This document was obtained from the National Archives of Canada for use on the Pinetree Line web site in August 1998.

There are a few points that are worthy of additional comment as follows:

1 - The document is dated 23 July 1953, obviously at a time when construction for most of the Pinetree Line radar stations was well under way, but also at a time when there was a great deal of uncertainty pertaining to what the "final product" would actually end up being.

2 - M-104 at Wiarton is identified as a low level gap filler, while the other 8 locations are identified as direction centers or surveillance stations. Of interest is that only 2 of the 8 actually ended up as operational Pinetree Line radar stations. (SM-153 at Kamloops, and M-102 at Barrington).
