Because the PC and Liberal candidates were unpopular, community leaders asked Roman to stand as a "Coalition Candidate". Roman used the PC blue and Liberal red on his signs, and drew supporters from both parties.
Roman did not seek re-election to the House of Commons in 1988 but instead endorsed Micheal O'Brien as the Progressive Conservative Candidate. O'Brien was one of the community leaders who had convinced Roman to run as a "Coalition" independent in 1984. Roman was returned as mayor of Markham, defeating Carole Bell, who had succeeded Roman as mayor upon his appointment as York chairman in 1984. He was easily re-elected in the 1991 municipal elections.
Roman was instrumental in the design and construction of The Cathedral of the Transfiguration, a large Slovak Byzantine church built on open land in northwestern Markham.
