Newman is running against fellow CSA vice-president Victor Montagliani and incumbent president Dominique Maestracci.
The election is part of the CSA's annual general meeting in Ottawa on May 5.
In a joint statement, the pro clubs say Newman is committed to reforming how the sports' governing body in Canada is structured.
The statement says: "We're confident that Rob is the individual best suited to complete the required reforms, and deliver on a viable national vision for the sport."
The pro teams will have a vote in the weekend election.
