Cheng challenged a home-surveillance video and screenshot as possibly altered or misdated. The court accepted testimony from the former partner and daughter that the files came from the system’s SIM card and were uploaded unchanged, found the gap explainable, admitted the exhibits, and convicted him.

Rules cited: Canada Evidence Act s.31.1
