There are 134 locations in Canada that have affiliate library status with FamilySearch. That’s according to this tabulation at the FamilySearch wiki. Ontario has 86, Quebec 19, Alberta 12, British Columbia, Nova Scotia 5 and Prince Edward Island 1.
Don’t take the listing as gospel. The Toronto Public Library is listed once although there’s access at all branches AFAIK., whereas 6 locations are listed in Burlington.
There’s no affiliate library access at all in Ottawa!!!!!
The closest would appear to be Biblotheque et archives nationales Du Quebec- BAnQ Gatineau at 855, boulevard de la Gappe.
There’s also Eastern Ontario access via the Mississippi Mills Public Library – Almonte Branch at 155 High Street, Almonte; Mississippi Mills Public Library – Pakenham Branch, 128 MacFarlane Street, Pakenham; Upper Ottawa Valley Genealogical Group at 222 Dickson St., Pembroke; Kingston Frontenac Public Library, 130 Johnson Street, Kingston; and Madawaska Valley Public Library at 19474 Opeongo Line, Barry’s Bay.
According to a recent blog post on Irish Genealogy News:
“The difference between accessing FamilySearch.org from your personal device and searching via an Affiliate Library terminal is that you can access a portion of FamilySearch’s digitised microfilms that researchers cannot view via regular Internet access.
The FamilySearch wiki suggests the Affiliate computer will give you up to an additional 400 million records. So, if your regular computer is showing the camera icon with a key symbol above it alongside the name of the collection you want to search, you probably need to visit an affiliate library. Check with the library before travelling, though, as it’s possible access to that particular collection may be available only at a Family History Center (FHC).”
