My info is second hand but I do a lot of business in Toronto. Some guys I trust and have been in hockey a long time imply there was a conflict among the organizations and greater Toronto no longer welcome. Has been a long while best I can tell..... prob like the EHF and E9 not playing each other, makes no sense for the kids but the business side overrules.
Fact: several foreign programs are banned due to cheating in past years. Would come with older kids just to win. Team Russia 05 team cheated and got caught with 04 kids playing.
Toronto teams don't go due to conflicts with the Q leadership. It's a board decision and Toronto refuses to buy their way in.
