Poloz's speech comes after the central bank held interest rates steady last week as expected, while a speech from Deputy Governor Tim Lane on Thursday stuck to the bank's dovish message that it will be cautious in considering further increases. a focus on the labor market, Poloz is likely to talk about long-term trends and may not speak about current monetary policy, though he will field questions after the talk.
“It's something quite specialized, maybe longer-term in nature, it's not something that maybe lends itself to any particular reference to the current outlook for monetary policy,” said Shaun Osborne, chief currency strategist at Scotiabank in Toronto.
The central bank is also seen as unlikely to have changed its thinking on monetary policy so soon after its last meeting.
The loonie was nonetheless volatile against the U.S. dollar after data showed that U.S. consumer prices cooled in February and after U.S. President Donald Trump said he was replacing U.S. Secretary of State Rex Tillerson with Central Intelligence Agency Director Mike Pompeo. all about external drivers of the CAD at the moment I think, rather than internal drivers,” said Osborne.
At 9:13 a.m. EST (1301 GMT), the Canadian dollar CAD=D4 was trading 0.05 percent lower at C$1.2833 to the greenback.
