Harmonizing Saskatchewan's taxes may have been the death blow that forced Grant Devine from office in 1991, said David McGrane, assistant professor of political studies at the University of Saskatchewan.
"If the experience in Saskatchewan tells us anything it's that McGuinty should be stepping very warily when it comes to harmonization, it is something that can be extremely unpopular," McGrane said.
Harmonization became one of New Democrat Roy Romanow's key issues as he campaigned successfully to overtake Devine as premier and it was promptly abolished after the election.
