* Firms to C$1.0269 vs US$, or 97.38 U.S. cents * Rises with North American equities, some commodities By Allison Martell TORONTO, June 12 (Reuters) - Canada's dollar firmed against its U.S. counterpart on Tuesday, helped by gains in North American equity markets and some commodity prices, including U.S. crude and gold. Both Canadian and U.S. stock indexes rose , paring some of the heavy losses seen on Monday, w hen investors worried about the effectiveness of Europe's plan to bail out Spanish banks. The Canadian dollar also weakened on Monday. "Part of it may have been a bit of an over reaction yesterday," said Mark Chandler, head of Canadian fixed income and currency strategy at RBC Capital Markets. "People were a little frustrated in the lack of details on the Spanish banking package, but when everything is said and done, it's obviously better that we get some sort of commitment." Chandler said the small bounce in North American equity markets and a modest rise in the price of some commodities also supported the resource-linked currency. U.S. crude and gold prices rose, and commodity prices were broadly higher, with the benchmark Thomson Reuters-Jeffries CRB Index up 0.1 percent. [. TO] [O /R] At around 1:30 p.m. (1730 GMT), the Canadian dollar was at C $1.0269 a gainst the U.S. currency, or 9 7.38 U .S. cents, compared with Monday's close at C$1.0312, or 96.97 U.S. cents. EUROPE FEARS LINGER With Tuesday's gains, the currency was little changed from Friday's close at C$1.0270, or 97.37 U.S. cents. A weekend deal by the 17-nation euro zone to lend Madrid up to 100 billion euros ($125 billion) for its bank rescue fund, more than an initial audit suggests it is likely to need, was aimed at reassuring investors and erecting a new firewall. But investors remained wary about the broader euro zone debt crisis. Concerns that the Greek election on June 17 would force a disorderly exit from the euro zone were rekindled by a report that EU officials were considering ways to manage the fallout. "Risk currencies are trading marginally better against their safe haven counterparts, but I think that doesn't necessarily speak to a larger trend. I think it's really just a consolidation move," said Greg Moore, foreign exchange strategist at TD Securities. Canadian bond markets were mostly lower across the curve. Canada's two-year bond fell 5 Canadian cents to yield 1.022 percent, while the benchmark 10-year bond dropped 43 cents to yield 1.806 percent.
