Canadian Patent Numbers 1824-2002

Research by Richard Cushing

Before 1870, Canada was administered as a colony of Great Britain. The British North American Act of 1867 established a federation of 10 provinces into the self governing nation of Canada.

There are two groups of Canadian patent numbers. One is pre-Confederation numbers issued during the years 1824 to 1870; the second group was issued after Confederation and were issued from 1869 to present.

There is a slight overlap of numbers issued during the transition from colony to federation during the years 1867 and 1870. Numbers 142 to 305 were issued out of sequence between 1831 and 1850.
