HONOLULU, Hawaii - Organizers of an annual conference for people who manage more than $3 trillion in public sector pension funds say administrators are skipping this year's meeting in Hawaii to avoid the perception they're wasting money by heading to the island paradise.

WASHINGTON - A new government report details 87 shipwrecks — most sunk during World War II decades ago — that could pollute U.S. waters with tens of millions of gallons of oil.

Even so, the potential for pollution is less than scientists had expected. The report released Monday by the National Oceanic and Atmospheric Administration concludes "the scope of the problem is much more manageable than initially feared.... Our coastlines are not littered with 'ticking time bombs.'"

TORONTO - For decades visitors to the D-Day beaches on the northwest coast of France have looked out at the English Channel, taking in the journey made by Allied troops that marked a turning point in the Second World War.

TORONTO - A public relations expert suggests Rob Ford's decision not to host his weekly radio show on Sunday may indicate the Toronto mayor has yet to fully figure out how to respond to allegations he was recorded on video appearing to smoke crack cocaine.

OTTAWA - A look at the life and career of Ray Novak, Prime Minister Stephen Harper's new chief of staff:

A group that includes some prominent Canadian actors, writers and politicians is calling on Prime Minister Stephen Harper to change the name of Victoria Day.

Author Margaret Atwood, Green Party leader Elizabeth May and actor Gordon Pinsent are among those behind an online petition to rename the public holiday, which is celebrated on Monday, as "Victoria and First Peoples Day."

OTTAWA - The Harper government is spending hundreds of thousands of dollars advertising a program that does not yet exist.

Prime-time ads began airing this week during NHL playoff games — currently the priciest advertising real estate on the dial — that tout a new federal Canada Jobs Grant for training workers.

OTTAWA - Here is a timeline of the Senate audits controversy.

OTTAWA - A team of 15 Canadian soldiers has been dispatched to Kandahar on a month-long assignment to assess whether dozens of military containers are still seaworthy enough to be brought home.

Over 375 shipping containers full of military supplies remain stranded at Kandahar Airfield nearly 18 months after Canada's withdrawal from the war-torn province, and almost two years since combat operations ceased.

HEDLEY, B.C. - Adrian Dix was inside the Hitching Post Restaurant drinking from a mug stamped with twin six-shooters while outside on the old mining town's main street, with dusk starting to cover the mountaintops, his campaign workers were counting potential seats in what appeared to be a shoo-in win.

How many? Forty-seven? Fifty-three? Maybe even 60 seats.

OTTAWA - A growing number of Canada's car dealers are removing fuel-efficiency labels that the industry agreed to display on each vehicle under a voluntary deal reached with Ottawa 15 years ago.

Monday's Games

(All times Eastern)

GREENBURGH, N.Y. - Don't judge the New York Rangers by the scores of their two losses to the Boston Bruins.

According to coach John Tortorella, the Rangers played much better in the Game 2 blowout than in their overtime defeat in the series opener.

Looks like Skylar Diggins will have a new ride when she goes to Tulsa to join the Shock.

The former Notre Dame star tweeted her thanks to sports agency Roc Nation, backed by rap superstar Jay-Z, along with photos of a new white Mercedes she said the agency surprised her with.

SASKATOON - In most other years, London Knights forward Max Domi would probably garner more attention at the MasterCard Memorial Cup.

The son of former tough guy Tie Domi is expected to be taken in the first round of next month's NHL draft, but with the three top North American-based prospects all playing at the Credit Union Centre, the 2013 edition of Canadian Hockey League's showcase event is far from normal.

OTTAWA - Craig Anderson has returned to form just in time to give the Ottawa Senators a chance against the top seed in the Eastern Conference.

Anderson was a pivotal part of Ottawa's 2-1 double-overtime win over Pittsburgh on Sunday that cut the Penguins' lead to 2-1 in the best-of-seven second-round playoff series.

TORONTO - Given his numbers at triple-A Buffalo, Anthony Gose wasn't expecting a call from the Blue Jays.

When it came, he still didn't quite believe it.

TORONTO - It appears Bryan Colangelo is out as president and general manager of the Toronto Raptors, but he could be staying with the team in another capacity.

According to multiple media reports, the Raptors are negotiating with Colangelo to take on a corporate, non-basketball role with the team.

DUBLIN, Ohio - Guan Tianlang, the 14-year-old Chinese amateur who made history at Augusta National, is bringing his game to Jack Nicklaus' backyard.

Guan, who last month became the youngest player to make the cut in a major championship when he finished 58th at the Masters, has accepted an exemption to play at the Memorial Tournament next week.

PHILADELPHIA - Freddy Galvis and Erik Kratz each homered off closer Aroldis Chapman in the bottom of the ninth innings Sunday, rallying the Philadelphia Phillies past the Cincinnati Reds for a stunning 3-2 victory.

Chapman (3-2) blew his second straight save opportunity after converting his first eight chances this season.

SASKATOON - After being swept in the first round of the Western Hockey League playoffs, many questioned whether the host Saskatoon Blades even belonged at the MasterCard Memorial Cup.

They emphatically put those doubts rest with a gritty win over the Canadian Hockey League's top team.

OTTAWA - As good-luck charms go, fibreglass shrapnel isn't high on most hockey players' lists.

But it seemed to do the trick for Colin Greening, whose double-overtime heroics lifted the Ottawa Senators to a 2-1 win over the Pittsburgh Penguins on Sunday in Game 3 of their Eastern Conference semifinal series.

ARLINGTON, Texas - David Murphy's three-run shot was barely enough against Miguel Cabrera's three home runs.

Murphy put Texas ahead for good with a drive just over the wall in right field in the sixth inning, and the Rangers spoiled the second three-homer game of Cabrera's career with an 11-8 victory on Sunday night.

Sunday's Games

(All times Eastern)

OTTAWA - Colin Greening scored 7:39 into double overtime, and the Ottawa Senators rallied for a 2-1 victory over the Pittsburgh Penguins that cut their series deficit to 2-1 on Sunday night.

Daniel Alfredsson got Ottawa even 1-1 by scoring a short-handed goal with 29 seconds left in regulation, just after the Senators pulled goalie Craig Anderson for an extra skater.

ARLINGTON, Texas - David Murphy put Texas ahead with a three-run home run, and the Rangers spoiled a three-homer game from Miguel Cabrera with an 11-8 victory against the Detroit Tigers on Sunday night.

Murphy's shot just over the fence in right field gave Texas an 8-7 lead and answered a bases-loaded double from Prince Fielder that put Detroit up by two in the sixth inning after the Rangers had walked Cabrera intentionally even though first base wasn't open.

IRVING, Texas - Sang-Moon Bae watched anxiously after hitting his tee shot at the par-3 17th hole Sunday in the Byron Nelson Championship.

When the ball landed on the front edge of the green fronted by water, he bent his knees and leaned backward obviously relieved. He was only a few shots away from his first PGA Tour victory and a congratulatory hug from the widow of the tournament's namesake.

BOSTON - Claude Julien wanted his Bruins to play more aggressively in the third period. The Boston coach got his wish with the help of some shaky defence by the New York Rangers.

A rare rough day for goalie Henrik Lundqvist certainly helped, too.

SAN ANTONIO - The San Antonio Spurs opened the Western Conference finals resembling the past champions who've been there so many times before.

The Memphis Grizzlies looked like the first-timers still trying to adapt to their first conference finals appearance.

STOCKHOLM - Sweden became the first host country to win an IIHF World Championship in 27 years in large part because of the addition of Vancouver Canucks forwards Henrik and Daniel Sedin during the tournament.

Henrik scored the winning goal, assisted on a third goal and scored into an empty net in Sweden's 5-1 victory over Switzerland in Sunday's sold-out championship game at Globe Arena.
