A new attempt to put digital photos of tombstones online is the Canadian Headstones Photo Project.
The mission (as stated on the webpage) of this project is to capture digital images of headstones of our ancestors. As decades pass -- many stones are becoming harder, if not impossible, to read the inscriptions they originally contained.
By archiving the images, we can help save these important records and also assist researchers using this valuable resource.
This Headstone Photo Project is a privately sponsored, non-profit, educational site. Success of the Project depends completely upon the activities of many volunteers and other individuals who contribute photographs to the archive.
I looked at the Ontario section and there is nothing there yet. But it will come.
