I think that is what happened there! If we look at the riding of Grand Falls, in the first referendum on June 3, 1948, the number of registered voters was 11,458, but the number of voters on June 3, 1948 was 12,580, which gives us a participation rate of 109.79 per cent, which is quite good!
Si on prend, dans la circonscription de Grand Falls, premier référendum 3 juin 1948, dans Grand Falls, 11 458 inscrits, nombre de votants le 3 juin 1948, 12 580; participation de 109,79 p. 100. C'est quand même bien.
