cuts in Norway and Taiwan.
    The loonie, which broke through C$1.34 during the session,
echoed losses among other commodities-linked currencies.
    Norway and Taiwan's central banks both cut their benchmark
interest rate on Thursday. Taiwan's move, the first since 2009,

C$1.3347, or 74.92 U.S. cents on Wednesday.

74.53 U.S. cents, on Thursday.
    * Data showed that U.S. business investment plans fell
slightly last month, while the number of Americans filing for
new jobless benefits was little changed last week.
    * Investors await a speech later on Thursday by Federal
Reserve Chair Janet Yellen. A reiteration of Fed remarks from
last week on global growth worries could trigger further losses.
    * Canadian government bond prices were higher across the
maturity curve, with the two-year price up 5.7
Canadian cents to yield 0.495 percent and the benchmark 10-year
 rising 59 Canadian cents to yield 1.428 percent.
