"Work together", in bank-speak: Staff the infrastructure bank with friends from industry and shift private risk to the public treasury. 

The BoC was designed in 1934, in part, to make national investments. It provided zero-interest loans for construction of St. Lawrence Seaway, Trans-Canada Highway and other important national projects. Today, the federal government supports the Province of Newfoundland and Labrador with interest-free loans. 

Prior to the crisis, global bankers got OSFI to accept worthless 'liquidity agreements' to support ABCP in Canada. The IMF and their banking friends know now, like they did then, that the BoC is in reserve should their fanciful financings go offside, which they are designed to do. It was the BoC riding to the rescue in 2008 with the CLAF, an uneconomic loan (bank-speak: interest-free loan), to bailout troubled banks. 

Warning: International banking is accountable to no one. Basel is a talk shop. Private gain; public sacrifice.
