Wyatt openly disagreed with Katz on several issues. He was the only cabinet member to oppose the creation of an Assiniboine Park Conservancy in June 2007, arguing that he could not support more private-sector control of the city's parklands. In September 2007, he broke with the mayor and voted in favour of a proposed commission into police conduct. He later criticized Winnipeg's decision to ban pesticides, describing it as part of a "national fad". He was strongly critical of Katz's decision to close the Disraeli Freeway for sixteen months in 2008, and to permit Canadian Pacific Railway queue-ups in the Transcona area. On one occasion, Wyatt argued that Katz was undermining Transcona's interests with these decisions, and accused him of supporting only "personal business friends or residents in places like South Tuxedo", an upscale south Winnipeg neighbourhood. Katz did not publicly reprimand Wyatt for these remarks, and kept him as a member of the municipal cabinet.
