The HST is a big step closer to reality for Ontario.
The House of Commons voted 253-37 on Wednesday in favour of a harmonized sales tax for the two provinces.
The Conservatives, Liberals and Bloc Quebecois supported the measure, while the NDP opposed it.
All three local Conservative MPs — Larry Miller, Ben Lobb and Helena Guergis voted in favour of the harmonized sales tax.
Just hours earlier, the Ontario legislature passed its own legislation despite protests from the opposition parties.
The Senate will now deal with the federal HST bill, which transfers money to the two provinces for making the change.
