TORONTO -- North American stock markets ended the day deep in the red in the wake of a vote by Britain to leave the European Union.

The vote left markets around the world bloodied amid concern that fallout from the decision will hurt global economic growth.

The Toronto market plunged at the start of the trading day before regaining some ground lost by the closing bell.

The S&P/TSX composite index ended the day down 239.50 points at 13,891.88. The Canadian dollar fell 1.37 U.S. cents to 76.93 cents US.

In New York, the Dow Jones industrial average plunged 610.32 points to 17,400.75, while the S&P 500 dropped 75.91 points to 2,037.41. The Nasdaq composite lost 202.06 points to 4,707.98.

In commodities, the August contract for North American benchmark crude oil fell $2.47 to US$47.64 a barrel, while the August natural gas fell 4.3 cents to US$2.694 per mmBtu. Gold was the lone bright spot as the August contract gained $59.30 to US$1,322.40 a troy ounce.
