TORONTO, April 26 (Reuters) - The Canadian dollar weakened against its U.S. counterpart on Thursday to approach the previous day's three-week low, weighed by a cautious Bank of Canada and as investors assessed the progress of talks to seal a NAFTA trade deal.

Canadian government bond prices were higher across the yield curve in sympathy with U.S. Treasuries as buyers emerged following a week-long selloff spurred by concerns about rising inflation and growing borrowing by the U.S. government.
