June 23 (Reuters) - Futures tracking Canada's blue-chip stocks edged lower on Tuesday as oil fell on easing supply concerns, while gold prices dropped amid expectations that the U.S. Federal Reserve could hike interest rates.

September futures on the S&P/TSX index were down 1.2% at 6:45 a.m. ET (1045 GMT).

* Oil prices fell for a second straight session amid easing supply concerns tied to progress in restoring shipments through the vital Strait of Hormuz.

* Spot gold and silver declined 1.5% and 4.4%, respectively, as expectations of further Fed rate hikes lifted the dollar.

* The U.S. waived sanctions on Iran for 60 days from Monday after the first talks under a nascent peace deal, with U.S. President Donald Trump saying he will "do what I have to do" if Iran does not stick to its side of the agreement.

* Canada's S&P/TSX Composite Index snapped a three-day losing streak on Monday, led by metal mining shares, as investors assessed fragile U.S.-Iran peace talks and hotter-than-expected domestic inflation data.

* Meanwhile, e-commerce platform Shopify Inc (SHOP) will ban all vapes from its platform as soon as this week following pressure from a group of U.S. state attorneys general aiming to curb sales of illegal e-cigarettes online, according to two sources familiar with its plans.
