Canada's main stock index took a breather on Thursday after hitting record highs in the previous session, as weakness in commodity-related stocks were offset by gains in healthcare stocks.

At 10:05 a.m. ET (14:05 GMT), the Toronto Stock Exchange's S&P/TSX composite index was up 3.3 points, or 0.02%, at 20,590.62, with healthcare and industrial stocks among the top gainers, both up 1.8% and 0.4% respectively.

Both energy stocks and miners were among the biggest drags.

Recouping losses from last week, the benchmark index was set to record its seventh straight month of gains driven by heavyweight technology stocks, up 6.7% so far this month.

"The TSX appears poised to set new record highs... it has begun this week with many sectors re-accelerating and earnings coming in better than expected," said Brandon Michael, senior investment analyst at ABC Funds.
