The currency had been in the red before the central bank said its key rate will rise by one-quarter point to 1.0 per cent.
Bank of Canada snapped traders out of their slumber on Wednesday with an unexpected decision to hike interest rates.
The Bank of Canada is now expected to commit to a more hawkish tone than the U.S. Federal Reserve, which has tempered its rate hike forecasts after recently disappointing data. At its previous meeting in July, the BoC raised its key rate for the first time in seven years, also by 25 basis points.

Particular focus will be given to the evolution of the economy's potential, and to labour market conditions. There has been a slight increase in both total CPI and the Bank's core measures of inflation, consistent with the dissipating negative impact of temporary price shocks and the absorption of economic slack.
Furthermore, the central bank said it would pay "close attention" to how the economy responds to higher borrowing costs, given households have accumulated record levels of debt.
