Hi Terry,
Thanks for solving the mystery. Their fuzzy explanation is still a bit confusing, eh?
The Fisherman's Vests while not approved, will provide the required buoyancy, when inflated, to keep the user afloat. The Inflatable Fisherman's Vests offer 16 lbs of buoyancy when inflated compared to 15.5 lbs of buoyancy in traditional, inherently buoyant, personal floatation devices. The standard in Canada for approved vests or suspenders type inflatable PFD's is 150 Newtons or nearly 34 lbs.
They say "traditional, inherently buoyant PFD's" have a buoyancy rating of 15.5 pounds and then say "approved vests" in Canada must have a rating of 34 pounds ... so I'm guessing that their reference to "approved vests" actually means "approved inflatable vests" like their high-end SAR and industrial gear.
Hey, we don't live too far apart ... I'm about five kliks south of The Gap.
