The Canadian Lakehead Exhibition (CLE) is an annual regional fair in Thunder Bay, Ontario, Canada.

Similar in nature to the Canadian National Exhibition in Toronto, it features local and regional artisans and farmers, a midway, concessions and numerous other activities geared towards families and people of all ages.

The exhibition takes place yearly in early August and is held on the CLE grounds in the Intercity area.
