Who is Jack Bush? On March 20, 2009, Canada Post began issuing a commemorative stamp honoring this famous Canadian painter. Born in Toronto, Jack Bush (1909-1977) was an abstract painter and a member of Painters Eleven, a group dedicated to promoting abstract and expressionist painting in Canada. He was a master of colour, and though he painted landscapes at first, he soon developed an abstract technique which gained acclaim. His aim was to share emotion in his paintings, instead of having people identify with exact images. He was made an Officer of the Order of Canada in 1976, one year before his death.
