The North London club ended up holding on for a point as Norwich pushed forward in the final minutes.
Arsenal seemed to have wasted a chance to level when Aubameyang’s penalty — awarded for handball by Norwich’s Christoph Zimmermann — was saved by Tim Krul.
The video assistant referee system, however, caught Max Aarons encroaching on the penalty area as the kick was taken.
Cantwell has made a habit of scoring against bigger clubs, with three of his four Premier League goals this season coming against Arsenal, Chelsea and Manchester City.
Elsewhere, Lys Mousset continued his run of good form with his fourth goal in six Premier League games but it wasn’t enough to give Sheffield United the win in a 1-1 draw at Wolverhampton Wanderers.
French forward Mousset needed just two minutes to score from a cross by George Baldock, but Wolves leveled through Matt Doherty in the 64th.
