After completing his graduate studies, Zuck returned to NSCAD in late 1972, and taught in the school until 1979.

In 1975, he began to focus on small paintings as a reaction to the prevailing concept-oriented art at NSCAD.

[5] In 1997-1998, a major two-part exhibition was organized collaboratively by the MacLaren Art Centre in Barrie, which held a retrospective of drawings titled Tim Zuck: Still Life in Landscape, and the McMichael Canadian Art Collection in Kleinburg, which presented an overview of his paintings titled Tim Zuck: A Decade of Painting.

Zuck taught at the Alberta College of Art and Design from 2002 and was awarded Professor Emeritus status in 2015.

[7] In the late 1970s and early 1980s, his images of boats, houses and people expanded into a wider range of forms that concerned him.
