It would be very interesting to get the daily list of Buy-ins for this year on SLI. I find it hard to believe that while all those shares were short months back, how they could be filled so easily when very few were selling. IMO, there quite possibly could have been a surplus of shorts that were not settled for long periods, and these buy-ins should show that, if that were the case.

This is what the CDS is and who it is regulated by, notice the Bank of Canada?

Canadian Depository for Securities Limited (CDS)
Canada's national securities depository, Canadian Depository for Securities Limited (CDS), provides clearing and settlement services in support of trading in equity, fixed income, and money markets. CDS is owned by major Canadian chartered banks, members of the Investment Dealers Association of Canada (IDA), and TSX Inc. CDS is regulated by the Ontario Securities Commission, L'Autorité des marchés financiers (the securities commission of Quebec), and the Bank of Canada.
