Marjorie Smith was fifteen years old in 1922 when she enrolled at the Art Association of Montreal, taking classes from Randolph Hewton. When the school closed three months later, she entered the École des Beaux-Arts, and over the course of five years there, garnered numerous prizes. She attended the Monument National concurrently, and would later study with Edwin Holgate

It was in 1930 that Smith and her husband Jean Palardy went on their first painting trip to the Charlevoix region. Over the next decade, they spent long periods in the area, renting a house for two years, boarding with various families, and eventually buying their own summer house in Petite-Rivière-Saint-François. For two summers, they traveled around the region with the ethnographer Marius Barbeau, assisting him in his study of the Charlevoix culture. Immersed in the rural community, Smith drew great inspiration from the people she came to know. At the same time, she opened her door constantly, both in the Charlevoix and in Montreal, to many artists and intellectuals, including her closest friends Jean Paul Lemieux, Marian Scott and John Lyman, as well as Goodridge Roberts and Alfred Pellan.

In 1934, Smith embarked with Palardy on the first of many trips to Europe, traveling to France, Spain and England, where she took an interest in contemporary British artists. On such trips abroad, she produced numerous landscapes in pen and ink, watercolour and oil. In 1937, she held her first solo exhibition at Toronto’s Picture Loan Society; by then she was already signing her work Jori Smith. Two decades later, Smith withdrew from the exhibition scene following her separation from Palardy, and spent increasing periods of time traveling. She re-emerged in 1976 and continued to paint every day, even in her nineties.
