1. Determine your budget: Before you start looking at homes, it's important to determine how much you can afford to spend. Take into account your income, expenses, and debts to come up with a realistic budget. This will help you narrow down your search and avoid the disappointment of falling in love with a home that is outside your price range.

2. Research neighbourhoods: Ontario is a large province with a diverse range of neighbourhoods. Research the areas you are interested in to find out about the local amenities, schools, and safety ratings. This will help you find a neighbourhood that suits your lifestyle and needs.

3. Get pre-approved for a mortgage: Getting pre-approved for a mortgage can give you a better idea of how much you can afford to spend and help you move quickly when you find the right property. It also shows sellers that you are serious about buying and can give you an advantage in a competitive market.

4. Work with a reputable real estate agent: A good real estate agent can help you navigate the complex process of buying a home. Look for someone who is experienced, knowledgeable about the local market, has a good reputation and who has experience working with first-time homebuyers. They can help you find properties that meet your criteria, negotiate with sellers, and guide you through the paperwork.

5. Be prepared to negotiate. In today's competitive real estate market, it's important to be prepared to make an offer that is both competitive and attractive to sellers.

6. Don't forget about closing costs: In addition to the purchase price of the home, there are several other expenses to consider, such as legal fees, land transfer fees, and home inspection costs. Make sure you budget for these expenses so you are not caught off guard at closing.
