GATINEAU, Que. - Prime Minister Stephen Harper says Ottawa will finance a new centre for examining global security, based at the University of Toronto.

In a speech to business leaders from G20 countries, Harper said the Centre for Global Security Studies should help world powers better understand conflict, terrorism and cyber security.

Harper also urged G20 countries to put aside their differences and press ahead with stronger financial regulations that will cement the global recovery.

He spoke out against attempts by some countries to impose a global tax on banks, saying such a move would penalize Canadian banks in spite of their good performance during the financial crisis.

He said recent numbers show that Canada was the last of the major developed countries to be pulled into recession, and will be the first out -- something he had predicted at the start of the downturn.
