Mt. Gox was the world's largest Bitcoin exchange until it's bankruptcy in 2014 due to an alleged hacking incident that cost hundreds of millions of dollars. Mt. Gox is a Japanese company but its customers were all over the world including many Ontarians.
In September a class action suit was partially certified but this week's Ontario Reports includes an October decision that stayed the suit:
"There have been two class actions commenced against MtGox in the U.S. The Trustee has obtained recognition of the Japan bankruptcy proceedings in the U.S. under chapter 15 of the U.S. Bankruptcy Code as a foreign main proceeding, resulting in an automatic stay of the U.S. litigation. The Trustee is entitled to the same relief in Canada relating to the class action filed in Ontario."
