I happened by on November 21, 2015. This part of Alberta has churches of different denominations scattered all over. It seems this one may no longer be used on a regular basis. There are more nearby.
The CAA/AMA (Canadian Automobile Association/Alberta Motor Association) used to have markers all over pointing to various spots. I do not know if they still do this. Driving along these roads there are lots of them pointing to various churches on sideroads.
