TORONTO -- In a bid to shake up his slumping club, Toronto GM Brian Burke has picked up former all-star defenceman Dion Phaneuf from the Calgary Flames in a seven-player deal.

The Leafs also acquired six-foot-six defenceman Keith Aulie and winger Fredrik Sjostrom.

In exchange, Toronto gave up defenceman Ian White and forwards Matt Stajan, Nick Hagman and Jamal Mayers.

There are also reports that the Leafs are swapping goalies with Anaheim, sending Vesa Toskala and Jason Blake to Anaheim in exchange for J.S. Giguere and a first-round draft pick.

The six-foot-three, 214-pound Phaneuf has appeared in 55 games this season with Calgary, registering 10 goals and 12 assists with 49 penalty minutes. The Edmonton native is in his fifth NHL season -- all with Calgary -- after being selected ninth overall in 2003.

Burke called Phaneuf an elite player whom he tried to acquire earlier in the season.

"This guy's a warrior. He's got a cannon for a shot. He plays the game hard .. I want players who play the game hard because they're hard to play against," he said.

Phaneuf, 24, made the NHL all-rookie team in 2005-'06 and has twice played in the league's all-star game (2006-'07 and 2007-'08).

The move comes after Toronto lost a 5-3 decision Saturday night to the Vancouver Canucks to extend its winless streak to six games. The Leafs (17-28-11, 45 points) are tied with Carolina for last overall in the Eastern Conference standings.

The Leafs blew a 3-0 lead Saturday night, a loss Burke said had soured him but had not prompted the shakeup.

"These pieces were in place prior to yesterday," he said.

The 20-year-old Aulie is currently with the Abbotsford Heat of the AHL and the Leafs plan to keep him in the AHL with the Toronto Marlies. He won gold with the Canadian junior team.

"Excellent skater for a big man," said Burke. "This is a guy we coveted and had to work very hard to get him in the deal. We think he's going to be a real good NHL player down the road for a long time."

Sjostrom, taken 11th overall in the 12001 draft by Phoenix, was billed by Burke as a good skater and a fine penalty-killer. He has one goal and five assists in 56 games this season.

Asked about the status of Tomas Kaberle, Burke insisted he will not ask the defenceman to waive his no-trade clause.

Only Miikka Kiprusoff and Jay Bouwmeester (both at US$7 million) make more on the Flames this season than Phaneuf, who is at $6.5 million this year. Sjostrom is at $750,000.

Hagman makes $3 million, Stajan $1.75 million, Mayers $1.4 million and White $950,000.

Asked about the salary cap situation, Burke said it would "manageable" after the planned second deal.

"Right now it's like a new pair of underwear," he said. "It's uncomfortably tight."

Stajan had 16 goals and 25 assists in 55 games while Hagman had 20 goals and 13 assists in 55 games. White had nine goals and 17 assists in 56 games.
