Let's calculate payroll deductions for an employee with a gross pay of $2,500 per month.

Deduction	Calculation	Amount
Canada Pension Plan (CPP)	$2,500 × 5.95%	$148.75
Employment Insurance (EI)	$2,500 × 1.66%	$41.50
Ontario Income Tax	Progressive calculation	$325.00
Total Deductions	$148.75 + $41.50 + $325.00	$515.25
