Ontario to Follow the U.S. in and out of the Dark

TORONTO — Ontario will follow the United States and extend daylight saving time to stay in lock-step with its major trading partner, Canada 's most populous province said Thursday.

Starting in 2007, the province will change clocks on different dates in the spring and the fall.

Clocks will move forward one hour on the second Sunday in March and return to standard time on the first Sunday in November. Daylight saving time currently starts on the first Sunday of April and ends on the last weekend in October.

"It is important to maintain Ontario's competitive advantage by co-ordinating time changes with our major trading partner, and harmonizing our financial, industrial, transportation and communications links," said Ontario's attorney general, Michael Bryant.

"This is in the best interest of Ontario."

The United States approved an energy bill this summer that will extend daylight saving time in 2007 to save the equivalent of thousands of barrels of oil a day.
