I have learned only a little in the strange case of 6573401 Canada Inc.
The Federal Corporations Database entry lists the address of this company as 199 Bay Street, Suite 2800 Commerce Court West, in good old Toronto. It was incorporated on the 24th of May this year. It has one director, a gentleman named Thomas A. McKee. There is no financial information, nor any information as to parent or subsidiary companies. No sign of who owns the company.
Googling Thomas A. McKee turns up Thomas E. McKee, Thomas M. McKee, Thomas J. McKee (Junior) and Thomas K. McKee. No luck there.
I have petitioned Corporations Canada for contact information for Mr. McKee. Perhaps he will have the answers I seek.
More updates as events warrant.
