TORONTO, April 21 (Reuters) - Canada's main stock index was nearly unchanged on Friday as SNC-Lavalin rose on an acquisition move and Home Capital Group recouped steep losses, while some miners and energy stocks weighed.
SNC-Lavalin Group Inc gained 2.1 percent to C$54.17 after the engineering and construction company said on Thursday it would move ahead with a planned purchase of Britain's WS Atkins Plc for C$3.6 billion ($2.67 billion).
Another influential gainer was Home Capital Group Inc , which jumped 14.9 percent to C$20.35 after the company announced preliminary earnings figures and released a message from its chairman.
The stock recovered from sharp losses on Thursday, the day after the company acknowledged a securities regulator's hearing into its disclosure practices.
The broader financials group was flat. Canada's annual inflation rate cooled more than expected in March, underscoring expectations that any interest rate hike would be a long way off.
At 10:28 a.m. ET (1428 GMT), the Toronto Stock Exchange's S&P/TSX composite index was down 0.86 points, or 0.01 percent, at 15,624.70. It was on track for a 0.5 percent gain for the week.
Seven of the index's 10 main groups gained, with advancers outnumbering decliners by a 1.5-to-1 ratio overall.
The energy group retreated 0.1 percent as crude prices slipped and another global player looked at pulling out of the country's oil sands, which are among the world's most expensive plays to develop.
BP Plc is considering the sale of its stakes in three Canadian oil sands projects, sources told Reuters, following similar exits from ConocoPhillips and Royal Dutch Shell .
Suncor Energy Inc declined 0.3 percent to C$40.52 and Encana Corp shed 0.6 percent to C$14.40.
Industrials fell 0.1 percent as Canadian Pacific Railway Ltd pulled back 0.9 percent to C$205.42 after its shares rose on Thursday on earnings that topped expectations.
The materials group, which includes precious and base metal miners and fertilizer companies, lost 0.3 percent, with First Quantum Minerals Ltd down 2.2 percent at C$13.15 and HudBay Minerals Inc off 2.2 percent at C$7.95. (Reporting by Alastair Sharp; Editing by Lisa Von Ahn)
