Purchasing a home involves a lot of paperwork, most of which are contractual documents that will legally bind you to the numerous terms and conditions. For this reason it is important to have a good lawyer acting for you. Someone to protect your rights and interests.
The legal process varies from province to province within Canada. Specifically, you will need to consult with your chosen legal professional and he/she will explain the process and the steps that need to be completed before you get the keys to your new home.
Your lawyer will prepare a "Statement of Adjustments" outlining all the financial aspects of your sale.
