Massive debt looms as major risk ten years after GFC, Canada Pension Plan president Mark Machin warns

Canada Pension Plan president Mark Machin says massive global debt looms as a significant risk ten years after the Lehman Brothers collapse sparked the global financial crisis. 

Mr Machin told the ABC's Peter Ryan that stimulus from central banks provided in the wake of the crash means highly leveraged governments and corporations will eventually need to repay their debt. 

Mr Machin is in Sydney as part of the Canada Pension Plan's $9.2 billion investment in the WestConnex toll road project.
