No, it is not smart. An attorney knows law, however we have a saying in real estate: "We don't practice law, and lawyers don't practice real estate". You are doing yourself a disservice by not taking advantage of a Realtor's expertise of the local market.
I assume that you know that when a Realtor represents you in the purchase of a home that they "work for free", meaning the seller pays the costs of selling commission. So I do not know why you would not want to use one.
One more thing: overall sellers that sell "on their own" sell for an average of 16% less than sellers that use Realtors (NAR 2006 Seller survey). There is a big difference between knowing the legal aspects of real estate and the value of real property.
Best of luck to you.
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.
