In preparing the first edition of Taxation in Canada Mr. Perry drew on his experience of over fifteen years of close association in the federal Department of Finance, Ottawa, with the formulation of Dominion tax policy and the drafting of tax laws. He was also directly involved in the negotiations and execution of the tax rental agreements between the Dominion and provincial governments, which give him an intimate knowledge of the provincial tax structure in Canada as well. Mr. Perry's study of taxation has also benefited from his nine years' association with the Canadian Tax Foundation; he became its Director and Chief Executive Officer in 1954, and the exercise of his duties kept him in close contact with the tax problems of the business community and of governments throughout Canada. Since March 1961 Mr. Perry has been Executive Director of the Canadian Bankers' Association. A number of special assignments have come to Mr. Perry in recent years. In 1953 he was sent by the Colonial Office to Nigeria, in 1958 he visited Ghana on a mission for the United Nations, and in 1959-60 he prepared a survey of the budgeting system of the Province of Newfoundland.
