By 1963, costs had risen to over $73million for the plan. Metro, which was also constructing the Gardiner Expressway, Don Valley Parkway and Bloor–Danforth subway lines had fallen under the scrutiny of the Ontario Municipal Board (OMB) over its spending. The OMB had to approve the 1963 budget before Metro could. The Spadina was separated from the 1963 budget, and the OMB held hearings into the project. In submissions to the OMB, the townships of Forest Hill and York again objected. CCTTRA, and the CCTRA noted its objections. Allan Ackman, of the Wellesley-Bloor Street ratepayers asked "what compensation is there for all the people will be exposed to the deadly poisonous clouds of fumes from the cars on it?" The Cedarvale ratepayers had obtained the advice of Lewis Mumford on matters of town planning and stated that the expressway was of no use without the cancelled Crosstown. Publisher Allan Perly objected to Yorkdale being such a beneficiary. The Deer Park ratepayers objected on the increases of taxation. The OMB upheld the Spadina project. The OMB stated in its decision that the "sectional interest must give way to the public need of the larger area." On the issue of the ravine parklands, the OMB stated "The board should and does expect that any park land that may be lost to York Township as a result of this undertaking will be replaced, insofar as may be possible in the circumstances, by suitable alternative lands for that purpose."
