Caisse de Dépôt et Placement du Québec, a C$237bn (€163bn) Canadian public pension fund, is to testify before the Quebec Parliament over its investments in asset-backed commercial paper, following a liquidity crunch over the summer linked to the US sub-prime mortgage crisis.

The Quebec scheme is believed to be the largest investor in the portion of the Canadian market for third-party ABCP that is not run by the country's banks. Asset-backed commercial paper is a type of short-term fixed income instrument.
