The ECB is considering buying corporate bonds on the secondary market and may decide on the matter as soon as December with a view to beginning purchases early next year, several sources familiar with the situation told Reuters.

The Toronto Stock Exchange's S&P/TSX composite index <.GSPTSE> closed up 209.94 points, or 1.46 percent, at 14,547.71.

The benchmark TSX has rebounded 6.6 percent since reaching an eight-month low last week. It hit a one-week high on Tuesday.

"It's really a stimulus-driven rally today," said Youssef Zohny, portfolio manager at Stenner Investment Partners of Richardson GMP Ltd, which manages about C$28.3 billion in assets.

"We expect the market to be very volatile in the coming months, and we'll see volatility both ways," he said.

Still, Zohny expects the TSX to outperform the U.S. market.
