Calgary City Council requested the provincial government hold an inquiry following the revelation MacKay borrowed 35 bags of city cement for personal projects at his home and failed to return the bags by fall of 1958, and in October 1958, Premier and Attorney General Ernest Manning ordered Judge L. Sherman Turcotte to hold an inquiry. The resulting report (Turcotte Inquiry) published in July 1959 outlined a number of improper gifts and benefits received during MacKay's time as Mayor of Calgary from individuals seeking public contracts or approvals from the City.
