It’s often said that small businesses are the backbone of their communities, and a new report shows that the numbers back up that claim.

The Canadian Chamber’s Business Data Lab recently published Scaling Success: Enabling Small Businesses to Grow. Among its findings are that nearly 70% of private-sector jobs are created by small businesses. The report also shows that businesses projecting high growth are typically between five and 19 employees, are owned by immigrants or visible minorities and have been operating between three and 10 years.

In order to grow, the biggest challenges facing businesses are access to financing and technology, as well as a supportive policy environment that provides opportunities to export.
