Provencher MP Vic Toews says his government had to act.He is referring to the announcement by the Finance Minister Tuesday night he will overhaul the tax system relating to income trusts.  Toews says a large number of corporations were taking advantage of the tax loophole on income trusts and that was shifting the tax burden to individuals.  He adds the government's move will ensure long term tax equity for everyone.  Meantime, Toews is pleased by the Finance Minister's announcements to allow income splitting for pensioners starting next year and an increase in the age credit amount for this year.  He explains the moves will ease taxes for seniors.
