I searched the address on Commercial Drive and there is no cemetery there.
I worked at Riverview Hospital (Essondale) back in the 70's and live very close to it. There is a graveyard there and even though the hospital is closed the graveyard is still maintained. The graves in the cemetery are all marked with plaques and there is someone who is photographing the markers and posting them. Here is a link with links to his blog, etc.

Good luck.
