The Royal Commission of Inquiry on Constitutional Problems or Tremblay Commission was called for by the premier of Quebec, Maurice Duplessis in 1953. The commission, chaired by Mr. Justice Thomas Tremblay, studied the problem of tax sharing between different levels of government and greater constitutional problems in Canada.
The commission held 97 public meetings throughout Quebec, received 217 briefs, launched several studies, and finally published a five-volume report in 1956.
