When did sir oliver mowat become a father of confederation?

Sir Oliver Mowat became a Father of Confederation during the 1867 Confederation process in Canada, where he was a key advocate for the inclusion of Ontario (then Canada West) in the new Dominion. Although he did not sign the British North America Act, which created Canada, he played a significant role in shaping the provincial governance that followed. Mowat served as Ontario's Premier from 1872 to 1896, contributing to the development of Canadian federalism. His influence continued to be felt in the years following Confederation, as he helped to define the roles of provincial and federal governments.
