canadian Rockies and Alaska in the stats, since that is where most browns and grizzlies live.
Re "only old and weak black bears see people as food" I did not say that.
Re "the correct response to a grizzly response depends on the situation". The first thing you do is determine whether your attacker is a black bear or a grizzly. If it is a grizzly, it is probably not attacking you for food (I thought we agreed on that), and you should play dead. If it is a black bear (and not an obvious mother-with-cubs situation), then there is a high likelihood that you are being seen as a meal and you should fight back. This is what Herrero said in '85, and what everyone here in the Canadian Rockies believes today. Does the latest edition of Herrero's book contain different recommendations?
The triple-ziplocking-is-useless claim came from personal experience. I have seen a (black) bear sift through a food pack to pull out a triple-ziplocked pack of Nanaimo bars, ignoring all the dehydrated stuff packed alongside it. The takeaway here is don't bring odiferous foods into bear country at all. I will reiterate: triple-ziplocking is futile for animals who live by their noses.
Finally, I also stand by my claim that bear spray is probably unnecessary in canoe country. Your Wikipedia link lists zero fatal bear attacks in BW/Q and surrounding areas (ie all Minnesota, plus anywhere in the area of Thunder Bay - Kenora - WCPP etc.) for the time covered by their table (maybe 40 years of good data). I'm not saying it could never happen (there were two fatal attacks listed for Algonquin), but I am saying that since there are something like 100,000 camper-nights spent each year in Q alone, the chance of getting attacked by a bear in BW/Q appears to have a very, very low probability.
Everyone has the right to make their own decisions on which risks to accept in their lives and which ones to actively mitigate. Here is a link that might put your estimate of the chance of dying of a black bear attack in BW/Q in perspective, and help you decide whether to take the bear spray or the Chablis:
