Technology and professional firms, by count
Markham counted 338,503 people in 2021 and 16,411 businesses with employees in Statistics Canada's latest count. Its biggest sector by far is professional, scientific and technical services, 2,981 businesses, a group that takes in software design, engineering and consulting as well as the traditional professions.
Growing teams are where the accounting changes. A company hiring its first employees takes on source deductions and T4 slips, and once an eligible employer's Ontario payroll passes $1,000,000, the Employer Health Tax as well. Meanwhile the owners are deciding how much to take as salary and how much to leave in the company. HBT works on Markham files remotely from Calgary.

When should a growing Markham company set up payroll?
Before the first pay date. A business needs a CRA payroll account to deduct and remit income tax, CPP and EI for its first employee, and remittances then fall due on a schedule set by the size of the payroll.
