There are also seasonal factors at play, as the sudden burst of cold wintry weather across much of the populated northeast portion of North America has sent energy prices rallying.

"When the traders in Chicago look out their window and see snow," CMC Markets analyst Colin Cieszynski said, "the seasonal pick up in energy markets kicksoff."

"It is not uncommon to get this sort of rally in natural gas and heating oil this time of year," Cieszynski said.

In response, the S&P/TSX Composite Index finished up 175.84 points at 15,039.87, the index's first close above 15,000 since the spring of last year.
