Province of Ontario

Ontario is Canada's leading manufacturing province, accounting for 52% of the total national manufacturing shipments in 2004. Long known as a bastion of Canadian manufacturing and financial solvency, Ontario's public debt-to-GDP ratio is projected to be 37.2% in fiscal year 2019–2020, compared to 26% in 2007–2008.

Toronto, the capital of Ontario, is the centre of Canada's financial services and banking industry. Neighbouring cities are home to product distribution, IT centres, and various manufacturing industries.

In 2014, the section of Highway 401 between Toronto and Waterloo became the world's second-largest innovation corridor after California's Silicon Valley, employing nearly 280,000 tech workers from around the world and containing over 60% of Canada's high tech industry.
