On March 9, 1964, the Hon. J. W. Pickersgill moved in the House of Commons the second reading of the Electoral Boundaries Readjustment Bill, a step of major constitutional importance which not only made provision for the first redistribution of Canadian federal constituencies since 1952, but provided that, for the first time, this task of redistribution would be taken out of the hands of parliamentary committees and entrusted to independent representation commissions. All this was long overdue and there was broad, if not unanimous, agreement that the creation of impartial representation commissions was a desirable reform. As Mr. Pickersgill said in the House next day:
The first and by far the most important of these [principles] was that we should not follow the pattern that had been followed in the first ninety years since Confederation, of having the readjustment of representation in this place done in this place by its members directly, but that it should be done by some body which would be as impartial as we in our collective ingenuity could provide and who would be as competent as we could find means to provide through legislation and subsequent appointment.
