The S&P/TSX composite index closed 121.76 points higher to 11,545.69, with shares of nearly every major Canadian energy player higher.

The energy sector was up 2.2 per cent as investors speculated over other possible takeovers within the industry.

The January crude contract on the New York Mercantile Exchange closed the session down 36 cents to US$69.51 a barrel.

Meanwhile, Abu Dhabi's $10-billion bailout to Dubai gave markets a jolt of optimism. The debt repayments quelled fears that the emirate would default and signal a new round of broader credit problems.

"What we're seeing is continued small steps towards fixing in the financial system, towards strengthening the various places that are weak," said Kate Warne, Canadian markets specialist at Edward Jones in St. Louis.

"That certainly doesn't eliminate all the possible things that can go wrong, but every small step is a step in the right direction."

The New York-based bank was hardest hit by the credit crisis and rising loan defaults, receiving a total of $45 billion in government support. It only needs to pay back $20 billion because the remaining $25 billion was converted into a 34 per cent ownership stake in the bank earlier this year.
