Frederick Walker Baldwin, also known as Casey Baldwin, paternal grandson of Canadian reform leader Robert Baldwin, was a hydrofoil and aviation pioneer and partner of the famous inventor Alexander Graham Bell. He was manager of Graham Bell Laboratories from 1909–32, and represented Victoria in the Nova Scotia Legislature from 1933–37, where he was instrumental in bringing about the creation of Cape Breton Highlands National Park. In 1908, he became the first Canadian and British subject to fly an airplane.

Robert Baldwin was an Upper Canadian lawyer and politician who with his political partner Louis-Hippolyte Lafontaine of Lower Canada, led the first responsible government ministry in the Province of Canada. "Responsible Government" marked the province's democratic self-government, without a revolution, although not without violence. This achievement also included the introduction of municipal government, the introduction of a modern legal system, reforms to the jury system in Upper Canada, and the abolition of imprisonment for debt. Baldwin is also noted for feuding with the Orange Order and other fraternal societies. The Lafontaine-Baldwin government enacted the Rebellion Losses Bill to compensate Lower Canadians for damages suffered during the Lower Canada Rebellion of 1837–1838. The passage of the Bill outraged Anglo-Canadian Tories in Montreal, resulting in the burning of the Parliament Buildings in Montreal in 1849.
