Born and raised in Canada Erin McLeod started playing goalkeeper at age 12 almost by accident after an injury to the team's goalkeeper lead her to step into the box. Up to that point she had been playing midfield or striker but after one game in goal she never came back out. Her athleticism lead her to play all different sports growing up but they eventually narrowed to soccer and point guard in basketball. At the end of high school she had to make a choice between the two sports and decided to stick with soccer.

McLeod attended Southern Methodist University from 2001-2002 before transferring to Penn State University her sophomore year. She was a starter at SMU with the team winning the WAC Championship title in 2001. She was a WAC Defensive player of the week in 2002 after posting her fourth shut out of the season against Hawaii. Her first season with the Nittany Lions she split starts with Amanda Brown before becoming the sole starter. The Nittany Lions came away with a 19-2-1 record that season. In 2005 the team went 23-0-2 and McLeod earned All-American honors for the second year in a row. She had 11 shutouts on the year gave up only 20 goals.

Professionally she began playing for the Vancouver Whitecaps in the W-League in 2004. The Whitecaps won titles in both 2004 and 2006 while she was playing for the team. In 2009 she started playing for the Washington Freedom in the WPS appearing in 28 games. Then like many top women's players she went to play overseas and found herself playing for Dalsjofors GoIF in Sweden. When the NWSL started in 2013 she returned to the United States and began playing for the Chicago Red Stars. In 2013 she played in 16 games and earned 4 shutouts with a 70% save percentage.

She had her first call up to the Canadian National team in 2002 and has since earned 92 caps. She made the roster for the World Cup in 2003 but found her self on the bench through out the tournament. She played in two of the teams three matches in the 2007 World Cup. McLeod was a part of the qualifying campaign for the Beijing Olympics in 2008. She was in goal for the 2012 Olympics where Canada won the Bronze medal.

As the sole goalkeeper in Houston it is safe to say that she will be the last line of defense for the Dash going forward.
