April 24 (Reuters) - TSX was slightly higher as gains in Canadian National Railway's shares boosted industrial stocks and steadying gold prices lifted precious metals miners.
* At 9:41 a.m. ET (1341 GMT), the Toronto Stock Exchange's S&P/TSX Composite Index .GSPTSE rose 12.22 points, or 0.08 percent, to 15,564.28.
* CN Rail CNR.TO rose 1.2 percent, providing the biggest boost to Canada's main index. The country's largest railroad posted a fall in quarterly profit on Monday, but some analysts said its operational challenges were likely to ease this year. Also boosting the index was a 3.7 percent increase in Restaurant Brands International Inc's QSR.TO shares after the Burger King owner posted a better than expected profit.

Teck Resources shares were up 3 percent after the world's second-biggest exporter of steelmaking coal reported higher-than-expected adjusted first-quarter earnings as sales volumes climbed. Barrick Gold said it was done selling assets to cut debt and would instead use funds from future sales for growth or to pay dividends. Its shares rose 3 percent.
