Dear Lynn,
Depending on your down payment, you can obtain a mortgage right away. At 35% down, you don't need to produce proof of income. At a down payment of between 5%-20%, the lender wil look at your current work contract and may release funds. It's definitely best to seek the help of a mortgage broker as they will seek out all possible options for you. I'm a long time real estate agent here in Toronto and would be happy to answer any further questions or put you in touch with some great individuals in the business.
