After completing his studies at Western Technical School, Yarwood worked full-time as a commercial artist while painting on weekends.
In the late 1940s, he painted landscape, and in the 1950s he evolved to abstract expressionism, often with architectonic shapes or forms reflecting motion rather than the spontaneous splashes of painters such as Alexandra Luke.
[3] By 1960, unhappy with his painting, he had turned to sculpture using found materials, then with metals such as welded steel, bronze, and cast aluminum, allowing him to create surface effects using acid.
[4] An exhibition of his sculptures was shown at Hart House (now the Justina M. Barnicke Gallery, Art Museum, University of Toronto), in 1967.
[15] In 1968 he produced Pines, a large bronze work commissioned by the Government of Ontario and installed on the lawn of the Macdonald Block at 77 Wellesley Street West.
