Sanna Kannasto (née Kallio; 1878–1968) was a Finnish Canadian labour activist and feminist.

With A.T. Hill and Aku Päiviö she was one of the key figures in the Finnish Canadian socialist movement of the early 1900s.

Kannasto travelled across the country at least five times and made a large number of shorter journeys.

She spoke to the Finns in the remote mining towns, rural areas, and lumber camps.

[2] She was forced to leave her political activities in the early 1930s due to the continuous harassment by the Canadian authorities.

It is a story about union organizers and Finnish refugees who fled to Canada after the 1918 Civil War.
