The Canadian dollar ended Wednesday at its lowest level in more than a month as oil prices pulled back on concern about the global economy.

The loonie dropped 0.40 of a cent to $1.0120 (U.S.), after last falling below that position on Aug. 30.

The currency was pressured by the latest non-manufacturing industries report from China which showed the weakest growth in more than a year and a half. The index slid to 53.7 in September from 56.3 in August, though readings above 50 indicate an expansion.

In the U.S., manufacturing data was more positive with the Institute for Supply Management, a trade group of purchasing managers, saying that its index of non-manufacturing activity rose to 55.1 in September, up from 53.7 in August.

"The latest increase continues the gently improving trend of recent months and took the index to its highest level since March," said Andrew Grantham of CIBC World Markets in a report.

"Although the index does not have a great record in tracking U.S. GDP, it is a further indication that growth should have picked up in the third quarter following a lacklustre second quarter."

U.S. payroll processor ADP reported that companies added 162,000 jobs in September, slightly better than consensus expectations, but down from August. The data indicates that economic growth isn't gaining momentum.

The data come ahead of the latest U.S. and Canadian jobs numbers, due Friday.
