The greenback has languished at an almost two-month low as signs of a softening U.S. economy on Monday boosted the case for earlier Federal Reserve interest rate cuts.
The Bank of Canada gathers a day ahead of a European Central Bank meeting on Thursday.
Canada's annual inflation rate slowed to a three-year low of 2.7% in April, prompting money markets to see an increased chance of an interest rate cut this month.
Markets price about an 80% chance of a Canadian rate cut on Wednesday and discount 65 basis points (bps) of policy easing by year-end.

The U.S. dollar index rose 0.19% to 104.36. It hit 103.99 on Tuesday, its lowest level since April 9.
"The main point is that markets are pricing the Fed to cut rates almost as much as the ECB," Barclays' Fiotakis said.
"The divergence in the fundamentals is not priced. However, the growth and inflation dynamics will make the Fed much less dovish than other central banks," he added, arguing he sees an opportunity for investors to go long dollars.
Markets were also closely watching Brent crude futures, which hovered near four-month lows on Wednesday.
"If low oil prices cause disinflation to become a global phenomenon again, we wouldn't expect more policy divergence, nor a weaker dollar, as this would trigger 'dovishness' everywhere," said Thierry Wizman, global forex strategist at Macquarie.

The Mexican peso steadied after dropping about 4% against the dollar and nearly 6% against the yen since the ruling left-wing Morena party was re-elected and, in coalition, within reach of two-thirds majorities in both Congress chambers.
Some analysts said expectations for greater government control over the economy weighed on the Mexican currency.
"President-elect Sheinbaum has signalled responsible fiscal policies and central bank autonomy," Macquarie's Wizman said, arguing that the selloff on Mexican assets looked overdone.
"The dust may settle soon, leading to a period of outperformance for the Mexican peso," he added.
India's rupee recovered from a seven-week low hit as election results showed voters had returned Narendra Modi to power by a much slimmer margin than expected.
