In this paper, we use postcolonial theories of temporality—specifically the idea of belatedness—to examine how literal forms of lateness inform the so-called Lucky Moose case, wherein Chinese-Canadian grocer David Chen tardily performs a citizen’s arrest in Toronto. Canadian news media outlets, the Chinese-Canadian community, and R v Chen (2010) all contribute to the construction of Chen as an active legal subject, capable of working through the law on his own terms and in his own temporal framework. Consequently, Chen’s belatedness can be understood as part of a larger politics that serves to transform the temporality of citizenship and citizen’s arrest law in Canada.
