Canada's largest natural gas producer caught the markets by surprise on Wednesday.

EnCana announced a net profit of $962-million in the first quarter of 2009.

The profit is a ten-fold increase over the same period last year.

The company says the strong performance comes from locked in long-term prices for its natural gas.

The locked in price is two-and-a-half times the current market rate for the commodity.

The good news saw EnCana's shares jump by over four percent on the Toronto Stock Exchange on Wednesday.
