In this paper we construct historical data series beginning in 1871 fo
r Canadian M1, M2, and monetary base. The new series are at a monthly
frequency and use the Bank of Canada's definition of the monetary aggr
egates. institutional and reporting changes, however, make perfect bac
kwards extrapolation of the Bank's series impossible: there are only e
nd-of-month data rather than average weekly (since January 1994, daily
) data, and we cannot precisely match savings accounts (at chartered b
anks and trust companies) that are included in the modern monetary agg
regates. Our adjustments for these changes and their impact on the agg
regates are documented.
