Ontario's Finance Minister Dwight Duncan is dismissing the claims of federal Tories who say Ottawa had nothing to do with the province's decision to harmonize its sales tax with the G-S-T.
Duncan says some Tories are trying to have it both ways by encouraging provinces to move to a single sales tax, then speaking out against it when their constituents complain.
Ottawa provided the province $4.3 billion dollars to move ahead with tax harmonization.
