Despite Finance Minister Jim Flaherty’s assertions that the income trust tax decision is final, given the political reality of a minority government that has yet to pass the tax levy into law, the trust saga isn’t over yet.

The Liberals and the Bloc have teamed up to vote on whether to call witnesses in parliamentary hearings on the issue. The Bloc is demanding that the four-year tax holiday be extended to ten and the Liberals want to find out if there is any tax leakage due to trust conversion by corporations.

The Tories had probably hoped that the tax would be forgotten by now and the general public will focus their attention on tax-cuts in the upcoming budget. Instead, income trusts promise to linger in the media limelight and could become an issue in a possible spring election.

The Conservatives won the previous election partly due to the controversy surrounding the leakage of the income trust decision of the previous government. It would be ironic if the Tories lose the next one due to investor anger over their own income trust decision.
