Krista Scharf

Krista Lee Scharf, also known by her married name of Krista McCarville (born November 10, 1982) is a Canadian retired curler from Thunder Bay, Ontario. McCarville is a four-time Northern Ontario junior champion, the 2003 Winter Universiade silver medallist, a four-time Ontario provincial champion, an 11-time Northern Ontario provincial champion, and a four-time Canadian national medallist.

During her junior career, Scharf competed at four Canadian Junior Curling Championships for Team Northern Ontario, skipping three times (2000, 2001, and 2002), and playing second once (1998). Throughout her women's career, Scharf has competed in the Scotties Tournament of Hearts, the Canadian women's national curling championships, ten times, all as a skip. Before 2015, Northern Ontario did not compete at the Tournament of Hearts separately from Ontario; Scharf represented Ontario four times at the championships (2006, 2007, 2009, and 2010), winning bronze in 2010. She has skipped the Northern Ontario team eight times (2016, 2017, 2019, 2020, 2022, 2023, 2024, and 2025), winning silver in 2016 and 2022. She has also competed in three Canadian Olympic Curling Trials, finishing in third place twice (2009 and 2021) and fifth place once (2017).

Scharf and her rink are known for doing well at major tournaments such as the Scotties and Olympic Trials, despite not playing many tour events. Their team mission has been to be the "best 'amateur' team in the World".
