LOL ... They already did when the Feds reduced their share by 2 % .... Ontario pass it on ? .... Nope !

All you do with added taxation is continue to build the underground economy. I don't know a single, independent private contractor, plumber, electrician, painter, carpenter, tile worker, stone mason / bricklayer, auto mechanic or printer who won't do work on a " cash - no bill " basis. The purchaser voids the HST and the seller dodges some income tax. The higher the tax, the more worthwhile the avoidance becomes.

If you can't match spending to revenue then sooner or later you will reach the " end game. " .... Check out Greece - social programs being clawed back because they are now unaffordable due in large part to interest costs , a massive untaxable underground economy and no future without begging their lenders for more cash and more time.

There is a chasm at the end of Ontario's yellow brick road.
