The Bank of Canada's role on money markets is to establish monetary policy. It is responsible for keeping the short-term liquidity market running smoothly. That's how it implements its monetary policy. That's what it has committed to do ever since the crisis began.
They've provided more liquidity to the market and expanded the term over which they can provide liquidity. They've expanded collateral. As part of the budget bill, the statutes of the Bank of Canada are being expanded to give them the capacity to take broader types of collateral.
The Bank of Canada's mandate is to keep the system secure, but it is not responsible for the actions of individuals or companies.
