Summary From 1968 to 1970, the Canadian pendulum apparatus of the Earth Physics Branch (formerly Dominion Observatory) was used to establish a network of gravity stations within Canada to provide scale control for the Canadian gravimeter net. The pendulum network, adjusted by the method of least squares, has a standard deviation of 0.12 mgal. Agreement with Faller's absolute apparatus to ‐23 ppm in scale is noted.
