Bill C‑270 amends section 34 of the Criminal Code (the defence of person) by adding three new subsections. It (1) explicitly allows a person lawfully in a dwelling-house to use force, “including lethal force,” that they deem reasonably necessary against someone who has entered without being entitled by law; (2) creates a rebuttable presumption that such an entrant had intent to use force; and (3) creates a rebuttable presumption that the statutory conditions for the self‑defence provision are met when force is used against such an entrant.
This package of presumptions materially changes the evidentiary posture in self‑defence cases arising inside homes. By design it makes it easier for an accused to invoke s.34: certain facts about the entrant will count as proof unless contradicted, putting pressure on the Crown to disprove those presumptions.
That shift raises immediate questions about scope (how “dwelling‑house” and “entitled by law” are defined), interaction with existing reasonableness standards, and potential consequences for prosecutions, civil liability and encounters involving police, social workers, intimate partners or cohabitants.
At a Glance
What It Does
The bill inserts three new subsections into Criminal Code s.34: a provision authorizing force ‘including lethal force’ against an entrant not entitled by law to be in a dwelling-house; a rebuttable presumption that an unlawful entrant intended to use force; and a rebuttable presumption that the statutory conditions for self‑defence are satisfied when such force is used.
Who It Affects
Directly affected parties include people charged with assault or homicide arising from force used in a dwelling-house, Crown prosecutors, defence counsel, and judges who must apply the new presumptions. It also affects entrants (suspected intruders), police and other authorized entrants whose legal entitlement to enter may be contested in court.
Why It Matters
The bill shifts evidentiary burdens toward rebutting presumptions in favour of the defender, which can make convictions harder to obtain and change trial strategies. It may also change behavior at the margins — from when police knock at a door to how disputes between cohabitants are litigated — because the law grants broader presumptive protection to those who use force against certain entrants.

What This Bill Actually Does
Section 34 of the Criminal Code currently allows a person to use force to defend themselves or another if the force is reasonable in the circumstances. Bill C‑270 leaves that statutory framework intact but adds three targeted presumptions that come into play when an unlawful entrant is involved.
First, it says that the defensive act may include lethal force that the resident “deems reasonably necessary” against someone who has entered their dwelling-house without lawful entitlement; the insertion foregrounds and explicitly authorizes lethal force where the factual trigger (an unlawful entry) exists.
Second, the bill declares that an entrant’s being knowingly in the dwelling without lawful entitlement is proof, “in the absence of evidence to the contrary,” that the entrant entered with intent to use force against a person lawfully present. That language creates a rebuttable presumption about the entrant’s intent: if the fact of unlawful entry is proved, the court will accept intent to use force unless contrary evidence is produced.Third, the bill goes further and says that the conditions required by subsection (1) — the statutory elements that make self‑defence lawful — are presumed to be met when the resident uses force against an entrant who is not lawfully entitled to be there.
In short, two related presumptions now work together: one about the intruder’s intent and a second about the defender’s satisfaction of the statutory defence conditions. Both are rebuttable, but they alter which party must introduce evidence on certain facts.The text leaves several consequential questions for courts and practitioners.
It does not define “dwelling‑house” beyond the ordinary meaning, does not enumerate who is “entitled by law” (police with warrants, landlords, caretakers, cohabitants with keys), and does not change the ultimate legal standard of reasonableness that judges and juries must apply. Those gaps will be resolved in litigation and by judicial interpretation, but the immediate practical effect is to change trial dynamics, investigative priorities, and plea negotiations in cases that arise from confrontations inside homes.
The Five Things You Need to Know
The bill’s short title is the “Stand on Guard Act.”, It inserts s.34(1.1) to state that the act constituting an offence may involve force, “including lethal force,” that the defender deems reasonably necessary against someone who has entered a dwelling-house without being entitled by law.
It creates s.34(2.1), a rebuttable presumption that an unlawful entrant’s presence is proof they entered with intent to use force, unless evidence to the contrary is produced.
It creates s.34(2.2), a rebuttable presumption that the statutory conditions for self‑defence under s.34(1) are met when force is used against an entrant who is not lawfully entitled to be in the dwelling-house.
The bill does not define key terms (for example, “dwelling‑house” or who is “entitled by law”), nor does it add any procedural steps (such as reporting requirements or safe‑retreat duties) before force may be used.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Stand on Guard Act
Section 1 supplies the bill’s short title. It signals legislative intent to frame the amendments around protection of occupants in their homes but carries no substantive legal effect beyond naming the Act.
Explicit authorization of force in response to unlawful entry
This new subsection declares that the act constituting the offence under s.34(1) may involve force, “including lethal force,” deemed reasonably necessary by the person lawfully present when someone who is not entitled by law has entered a dwelling-house. Practically, it foregrounds lethal force as within the scope of potentially justified responses to unlawful entry, while continuing to anchor justification in a reasonableness assessment — though the provision’s wording emphasizes the defender’s assessment of necessity as a factual piece of the analysis.
Rebuttable presumption that an unlawful entrant intended to use force
Subsection (2.1) says that the fact of knowing, unlawful entry is proof, absent contrary evidence, that the entrant intended to use force against a person lawfully present. That creates an evidentiary presumption about the intruder’s state of mind: once unlawful entry is established, the court will presume hostile intent unless the Crown or complainant introduces evidence that undermines that inference. The mechanism shifts the burden of producing contrary evidence and thus changes how trials will structure witness examination and documentary proof about the entrant’s purpose.
Rebuttable presumption that s.34’s conditions are satisfied
Subsection (2.2) presumes that the statutory conditions for the s.34 defence are met if a resident uses force against a person who entered without lawful entitlement. This is broader than the intent presumption: it operates on the question of whether the defender’s conduct falls within s.34, relieving the accused of having to establish those elements initially. The Crown must therefore marshal evidence to rebut that presumption, altering the allocation of evidentiary burdens at trial.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- People charged with assault or homicide arising from force used against an unlawful entrant — the presumptions narrow the factual disputes they must overcome and can make self‑defence easier to establish in court.
- Defence counsel — the presumptions provide clearer, trial‑level arguments to place the burden of production on the Crown and to frame reasonable‑force narratives for juries or judges.
- Owners and occupants of private dwellings who use force in response to unlawful entry — the law makes it more likely their conduct will be treated as justified at trial, reducing immediate arrest-to-conviction risk.
Who Bears the Cost
- Crown prosecutors and police investigations — prosecutors will face an evidentiary presumption to rebut, requiring additional investigative effort to prove lawful entry or to show the presumption is displaced, and police may need to gather more contemporaneous evidence about why a person entered.
- People who enter dwellings with a lawful but contested justification (e.g., family members, cohabitants, social workers, utility workers, or visitors without clear paperwork) — the new text can expose them to a presumption of hostile intent that they must disprove in court.
- Victims of domestic disputes and cohabitants — the provision does not distinguish between a stranger intruder and a household member whose presence may be lawful or contested, creating a risk that the presumption will be used in intra‑household violence to justify force.
Key Issues
The Core Tension
The central dilemma is between strengthening occupants’ ability to defend themselves in their homes by creating presumptions that favor defenders, and the risk that those same presumptions will lower accountability for excessive or lethal force, particularly in ambiguous entry situations (cohabitants, mistaken entrants, or lawful but disputed entries). The bill protects one set of legitimate interests — home security and self‑defence — while making it harder to hold defenders to account where circumstances are unclear.
The bill uses the phrase “in the absence of evidence to the contrary,” which creates rebuttable presumptions rather than conclusive findings. That distinction matters: courts will need to decide whether Parliament intended an evidential presumption (shifting the burden of production) or a legal presumption (shifting persuasive burden).
That line determines how easily a jury or judge can return a guilty verdict when the facts of entry are ambiguous. The statute is silent on standards of proof for disproving the presumptions, which will invite litigation about whether the Crown must negate a reasonable doubt or merely introduce contrary evidence.
Key definitional gaps will drive litigation. Neither “dwelling‑house” nor “entitled by law” is defined; their interpretation will decide whether police with warrants, caretakers, landlords, cohabitants with keys, or emergency responders fall inside or outside the statutory trigger.
The bill also does not address scenarios common in criminal practice: forced re‑entry by an estranged partner with keys, common‑area entries in multi‑unit buildings, or entries by someone who genuinely sought help. Finally, by explicitly authorizing “including lethal force,” the text invites constitutional and public‑policy scrutiny about whether the change encourages disproportionate use of force and how it interfaces with Charter protections and proportionality doctrines.
Operationally, the presumptions will change investigative priorities and courtroom tactics: prosecutors must document entry justifications early; defence counsel can lean on statutory presumptions at bail hearings and in plea talks; juries will receive new doctrinal language to weigh. Those shifts are intentional, but they also risk unintended consequences — from increased lethal responses to contested entries to complexity in cases involving domestic relationships — that the short text does not resolve.
