He studied at the University of Toronto, graduating with a Bachelor of Arts in 1883, and Osgoode Hall, being called to the Ontario bar in 1887.

Even though Ford confessed to the crime, Dewart lost the case when the jury decided to acquit.

[1] During his time as leader, the Liberal Party was divided over the question of prohibition and the conflict between the interests of rural and urban voters.

In the subsequent legislature, Dewart criticised the United Farmer government, causing more discontent among rural Ontarians.
