There are a few inaccuracies in that article. Most of the 'charity casinos' of the 3 day floating variety were using really cheap crap. Hot stamped dice chips, unicorns etc were the most common. Some had stickers instead of hotstamps. A few were beat to shit hot stamped Paulsons. None that I remember were Paulsons with inlays. The 3 day floating casinos shut down when the permanent charity casinos opened. I have never seen in any quantity any of the floating casinos' chips come available and trust me, you wouldn't really want them. As you can imagine, none of the equipment of these casinos would be of any quality because they had to set up, operate for three days in some bingo parlour hall, banquet room or Polish club etc etc, then tear down, pack up, and open the next day in some other location across town. My wife and I played a lot of blackjack in those days and I can remember my wife waiting for me to come home with the paper so we could see where the casinos were operating that evening. Usually 3-4 Blackjack tables, roulette, a couple of other table games and a couple poker tables.
I did manage to acquire one of the BJ tables, which you can see is from Ace Casino games, which is the first operator listed in your link above.
The permanent charity casinos were all run by the government.
Up until recently we had 3 types of casinos:
a. commercial casinos - Caesar's Windsor - the only casino not operated by the government, Fallsview and Casino Windsor. These are the 3 largest in Ontario.
b. charity casinos, smaller, only a few had Cardrooms
c. Indian run casinos
Originally all the permanent charity casinos had their own logos on Paulson inlaid chips (as seen above), then the government decided to standardize all the chips and while the spot patterns remained unique to each casino, all the chips were changed out for similar inlays.
Recently the government has decided to get out of the casino operation business, and contract out the operation of all their charity casinos. The changeover has already occurred at the 1000 Island Casino in Gananoque. It has now been renamed Shorelines Casino Thousand Islands.

New chips (and new spot patterns)
The casino closest to me is one of the largest charity casinos, Brantford Charity Casino. It is not known when the changeover to the private operator is going to happen for this casino or any of the other charity casinos.
