As far as I know, years ago I was the first to find this site and add it to another database online which I am no longer a member of. I'd be interested to see if another member that still lives in this area would confirm the status of this site.
Talava was a religious retreat that belonged to a Toronto based Eastern European church. Ultimately, because of financial difficulties caused by tax policy adjustment, the entire place became abandoned. When I found it, it was an abandonment seekers dream, with at least 5 cottages easily accessible in varying states of decay. As this was years ago, I lost some of the photos of the event that I used to have.
I am attaching some photos I took, which are not of the greatest quality due to my lack of experience in photography at the time. There are also two snips of data concerning the site.
The location is near Alliston (now New Tecumseh), just off the Nottawasaga River and Talsi road. 1.
