Unlike John A. Macdonald, Oliver Mowat is quiet, sober and deeply religious. The two work together in Macdonald's Kingston law office for four years, after which time Mowat decamps for Toronto to further his legal career. Eventually, Mowat finds his way into politics, and for almost 24 years is the Liberal premier of Ontario – 18 of of them while Macdonald is Prime Minister of Canada. Mowat often clashed with his former mentor over issues related to federal/provincial sharing of power.
