(Reuters) - Futures linked to Canada's main stock index tumbled on Thursday, pulled down by declines in oil and metal prices, while investors assessed the possibility of more rate cuts by the Bank of Canada after easing its policy for the second time this year on Wednesday.

The S&P/TSX 60 futures were down 0.69% as of 07:00 a.m. ET (1100 GMT).

Despite the market support offered by the rate cut, the Canadian benchmark index fell to a near two-week low on Wednesday due to declines in technology shares that mirrored tech megacaps selloff on Wall Street.

The Canadian central bank trimmed its key policy rate by 25 basis points, in line with market expectations, and indicated a possibility of more cuts if inflation continues to ease in line with forecasts.

Traders currently see a 62.2% chance of a cut in September.
