I have just completed my most recent paper. It is a price index for Canada covering the period from 1688 to 1850. I use prices collected from the account books of religious congregations with estates throughout the modern-day province of Quebec. The consistency of the type of price quotations in the source material, the high frequency of observations for many goods, the vast number of goods and the inclusion of numerous non-agricultural and non-food goods represent a substantial improvement over previous indexes. Price trends are mildly different from those of existing, but less comprehensive, price indexes. This new index is used to link up with indexes post-1850 in order to create a 328 years-long price index for Canada.
