William Warren Baldwin (April 25, 1775 – January 8, 1844) was a doctor, businessman, lawyer, judge, architect and reform politician in Upper Canada. He, and his son Robert Baldwin, are recognized for having introduced the concept of "responsible government", the principle of cabinet rule on which Canadian democracy is based.
William Warren Baldwin was born in County Cork, Ireland in 1775 of Robert Baldwin Sr. William graduated from the medical school at the University of Edinburgh in 1797. Faced with the prospect of the uprising of the Society of United Irishmen in 1798, he came to Upper Canada with his father and family, arriving in July 1799. The family moved to Durham County, where he became a lieutenant-colonel in the Durham militia and a justice of the peace in 1800. William found few patients in Durham, so he moved to the town of York (Toronto) and took up other occupations. In 1803, he was admitted to the bar and, in 1809, he became a district court judge. He served several terms as Treasurer of the Law Society of Upper Canada
William married Phœbe Willcocks, daughter of William Willcocks, in 1803. Phœbe and her unmarried sister inherited the estate of their father in 1813, and their cousin Elizabeth Russell in 1822. William inherited his father Robert Baldwin Sr's 200 acre estate in 1817. With this wealth they built an estate in 1818 on the future site of Spadina House and laid out the grand avenue, Spadina, that was to link it to the city. The house burned down in 1835 and was rebuilt on the same foundations. The current building was built on the original foundations.
In 1820, he was elected to the 8th Parliament of Upper Canada representing York & Simcoe. In 1829-30 he represented Norfolk County in the 10th Parliament. His record shows he was no foe of aristocracy, and should be considered a whig constitutionalist. Baldwin's status as gentleman added legitimacy to the reform policies on responsible government that he supported. When he was not re-elected in 1831, he bitterly left politics and focused on other causes such as the response to the 1832 Cholera epidemic, the Mechanics Institute and the House of Refuge and Industry.
In 1836, he became a member of the Constitutional Reform Society of Upper Canada. Lieutenant Governor Sir Francis Bond Head removed him from his appointments as judge. However, Baldwin, although he supported reform, did not endorse the Upper Canada Rebellion, preferring to work through lawful means.

Having spoken directly with Lord Durham in 1838, and seeing that Durham had incorporated the call for "responsible government" in his official report, Baldwin was emboldened to resume direct political participation once more. He and 222 inhabitants of the Home district petitioned Sheriff William Jarvis to call a public meeting to discuss Durham’s recommendation on responsible government in August 1839. Jarvis, however, was swayed by “the influential part of the inhabitants” and refused the reformers. The petitioners decided to call a meeting of the “friends of Responsible Government” for the 15th of October outside the city. When Dr Baldwin called the meeting to order, Jarvis led an Orange Tory mob, which tore a fence apart, and began beating the defenseless crowd. Jarvis led a charge on the wagon on which Baldwin and Francis Hincks were perched, shouting “Down with them! Down with them!” The meeting broke up, but not before a nineteen-year-old member of the Children of Peace, David Leppard, was struck in the temple with a rock with such force that he was knocked from his wagon; he was to die soon after. The death - which was never punished - formed an alliance between the Baldwin family and the Children of Peace.
When Robert Baldwin gave up his seat in the riding of 4th York to take a seat in Hastings, the Children of Peace began a movement to draft Dr. Baldwin to accept the reform nomination to replace him. Dr Baldwin, however, was reticent about accepting. The violence of the Yonge Street Durham meeting had led to strenuous objections from his wife who was “quite terrified” at the thought of his re-entering politics. He ultimately accepted only when Robert quieted his mother’s fears in early August. He quickly abandoned the plan when Robert suggested that Louis LaFontaine run in his stead.
In late 1843, Sir Charles Metcalfe, the Governor General, appointed Baldwin to the Legislative Council of the United Canadas. It was an honour he enjoyed for only a few weeks. He died at Toronto January 8, 1844, aged 69
