In 1960, his highly experimental work is chosen to represent Canada at the São Paulo Biennial. In 1965, at the request of Arthur Erickson, Smith designed two murals for Erickson's new Simon Fraser University campus building. The work, titled "Mosaic Mural", is permanently installed along the sides of the west academic quadrangle. For EXPO '70 in Osaka, Japan, he was commissioned by Arthur Erickson to create an artwork for the Canadian Pavilion.
