The info I'm about to say came directly Canada's Wonderland's general manager:
The B and M clause was that no B and M coaster could be built within a certain distance (I forgot the number) from Cedar Point exculding andy Cedar Fair park. At the time, CW wasn't owned by CF so wonderland had to settle with a SLC. Belive it or not, Wonderland was 2 miles away from getting the B and M invert.
I think the deal was only against Paramount though the manager never said who if it was for any park or just Paramount.
