He exhibited in the Vancouver Art Gallery's B.C. Artists exhibitions. He had solo exhibitions at the gallery in 1940, 1952, and 1956.
He exhibited artwork under the name "Korner" instead of "Koerner" for a while, so that his work was not necessarily linked directly to the name of his wealthy family.
Koerner was on a list titled "Leading Vancouver Artists," provided to the Labour Arts Guild on April 10, 1946 by the Vancouver Art Gallery to assist in the Guild's call for entries to the second annual B.C. At Work exhibition.
He exhibited in the Seattle Art Museum's annual Northwest Artists exhibitions from 1953 to 1963.
He taught drawing and painting at the Vancouver School of Art from 1953 to 1958, and was a Professor of drawing and painting at U.B.C. from 1958 - 1962.
Koerner died in 2014 at the age of 100.
