You folks need to visit Toronto! I see more than a Pentax a week just walking around the lakefront tourist area, and even more than that when we have our Pentaxian get-togethers!
But really, maybe it's just this area of Canada or this city in particular. Even for used gear, if I compare the craigslist activity of my hometown of Chicago (about twice the size of Toronto):
chicago photo/video classifieds "pentax" - craigslist (and 25% is just people padding their listing with every camera brand)
...to Toronto:
toronto photo/video classifieds "pentax" - craigslist there must be twice as many people with Pentax up here! Plus, this stuff doesn't stick around forever, unless the joker has no clue about real prices (like the used K100D two-lens kit for $700!).
Truly, while I do see a ton of Canons and a few Nikons (weird that its inverted to your cruise), Pentax is a solid, if distant, third place. And I rarely see Sony DSLRs, but almost never seen an Oly in the wild here. Heck, I've seen more Leica M9s than Olympus digitals!
