The Toronto stock market closed little changed after Germany and France called for a second emergency summit on the European debt crisis next week.

Leaders arranged for a second meeting Wednesday after it became clear that they would not be able to bridge their differences in resolving a problem that threatens the stability of global financial markets in time for the meeting Sunday.

There was also relief that the Greek parliament passed an austerity bill that includes more pay and staff cuts in the civil service as well as pension cuts and tax hikes for all Greeks, opening the way for a second round of bailouts to hopefully keep the country from defaulting.

“I think the measure buoyed the markets a little bit,” said BMO Capital Markets deputy chief economist Doug Porter, referring to the Greek vote which passed after two days of riots outside the country”s parliament building.

“I think there”s a bit more hope.”

The S&P/TSX composite index came back from a 151-point slide to close 19.17 points lower to 11,830.33 while the TSX Venture Exchange slipped 13.02 points to 1,512.79.

The Canadian dollar found lift following the two late-session developments, rising 0.5 of a cent to 98.52 cents US after earlier tumbling as low as 97.76 cents US.

U.S. markets ended the session mainly higher as the Dow Jones industrials gained 37.16 points to 11,541.78. The Nasdaq composite index was down 5.42 points to 2,598.62, while the S&P 500 index climbed 5.51 points to 1,215.39.

Investors had hoped that the weekend summit would produce a three-pronged solution to the debt crisis. That would include measures to boost the firepower of a bailout fund, a recapitalization of a large part of the banking sector and a plan to get the banks to take a bigger hit on their Greek debt holdings.

But hopes for something definitive from the Sunday summit in Brussels faded amid apparent disagreements within the eurozone over important parts of its strategy on Greece, banks and its bailout fund.

The French and German governments said that all elements of the eurozone”s crisis strategy would be discussed on Sunday “so it can be definitively adopted by the Heads of State and Government at a second meeting Wednesday at the latest.”

See-sawing expectations in recent days have resulted in the TSX swinging hundreds of points in either direction in daily trading.

Commodities have also seen huge swings because failure to tackle the debt crisis could result in a disorderly default by Greece, play havoc with the region”s banks and derail an already fragile economic recovery, which in turn would slash demand for oil and metals.

Goldcorp Inc. (TSX:G) faded 33 cents to $45.01 and Barrick Gold Corp. (TSX:ABX) was down 74 cents to $44.94.
