RE: House 001I used to work on the trading floor of the old TSE at 234 Bay St., so I have some knowledge.

That said, tmx.com says that trading number 001 is 'anonymous' and not the actual name of a brokerage house. I don't know how an actual trade like this would be executed if it's not done via a member company of the TSX.

To add to my previous post, as of today, EVERY retail investor who bought PV is now losing money. Over 99% of the trades were above the current price.
