Sir, I am doing tax return for both countries now and past 2 years. Cerboros Reborn's number may not be right, but his concept is right. Canada just detuct 15%, the lowest percentage, but US reduce from the high income percentage. For example, Canada, child tax dectuction is 2000X15%=300, but in US, the case is your income $ - 3400. That's totally diferent.
