* Canadian dollar at C$1.3372, or 74.78 U.S. cents * Bond prices mixed across the maturity curve (Adds details, quotes, updates prices) TORONTO/OTTAWA, Nov 27 (Reuters) - The Canadian dollar weakened against a broadly firmer greenback on Friday, pressured by a drop in crude oil prices amid fresh volatility in Chinese stocks, while Canadian producer prices fell more than expected. Crude oil futures fell as disappointing Chinese data and worries over a global energy supply glut overshadowed geopolitical concerns. The Canadian dollar has been hit this year by the drop in the price of oil, a key export for the country. Oil was also pressured by a drop in China equities after Reuters reported the stock regulator had widened its probe on brokerages to include the country's fourth-biggest securities firm. With oil down, "we're seeing the loonie take it on the chin," said Rahim Madhavji, president at KnightsbridgeFX.com. The Canadian dollar ended the North American session at C$1.3372 to the greenback, or 74.78 U.S. cents, weaker than the Bank of Canada's official close of C$1.3294, or 75.22 U.S. cents. Volume was subdued the day after the U.S. Thanksgiving Day holiday. On the domestic front, Canadian producer prices fell 0.5 percent in October, a bigger drop than expected and the third month of declines in a row. After a relatively quiet week, investors face a slew of domestic economic data next week, including figures on economic growth, trade and the labor market. The Bank of Canada will also make an interest rate announcement, though the central bank is widely expected to hold rates at 0.50 percent. But investors are likely to be more focused on Friday's jobs report south of the border with its implications for a potential U.S. interest rate hike in December, said Madhavji. "While those (Canadian) events can be significant catalysts, for the most part, the elephant in the room is still the Federal Reserve and interest rates," he said. Canadian government bond prices were mixed across the maturity curve, with the two-year down 1 Canadian cent to yield 0.631 percent and the benchmark 10-year rising 6 Canadian cents to yield 1.568 percent, having hit a three-week low at 1.547 percent ahead of December 1 coupon and maturity payments. Canada-U.S. spreads narrowed as Treasuries firmed following the U.S. Thanksgiving Day holiday, with the 2-year spread at -29.5 basis points and the 10-year spread at -65.4 basis points.
