I believe (could be wrong) the author of model3tracker.info is a Canadian. If so, it's possible that website was better known in the Canadian community than elsewhere.
Another data point: Repercusión Mundial de TESLA: Análisis Palabra Clave Google did an analysis on google interest for "tesla model 3" and estimated 36k - 37k Canadian reservation holders based on their results, which is somewhere around 7% of the reservations.
