These are not errors. Reverse engineer the math: Federal difference is $150 - $142.11 = $7.89, times 26 periods = $205.14, divide by 15% credit rate = $1,368 which is the Canada employment amount. Ontario difference is $62.04 - $50.50 = $11.54, times 26 periods = $300 which is the Ontario health premium on income between $25k and $36k. The withholding rates are based on tables set out in regulations. There is no need to second guess the government calculations. More on reddit.com
