Hey guyht,
First of all, welcome to Canada. The tax you will pay depends on the province to which you are relocating. Depending on the province, you will pay either HST, or PST and GST. For instance, in Ontario, you pay HST at a rate of 13%. It should be easy to google tax rates by province, so that you know exactly what amount of tax you will be paying. At any rate, the taxman is going to get his share. Enjoy your Canadian experience!
