* C$ ends at C$1.0458 vs US$, or 95.62 U.S. cents * Fed official's comments boost greenback * Oil price slip hurts Canadian currency * Canadian bond prices fall By Alastair Sharp TORONTO, Nov 5 (Reuters) - The Canadian dollar weakened against its U.S. counterpart on Tuesday after a U.S. Federal Reserve official said 3 percent U.S. growth was within reach, while U.S. economic data also helped support the greenback and falling oil prices hurt the energy-linked loonie. Boston Fed President Eric Rosengren said relatively slow growth was easily imaginable and the Fed could keep interest rates near zero into 2016, but he added it is also possible that U.S. economic growth could near 3 percent by early next year. "That's more hawkish, so the (U.S.) dollar has just turned here," Steve Butler, director of foreign exchange trading at Scotiabank, said during morning trade. "That's really what kicked it off." The Canadian dollar ended the North American session changing hands at C$1.0458 to the greenback, or 95.62 U.S. cents, compared with C$1.0418, or 95.99 U.S. cents, at Monday's North American close. Also helping the U.S. dollar, the Institute for Supply Management (ISM) said U.S. service-sector business activity picked up in October and firms took on workers despite a partial government shutdown, though new order growth slowed for a second straight month. "The ISM data helped the U.S. dollar. There was also some focus on weakness in oil prices that could have helped to undermine the (Canadian) currency a little bit," said Mark Chandler, head of Canadian fixed income and currency strategy at Royal Bank of Canada. U.S. crude oil hit a four-month low on forecasts for rising supplies and continued weak demand. Currency traders are looking ahead to major U.S. economic data later in the week, which could shape opinion on whether the Fed will trim its monetary stimulus program. "Markets are almost willing to look at a soft number and explain it away...if it does come in firmer it may have more of an outsized reaction in both fixed income and currency markets," Chandler said. U.S. gross domestic product data for the third quarter is due on Thursday and will provide a measure of the momentum in the economy before last month's partial government shutdown, while jobs data for October is due on Friday. In the Canadian government bond market, the two-year bond was off 2-1/2 Canadian cents to yield 1.130 percent, while the benchmark 10-year bond fell 31 Canadian cents to yield 2.534 percent.
