CANADA FX-C$ retreats after lower-than-expected factory sales data

TORONTO, Jan 20 (Reuters) - The Canadian dollar weakened to
a session low against its U.S. counterpart on Tuesday after
Canadian factory sales data fell 1.4 percent in November, double
the expected decline.
    The Canadian dollar touched C$1.2022 to the
greenback, or 83.18 U.S. cents, more than half a cent weaker
than Monday's finish at C$1.1947, or 83.70 U.S. cents.
