TORONTO - It would be a very different G20 summit if Paul Martin were still in charge.
The former prime minister says Ottawa has a responsibility to put climate change high on the agenda at the summit in Toronto.
Martin says in a speech the G20 is the world's new "steering committee" and can't just limit its actions to banking and economics.
He says climate change is a pressing concern for the world and the G20 needs to help ensure the success of international climate negotiations scheduled for December in Mexico.
He says the G20 should also tackle global poverty.
The Harper administration has limited the G20 agenda to banking regulations and economic stability, stifling other countries' attempts to add climate change and international development to the list.
