Cyber attack on curling websites
On January 14, 2011, four major curling websites (CurlingZone, World Curling Tour, Ontario Curling Tour, and Canadian Curling Reporters) went offline in an apparent cyber attack by hackers from China and Korea. The problem was found to be missing databases of painstakingly documented curling information dating back two years from primary and secondary backup systems. For many weeks, the four websites and any content supported by CurlingZone's software were unable to be accessed. The proprietors of the websites were forced to request the help of data recovery services to recover the lost data, which includes information on thousands of curling events both major, like the Olympics season, and minor. As a result of these presumed cyber attacks, the websites were switched to a new server and reloaded with whatever information was available at the time.

Capital One, the sponsor of the Grand Slam of Curling, the World Curling Championships, and various teams and bonspiels, stated a few days after the incident that they would match donations to CurlingZone to help the recovery effort and encouraged other curling-related businesses to donate money. However, people involved with CurlingZone and The Curling News expressed concern that much of the data is irrecoverable and may have disappeared forever. As of March, the websites are up and running, but the content from last year and many years preceding it are still missing.

In another event, the websites of U.S. and world curling governing bodies were attacked by sites in China and Korea. The attacks may be related to the attacks on the four major curling websites.

The Dominion MA Cup
The Dominion MA Cup presented by TSN was created for the first time for the 2010-11 season. The Cup is awarded to the Canadian Curling Association Member Association (MA) who has had the most success during the season in the CCA sanctioned events. Events include the Canadian Mixed, Men's & Women's Juniors, the Scotties, the Brier, Men's & Women's Seniors and the national Wheelchair championship.

The inaugural title will go to both Alberta and Saskatchewan. Both MAs finished with the highest number of points, in a tie. The tie breaking procedure is the best record between the two MAs in round robin games, but the two MAs split their season series 4-4.

Alberta did not win any national titles; it was runner up in three events, and finished in the top six in all events. Saskatchewan, on the other hand, won both junior events and the Scotties. Manitoba finished third, having also won three events (the Brier, the men's seniors, the national wheelchairs).

The Governors Cup was also awarded, to the Member Association who has seen the most improvement. It was given to New Brunswick.

Points are awarded based on placement in each of the events, with the top association receiving 14 points, then the second place team with 13, etc.

Capital One Cup
The Capital One Cup is a season-long competition that awards curling teams point values for their participation in Capital One Grand Slam of Curling events. At the end of the season, the men's and women's teams with the top three point values are awarded purse totalling CAD$170,000. The top-ranked team is awarded $50,000, the second-ranked team $25,000, and the third-ranked team $10,000.

The points are allocated as follows:

Retirements

 * Richard Hart, longtime third for Glenn Howard, retired from high-performance curling due to considerations regarding his career. Hart was the 1998 Olympic silver medallist as third under Mike Harris, and the 2007 Brier winner and 2007 World Champion as third under Howard. He also was the six-time Ontario provincial champion with Howard and won eight Grand Slams with Howard.
 * Blake MacDonald, longtime third and fourth for Kevin Koe, retired from high-performance curling due to his work schedule and family commitments. MacDonald was the 2010 Brier winner and 2010 World Champion with Koe, and also won the 2008 Canada Cup of Curling with Koe.
 * Kathy O'Rourke retired from curling after her team announced that they would break up. O'Rourke was a former Canadian Mixed champion and has represented PEI at 6 Scotties, including the 2010 Scotties, where she and her team were the runner-up to Jennifer Jones.

Careers on hiatus

 * Mark Nichols, longtime third for Brad Gushue, announced that he would be taking a hiatus from high-performance curling for the 2011–12 curling season in order to spend more time with his family. Nichols was the 2006 Olympic gold medallist as third under Russ Howard and the 2007 Brier runner-up as third under Gushue.
