OpenAI's Answer
The search did not yield specific information regarding a "David Dawson" who made contributions to Canadian postmodernism. It seems there may be multiple individuals named David Dawson, including an artist, an academic, and a choreographer, but none explicitly connected to the contributions to Canadian postmodernism based on the query results.
For discussions on Canadian postmodernism, you might want to explore the work of academics like Linda Hutcheon, who authored "The Canadian Postmodern." Linda Hutcheon is noted for her significant contributions to the understanding of postmodernism in Canadian context.
