A growing city of small firms
Oshawa grew by 10% between 2016 and 2021, to 175,383 people. Statistics Canada's latest count found 3,926 businesses with employees, and the largest group, 632, was professional, scientific and technical services, ahead of retail (559) and health care (434).
Many of those firms began as one person working under their own name, and sooner or later the owner asks whether to incorporate. Ontario lowered its small business rate from 3.2% to 2.2% effective July 1, 2026, and a tax year that straddles that date blends the two rates by the number of days each applied. For a year that falls wholly after it, a corporation pays 11.2% combined on the first $500,000 of active business income. That saving holds only for profit left in the company. HBT works from Calgary and handles Oshawa files remotely.

When should an Oshawa sole proprietor incorporate?
Usually once the business earns more than the owner needs to live on. Profit kept in an Ontario corporation is taxed at 11.2% combined on the first $500,000 of active business income for the days from July 1, 2026 (12.2% for earlier days), and taxed again personally only when it is paid out. If every dollar is needed at home, a corporation mostly adds cost: a second return, separate books and legal fees.
