General Principles

Certain offences in the Criminal Code require not only that the offender do a prohibited act along with the requisite mens rea, but also that the act caused a particular result. Criminal responsibility for causation must be established in fact and in law.[1] This makes a distinction between the physical, biological, or medical cause a particular result and the legal boundary that would attribute responsibility to the accused for the result.

The standard to prove causation is the same as between all homicide offences, including murder, manslaughter, operation of a motor vehicle causing death.[2] Likewise, the standard applies equally to offences involving bodily harm.

The criminal standard of causation in criminal matters is that the "accused's conduct be at least a contributing cause of the [result], outside the de minimis range"[3]

Criminal law does not include any issues of contributory negligence nor does it apportion responsibility for harm caused outside of sentencing.[4]

The inference of foreseeability can be rebutted with evidence of intoxication.[5]
