The Canadian dollar weakened against its U.S. counterpart on Friday, extending a weekly decline, as the greenback broadly rose and domestic data showed industries operating at a greater share of their capacity in the first quarter. The loonie was trading 0.3% lower at 1.2135 to the greenback, or 82.41 U.S. cents, after touching its weakest intraday level since May 27 at 1.2140. The U.S. dollar rallied against a basket of major currencies as U.S. Treasury yields stabilized.
