Why not call the Land Registry Office or Land Title Office or whatever they call it in TO and ask? I doubt they office a free abstract service, but you should be able to get a copy of the Certificate of Title (or whatever they call it there) at modest cost.
Also, rather than lawyers, I would expect there to be registry services out there that do cost-effective title searches. In BC, we have West Coast Title Search and others. The LRO should be able to point you to some, if you cannot pay the registry directly for the service. I do not know about now, but it used to be you could show up at the Vancouver LTO at 777 Hornby St., pay $1 for a "search ticket" and get a copy of a title to any land registered in Vancouver, which includes most of the lower mainland.
