Thomas David Morrison, born in Quebec City in 1796, was a prominent physician and political figure in Upper Canada. His early career saw him serving as a clerk in the medical department of the British Army during the War of 1812, which laid the groundwork for his future in medicine.
After studying medicine in the United States, Morrison returned to York in 1824, where he established himself as a doctor. He played a crucial role in public health, treating patients during the cholera outbreaks of 1832 and 1834 and co-founding the York Dispensary. His commitment to the community extended to his political career, as he was elected to the 12th Parliament of Upper Canada in 1834, representing the third riding of York County as part of the reform movement.
In addition to his parliamentary duties, Morrison served as an alderman on the Toronto City Council and was elected mayor of Toronto in 1836. A staunch advocate for political reform, he actively participated in discussions aimed at fostering change, although he opposed armed rebellion. Despite his non-participation in the Upper Canada Rebellion, he was arrested and charged with treason but was acquitted at trial.
Fearing further repercussions, Morrison fled to the United States, where he continued his medical practice. Following the amnesty granted in 1843, he returned to Toronto, resuming his medical career and contributing to various medical boards until his death from palsy on March 19, 1856.
