These reels are the indexes of the B,M,D's for Ontario and are up to date as per what is available. These reels do not have actual event documents.
The local Family History Centre may have all the up to date index reels. They certainly have some (but not all) of the reels of the actual records to go with the indexes. The Archives of Ontario will have all of them. Always check online before striking out for Toronto.
The benefit the reels we have locally is that you can go through the indexes at your leisure and then either order the pertinent B,M,D reels on inter-library loan, or be prepared when you visit the Archives of Ontario in Toronto or the local LDS FHC.
