I think there is not much of a defence because the picture shows the car running the red.
It may be a defence if the person driving did not have permission.
The law here is the same as it is with respect to photo radar.
The owner is responsible.
Thank you. One more question: is it possible to require the prosecution to prove that the red light camera was in good technical order (i.e. no doubt that the picture does not present a "false positive")?
Yes you can but it's hard to see how a false positive would work logically.
I think, honestly, your best move, is to make a deal with the Crown to plead guilt to a lesser offence.
It's very likely the Crown will agree because this avoids a trial.
