At the 2005 Scotts, she caught the attention of many by winning the Ford Hot Shots competition and defeating defending champion Colleen Jones in the first draw.[9] After falling to a record of 2-4, she rallied by winning four of her next five games, finishing 6-5. This was enough, however, to get into a four-way tie for fourth place.[10] Hanna would end up winning both of her tie-breakers, against Cathy King of Alberta and Sandy Comeau of New Brunswick, allowing her to make the playoffs.[11] She then proceeded to defeat Stefanie Lawton of Saskatchewan in the 3 vs. 4 game, followed by Kelly Scott of British Columbia in the semi-final, to face the Jennifer Jones rink from Manitoba in the final.[12] At this stage, Hanna's team played well, and led for most of the game, but lost on the last rock to Jones' game saving in-off for four points.[13] Hanna was named the tournament MVP, and was chosen for the second all-star team.[14]
2005–2015
In March 2005, Hanna announced that her team's spare player, Joëlle Sabourin, would replace Letendre as the team's third, producing the same lineup they had in 2003-2004. Letendre was supposed to be the new spare, but had decided to form her own team.[citation needed]
The new Hanna team started the 2005-06 season well, with their first ever Women's Tour victory, winning the Autumn Gold Classic in Calgary, Alberta on October 17, 2005.[15] The total winnings for the team were $14,000. At the Ontario Scott Tournament of Hearts, however, Hanna's team lost in the quarter-final to two-time World Champion Marilyn Bodogh.[16]
In February 2006, the team acquired a new player for the following season, Chrissy Cadorin of Guelph, Ontario. Cadorin, who had skipped her own team for a number of years would play third, while Sabourin would play second. Dawn Askin became the team's Alternate, citing her desire to focus on her new career.[17]
The 2006-2007 season was not as successful as the previous two for the Hanna team. After not winning any major bonspiels, the team did have some success at the 2007 provincial championship. After finishing in first place after the round-robin, they lost both of their playoff games.[18]
Hanna played the 2007-2008 season while pregnant. Once again, the team qualified for the provincials, but lost in the tie-breaker match to Janet McGhee.
After the 2007-08 season, Cadorin left the team to form her own team. Steph Hanna was then promoted to third, and Merklinger to second, adding Lauren Mann as lead. Mann would be replaced by Lisa Weagle later on in the season. The team once again did not perform very well in the season's curling tour. However, they once again were able to make it to the provincial championship. The team, which was bounced from Regions, came through by winning the last chance Challenge Round, qualifying them for the 2009 Ontario Scotties Tournament of Hearts. At the 2009 Ontario Scotties, the team finished the round robin with a 5-4 record, and lost in their tie-breaker match to Alison Goring.
In 2009, Team Hanna shuffled once again. The team brought Toronto-area curler Kelly Cochrane in at third and Trish Scharf at lead. Sister Stephanie was bumped from third to second. The team made it provincials once again in 2010, but finished with their worst record, 4-5.
In March 2010, Hanna announced she and her sister would be taking the 2010-11 curling season off.[20]
At the conclusion of the 2011-12 season Hanna announced she would not be curling competitively in the 2012-13 season, and had no immediate plans to curl competitively in the near or immediate future. Her sister Stephanie also left competitive curling.[22] However, the Hanna sisters and Letendre teamed up with Lisa Paddle to curl in the 2013–14 curling season.
2016 Scotties run
After taking another season off, Hanna returned to competitive curling for the 2015–16 curling season, this time with Letendre as the team's alternate, Brit O'Neill at third and Karen Sagle at the second. Hanna qualified for her first provincial championship in four years, by winning the B-side of the last chance East qualifier for the 2016 Ontario Scotties Tournament of Hearts. The team shocked the curling world by winning the event, having to defeat their club mates, the World #1 ranked Rachel Homan rink in the final. At the 2016 Scotties Tournament of Hearts, the rink would again post a 6-5 record, however this time it would not be enough to make the playoffs. On March 7, 2016, Hanna again announced she would be stepping back from the game, citing a desire to focus on her work and family.[23]
