After digging through 1000s of cards etc, I finally came across the cancel I wanted to show in here.
The Sault Ship Canal post office was located in the Algoma District and opened originally as a Summer office only. It opened on May 31, 1909 and on March 1, 1910. it was allocated as a 'permanent' office.
The cancellation on this card may beone of the EKU of this hammer, a "Split-Ring" because the date on this card is July 18, 1909, only 46 days after it originally opened. The second scan shows a close-up of the cancellation.
I sure love all of this postal history.
