Why did John Graves Simcoe choose York as the capital of Upper Canada?

In 1793, Lieutenant Governor John Graves Simcoe selected the site of present-day Toronto to serve as the capital of Upper Canada, subsequently renaming it York.

Simcoe chose this location for several strategic reasons:

• Natural Harbor: The site featured a fine harbor, which was essential for maritime access and security.1
• Strategic Defense and Trade: The location was considered ideal for both military defense and the facilitation of trade.1
• Hinterland Potential: Simcoe recognized the rich potential of the surrounding wilderness hinterland to support the growth and development of the new province.1

Prior to this selection, the provincial parliament had met at Niagara in 1792, but Simcoe sought a more suitable capital to anchor the administration of Upper Canada.1
