Joshim Kakegamic was born at Sandy Lake, Ontario in 1952. He began painting as a teenager in the late sixties under the guidance of his Ojibwa brother-in-law, Norval Morrisseau, and Cree artist, Carl Ray who were holding workshops on local reserves.
He worked with Morrisseau and Ray when they held demonstration classes in schools across northeastern and southern Ontario. He participated in a group show in North Bay in 1969 followed by a series of shows in various venues in northwestern Ontario. He continued to paint in North Bay for two years before returning to Sandy lake.
After a month long workshop at Fanshawe College in London, Ontario Joshim began painting seriously. It was also in London that he was introduced to the possibilities of screen printing and later learned the technique at Open Studio in Toronto. With the help of his brothers Goyce and Henry and his father, David, he established the Triple K Cooperative in 1973. It was modeled after a company Daphne Odjig had set up in 1970 - Indian Prints of Canada Ltd.
In the 1970s and 1980s, he took part in a number of exhibitions throughout Ontario, other sites in Canada, as well as on a group show Woodland Indian Art Exhibition at Canada House in London, England and Lahr, Germany.
A major exhibition took place at Toronto's Aggregation Gallery in 1977.
In 1993, while on a rescue mission, Josh was drowned in a lake in northwestern Ontario.
Josh Kakegamic's work is in private and public collections in Canada and abroad including Simon Fraser University Art Center, the McMichael Canadian Collection, The Royal Ontario Museum and others.
