Lesser Included Offences

This page was last substantively updated or reviewed January 2019. (Rev. # 95296)

General Principles

A judge must consider, where the evidence does not make out a particular charged offence, whether the accepted evidence makes out an "included" offence. That is, a secondary offence which underlies the actual charge.

A lesser included offence must be "embraced" by the primary offence.[1]

This authority comes from s. 662(1):

Offence charged, part only proved

662 (1) A count in an indictment is divisible and where the commission of the offence charged, as described in the enactment creating it or as charged in the count, includes the commission of another offence, whether punishable by indictment or on summary conviction, the accused may be convicted

(a) of an offence so included that is proved, notwithstanding that the whole offence that is charged is not proved; or
(b) of an attempt to commit an offence so included.

Note up: 662(1)

There are three instances where an offence will be "included" within another offence:[2]

  1. offence included by statute, e.g., those offences specified in s.662(2) to (6), and attempt provided for in s.660;
  2. the offence’s elements are embraced in the offence charged as described in the enactment creating it, e.g., common assault in a charge of sexual assault; or
  3. the offence’s elements are embraced in the offence charged as described in the information or indictment. That is to say, the offences which become included by the addition of apt words of description in the principle charge.


Fair Notice required

For an offence to be included, the accused must have "fair notice" that the included offence exists by the definition of the primary offence.[3]

Test From Implied Inclusion

The primary test for whether an offence is “included” in another offence is "if its elements are embraced in the offence charged (as described in the enactment creating it or as charged in the count) or if it is expressly stated to be an included offence in the Criminal Code itself. The test is strict. It must “necessarily” be included..."[4]

The two considerations are that 1) the "main offence contains the essential elements of the offence to be included", and 2) "the description of the offence is sufficient to alert the accused to all of the included offences that may apply."[5] This section element requires that "the offence charged, either as described in the enactment creating the offence or as charged in the count, must be sufficient to inform the accused of the included offences which he must meet."[6]

All essential elements to the included offence must be found within the primary offence.[7]

Jury Instructions

The trial judge must instruct on the availability of a lesser included offence where there is an air of reality to it.[8] Conversely, offences that are not included offences cannot be left with a jury.[9]
