It is only since the War that federal-provincial financial relations have received serious attention. In the years up to 1914 there was much petty bickering about better terms, but most of this was political by-play. The growth of Dominion and provincial expenditures was at about the same rate, and the distribution of functions and fiscal resources between the governments appeared to be in balance. The War was responsible for a major dislocation. The Dominion was forced to reach into the field of direct taxation and since 1921 the balance of fiscal superiority has swung heavily in its favour.
During the post-War decade 1919-29 the Dominion proceeded to liquidate some part of its War debt, and, while reducing rates of taxation, it did not feel able to relinquish its hold on any important sources of revenue. The trend of Dominion expenditure and debt was slightly downward. But, as everyone knows, the trend of provincial expenditure and debt was sharply upward. Ordinary provincial expenditures were $76,404,000 in 1919 and $177,542,000 in 1929 (an increase of 132 per cent.), while bonded debt and treasury bills amounted to $304,146,000 in 1919 and to $895,334,000 in 1929 (an increase of 198 per cent.). The increase in the burden of the debt was greater than these figures indicate, because interest payments grew from $11,926,000 in 1919 to $41,207,000 in 1929 (an increase of 245 per cent.). It is not possible to show in detail for what purposes the increase in expenditures took place. Ordinary expenditures can, of course, be analysed and it will be convenient in considering them to omit expenditure for interest. Ordinary expenditures (omitting interest) rose by 112 per cent, from 1919 to 1929. But there was great variation in the rate of increase of the principal items. Thus ordinary expenditure for highways and bridges rose by 152 per cent., for education by 145 per cent., and for welfare functions by 154 per cent. All other items increased only by 78 per cent. In this remainder is expenditure for such purposes as legislation, legal administration, and civil government, which rose by 34 per cent., 69 per cent., and 83 per cent. respectively.
