The Lethbridge & District Exhibition was first organized by a group of farmers, ranchers, and citizens to promote agriculture and commerce in the area.

In 1912, the City of Lethbridge hosted the World Dry Farming Congress at the exhibition grounds, which were expanded significantly for that event, and included a streetcar line from the CPR station.

Following the completion of the Agri-food Hub and Trade Centre, it was revealed that there had been significant financial mismanagement of the new building project, including non-compliant expenses and contracting works, resulting in a budget deficit of $6.4 Million per year.

Subsequently, the City of Lethbridge removed the CEO and Board of Governors and assumed responsibility operating the exhibition.

Roughly 950 events are held at the park every year, which attract over 850,000 visitors and provide $81 million in economic benefit to the city.
