I wouldn't, especially since you're going it alone. In my area, it would only cost $250 - $450 to have an attorney representing you throughout the close and at the closing table. For that amount of money, it would provide you with peace of mind.
And what would you do if some problem occurs along the way to close; the buyer wants to delay the close several weeks for one reason or another or the attorney contacts you and asks a legal question about your property or title. At the very least, you should have you own title agency at close. If all closings are conducted by attorneys in Ontario, then I would recommend having your own legal council.
