The World Curling Federation allots two spots at the World Men's Curling Championship to the Americas Zone, which are normally taken by Canada and the United States. However, the World Curling Federation allows for other member nations in the Americas Zone (i.e. Brazil) to challenge Canada and/or the United States for berths to the World Championships. As hosts, Canada received an automatic berth to the 2017 World Men's Championships. Canada finished higher than the United States at the 2016 Ford World Women's Curling Championship, and thus received an automatic berth to the 2017 World Women's Championships,[2] meaning Brazil was allowed to challenge the United States rather than Canada for a berth to the 2017 World Championships. This was Brazil's fourth men's challenge of the United States, after challenges in 2015, 2010 and 2009 proved to be unsuccessful. This was the first women's Americas Challenge.
