The Canadian dollar weakened against its US counterpart on Friday, unwinding much of this week's gains after data showing a slump in domestic jobs suggested the economy was not as resilient as the Bank of Canada had hoped.

The Canadian job market lost 71,200 net positions in November while the unemployment rate rose to 5.9%, the highest in more than a year, data from Statistics Canada showed. Analysts had forecast a gain of 10,000 jobs.

At 3:51 p.m. (2051 GMT), the Canadian dollar was trading 0.6% lower at 1.3259 to the greenback, or 75.42 US cents. The currency, which notched a four-week high on Thursday at 1.3158, traded in a range of 1.3173 to 1.3270. For the week, the loonie was on track to rise 0.1%.
