Shapovalov needed just an hour and 13 minutes to beat Eero Vasa 7-6 (7-2) 6-2, backing up his win against Argentine Francisco Cerundolo on Tuesday.
The Canadian served five aces to his opponents' three, producing three love games in the final set to get his nation off to a flying start.
Auger-Aliassime followed up Shapovalov's with another straight sets win, this time over Otto Virtanen, emerging a 6-2 6-3 victor.
The world number 21 was dominant on serve throughout his 73-minute triumph, saving all three break points he faced and winning 86% of his first-serve points.
Auger-Aliassime and Shapovalov then prevailed in the doubles against Harri Heliovaara and Virtanen in another straight sets win, putting them top of Group D.
