Morrow quickly emerged as a leading ally of maverick left-wing Member of Provincial Parliament (MPP) Peter Kormos within the NDP caucus. Like Kormos, Morrow was a vocal opponent of the Rae government's decision to back away from its pledge to introduce public automobile insurance to the province. In 1993, Morrow, Kormos and Karen Haslam were the only members of the NDP caucus to vote against the Rae government's "Social Contract" legislation, which restructured the province's labour laws and introduced unpaid leave days for some workers.
