I recently discovered OurOntario.ca website and thought I'd share it with everyone.
The website states, in part:
Explore your story via OurOntario.ca!
Search across hundreds of sites – digital collections of libraries, archives, museums, historical societies, community groups, government agencies, and content organizations – in seconds.
I've been using it to search for my Ontario ancestors and have found some great images that I would never have seen without it.
Try it, you might just like it!
