TORONTO, Nov 1 (Reuters) - The Canadian dollar tumbled more than two cents against the U.S. dollar on Tuesday, slipping back below parity as fears over the euro zone debt crisis and the collapse of broker-dealer MF Global darkened the outlook for the global economy.

The fallout from the collapse of MF Global Holdingsalso rippled through global exchanges, as operators moved to suspend the U.S. futures broker or limit trades of its customers. [ID:nL4E7M10S3]
"All the things that could go wrong for CAD are going wrong at the same time here," said Camilla Sutton, chief currency strategist at Scotia Capital.
She noted that risk sentiment was also hurt by an unexpected fall in PMI data for China's manufacturers and an interest rate cut by the Reserve Bank of Australia. [ID:nL5E7M100M] [ID:nL4E7LV2ZI]
"The spike in risk aversion is really weighing on the near-term CAD outlook as is fears that China's growth is slowing faster than expected and the RBA might see ... softer growth in China."
At 8:11 a.m. (1211 GMT), the Canadian dollarstood at C$1.0149 versus the greenback, or 98.53 U.S. cents, down from Monday's North American session finish at C$0.9967 to the U.S. dollar, or $1.0033.
Earlier, it sank as low as $1.0174, or 98.29 U.S. cents, more than two cents lower than Monday's close to its weakest level in nearly a week.
Sutton expected the day's range for the currency to hold between C$1.0080-C$1.0180.
