TORONTO, Nov 17 (Reuters) - Canada's main stock index rose on Friday as higher commodity prices helped resource shares, but losses from earlier in the week left the index on course to snap a nine-week winning streak.

* Gains for the index came as data showing a drop in Canada's annual inflation rate gave the Bank of Canada room to wait until next year to raise interest rates again. Before this week, the TSX had advanced for nine consecutive weeks, a feat not seen since late 1996.
* The materials group, which includes precious and base metals miners and fertilizer companies, added 0.9 percent, while the energy group gained 0.6 percent.
