 Library Express Depot - Glen Walter

The SDG County Library recently launched a new 'Library Express' service depot to members who live in the Township of South Glengarry. This alternative service is available due to a partnership established with owners of the OLCO Gasoline Service Station, 18267 County Road 2 in Glen Walter.

 With a SDG County Library membership card, Library members can request books, DVDs and audiobooks online and have requested items delivered each week to the OLCO station. When finished, borrowed items are then returned to the OLCO station and may either be handed in to the person at the store counter or dropped into the Library's book return box. 

More information can be found at or by contacting the Library Administration Office at 613-936-8777.
