With no team, no coaches and no organization, a group of high school players appealed to two local baseball enthusiasts to start a program. After the program commenced, the Souris Juvenile Cardinals were accepted into an intermediate level adult league in South Western Manitoba. Later, the team applied to enter the Manitoba Baseball Association Juvenile category playoffs.

The Souris Cardinals went on to win the Manitoba title by defeating the Carman Goldeyes in the semi-finals and the South-End Sioux in the championship final.

Following the provincial championship, Souris hosted the 1967 Western Canada Championships and captured the Western Canada title in front of 1000 local fans. Souris placed four players on the Western Canada Championship All-Star team.
