Arrest warrants and making a lawful arrest

▶ Video coming soon A video version of this lesson is on the way.

Two weeks after the Lakeshore Hardware break-in, Port Ardent detectives connected Kyle Brandt to an earlier break-in at a bicycle shop. By then he had been released, and he did not answer when officers called. Desjardins uses the case to show the other half of arrest powers: the arrest warrant. Where an officer cannot arrest without a warrant, or where the person is not in front of them, the officer swears an information before a justice and asks for a warrant to compel the person's attendance. A warrant transfers the decision from the officer to a judicial officer, and gives every officer who finds the person the authority to arrest them.

Informations, summonses and warrants

Under section 504 of the Criminal Code, anyone who believes on reasonable grounds that a person has committed an indictable offence may lay an information in writing and under oath before a justice. In practice, the informant is usually a police officer. Under section 507, the justice hears the informant's allegations and, where they consider a case for doing so is made out, issues either a summons or a warrant. The justice must issue a summons unless the allegations disclose reasonable grounds to believe that it is necessary in the public interest to issue a warrant. A warrant names or describes the accused, sets out the offence briefly, and orders peace officers to arrest the person forthwith and bring them before a justice. Under section 703 a warrant issued by a judge of a superior court or a provincial court judge can be executed anywhere in Canada; other warrants may need to be endorsed by a justice in the province where they are executed, under section 528.

Warrants are not just for absent suspects. They also allow officers to compel attendance when an accused fails to appear in court, when a person breaches release conditions, and when a court orders a person committed to custody after sentence. The bench warrant issued by a court when an accused fails to appear under section 512 or 597 is one of the most common warrants officers encounter. Desjardins notes that a large share of warrant arrests in Port Ardent are for missed court dates, and that a phone call and a new date often solve the problem without an arrest when the service has a warrant resolution program.

Executing a warrant: confirming identity and validity

The warrant gives the authority, but the officer still has duties. First, they must confirm that the person in front of them is the person named. Mistaken identity on warrants is one of the most common causes of wrongful detentions: two people with the same name and similar dates of birth, an alias, a wrong address in the database. Officers should compare the description, date of birth, photographs and identifying marks, and confirm the warrant is still active with the issuing agency or records unit before relying on it. Section 495(1)(c) allows an arrest on reasonable grounds to believe a warrant is in force, so an officer who acts reasonably on a database entry is protected even if it turns out to have been executed, but a court will not accept an arrest where obvious differences were ignored.

Second, the officer should know what the warrant actually authorizes. A warrant to arrest is not a warrant to search a house, and a warrant from another jurisdiction may need extra steps before it can be executed. Desjardins shows the class a warrant record from Port Ardent's system and walks through each field: the issuing court, the offence, the type of warrant, the date issued, any endorsements, whether it is a Canada-wide warrant, and the instructions for release.

# Checking a person against a warrant record before arrest
warrant = {"name": "Kyle Brandt", "dob": "2002-09-17", "height_cm": 173,
           "marks": {"scar right eyebrow"}, "status": "active"}
person = {"name": "Kyle Brandt", "dob": "2002-09-17", "height_cm": 175,
          "marks": {"scar right eyebrow", "tattoo left wrist"}}
checks = {
    "name matches": warrant["name"] == person["name"],
    "date of birth matches": warrant["dob"] == person["dob"],
    "height within 5 cm": abs(warrant["height_cm"] - person["height_cm"]) <= 5,
    "recorded marks present": warrant["marks"] <= person["marks"],
    "warrant still active": warrant["status"] == "active",
}
for name, ok in checks.items():
    print(f"{name:24} {'yes' if ok else 'NO'}")
print("confirmed:", all(checks.values()))
Output
name matches             yes
date of birth matches    yes
height within 5 cm       yes
recorded marks present   yes
warrant still active     yes
confirmed: True

All five checks pass. The extra tattoo is not a problem, because a warrant record lists marks known when it was created, and people acquire new ones. A different date of birth or a missing scar would be a reason to stop and check further before arresting. Desjardins tells the class that the five minutes spent confirming identity is the best investment an officer can make on a warrant call.

Entering a home to arrest: Feeney warrants

In R. v. Feeney (1997), the Supreme Court held that, except in exigent circumstances, police may not enter a dwelling to make an arrest without prior judicial authorization, even if they have grounds to arrest. Parliament responded with sections 529 to 529.5 of the Criminal Code. A justice may authorize entry into a specified dwelling to arrest a person, either in the arrest warrant itself under section 529, or in a separate warrant under section 529.1 where the person is not named in an arrest warrant but there are grounds to arrest. Under section 529.4, officers must announce their presence and purpose before entering unless the warrant authorizes entry without announcement, or the officer has reasonable grounds to suspect that announcing would expose officers or others to harm or result in the loss of evidence. Section 529.3 allows entry without a warrant in exigent circumstances, defined to include grounds to suspect that entry is needed to prevent imminent bodily harm or death, or grounds to believe evidence relating to an indictable offence is present and entry is needed to prevent its imminent loss or destruction.

The practical effect is that an officer who knows a suspect is at home and has grounds to arrest usually cannot simply walk in. They can ask the person to come out, wait for them to leave, obtain consent to enter, or apply for the right warrant. Desjardins describes a stand-off from his career where officers surrounded a house for four hours while a detective drafted a Feeney warrant; the suspect walked out to buy cigarettes before it was signed and was arrested on the sidewalk without incident.

Eight steps in two rows: 1 plan and approach, 2 identify yourself, 3 tell the person they are arrested, 4 control and handcuff, 5 search incident to arrest, 6 rights and caution, 7 transport and book, 8 notes and report.
The steps of a lawful arrest.

Making the arrest: the practical steps

Desjardins walks the class through the steps of an arrest as they will be taught in the academy, emphasizing the legal duty attached to each. Planning comes first: where possible, officers decide in advance who will speak, who will control the person, where the arrest will happen and what the risks are, including weapons, other people present and escape routes. Officers identify themselves as police unless they are obviously in uniform. They then tell the person clearly that they are under arrest and why. Control and handcuffing follow, using only the force reasonably necessary, which LES-204 covers in depth; handcuffing is not automatic and should be justified by the risk, though most services require it for prisoners being transported.

Telling the person why is a constitutional duty under section 10(a), and under section 29(2) of the Criminal Code an officer arresting with or without a warrant must give notice of the process or warrant, or the reason for the arrest, where it is feasible to do so. Under section 29(1), an officer executing a warrant must have it with them where feasible and produce it when requested. Section 10(b) then requires the officer to inform the person promptly of the right to retain and instruct counsel without delay, including the availability of free duty counsel and legal aid, and to give a reasonable opportunity to exercise it, subject only to concerns for safety, as LES-111 explained. The caution about the right to silence is not a statutory requirement but is given routinely before questioning.

The search incident to arrest follows, which Lesson 7 covers in detail. Transport and booking come next: the person is placed in a cruiser, ideally with a camera recording, and taken to the station or court. Throughout, the officer is responsible for the person's safety. People in custody can be injured, intoxicated, suicidal or ill, and the officer who made the arrest is the first person who can notice. Finally, the officer records every step with times, as Lesson 3 described.

Arrests of youths and vulnerable people

Arrests of young people follow additional rules. Under the Youth Criminal Justice Act, a young person who is arrested must be told of the right to counsel in language appropriate to their age and understanding, and under section 26 a parent must be notified as soon as possible. Section 146 adds strict requirements before a statement from a young person can be admitted, including that the young person be told of the right to consult a lawyer and a parent and to have them present. People with mental health conditions, intellectual disabilities or language barriers may not understand what is happening; the officer's duty to inform and to give rights in a way the person understands applies to them too.

Warrant resolution and voluntary surrender

Not every warrant needs to be executed at the front door at dawn. Many people with outstanding warrants, especially for missed court dates, have simply moved, forgotten or been afraid to call. Port Ardent runs a warrant resolution program with the local court: people can call to arrange a new court date or surrender at a set time, often at the courthouse rather than the police station, with a lawyer present if they wish. Desjardins describes the effect: in the program's first year, several hundred warrants were resolved without a single forced entry or roadside arrest, and the number of people who missed their new court date was lower than among those arrested on the street.

When a person with a serious warrant wants to surrender through a lawyer, officers should arrange it rather than rush to arrest. A planned surrender removes the risk of a confrontation, gives the person a chance to arrange child care and work, and usually produces a calmer interview if the person chooses to speak. Detectives in the Lakeshore case used this approach for the bicycle shop warrant: once Brandt's lawyer called, they agreed on a time, and he walked into the station with her the next morning.

Officers should still verify the warrant on the day, because warrants are sometimes cancelled by a court in the meantime. And they should record the arrangement and the time of the surrender, so that any later question about delay can be answered. Desjardins tells the class that the best measure of an officer's skill with warrants is not how many arrests they make, but how many warrants they resolve safely.

Worked problem

Executing a warrant at a third party's home

Detectives have an arrest warrant for Kyle Brandt for the bicycle shop break-in. A neighbour tells them Brandt is staying at his friend Nolan's apartment. The detectives want to go there and arrest him. What do they need?

Show solution
  1. Recognize that Nolan's apartment is a dwelling, and Brandt is not the occupant, so the arrest warrant alone does not authorize entry.
  2. Options: wait for Brandt to come out; knock and ask Nolan for consent to enter; or apply for an authorization under section 529 or 529.1 to enter that specific dwelling, which requires reasonable grounds to believe Brandt is inside.
  3. If Brandt comes to the door and steps outside, he can be arrested on the warrant in a public place.
  4. If entry is authorized, announce presence and purpose before entering unless the authorization or the circumstances allow otherwise.
  5. Confirm identity and that the warrant is still active before making the arrest, and record each step.

Answer: The detectives need Nolan's consent, a Feeney authorization naming that dwelling, or exigent circumstances; otherwise they should arrest Brandt when he leaves.

Common mistakes

  • MistakeA database hit is all an officer needs to arrest.

    InsteadConfirm identity and that the warrant is still active; ignoring obvious differences can make the arrest unlawful.

  • MistakeAn arrest warrant lets officers enter any home to find the person.

    InsteadEntry into a dwelling needs a Feeney authorization naming it, consent or exigent circumstances.

  • MistakeHandcuffing is required for every arrest.

    InsteadHandcuffing must be justified by risk, though most policies require it for transport.

  • MistakeTelling the person why can wait until the station.

    InsteadSection 10(a) and section 29(2) require prompt notice of the reason where feasible.

Summary and key terms

  • Informations under section 504 lead to a summons or warrant under section 507; summonses are preferred unless a warrant is needed in the public interest.
  • Before executing a warrant, confirm identity and that it is still active.
  • Entry into a dwelling to arrest needs prior authorization (Feeney; sections 529 to 529.5) unless exigent circumstances exist.
  • The arrest steps are planning, identifying, informing, controlling, searching, rights, transport and records.
  • Section 10(a), 10(b) and section 29 set duties to give reasons, rights and the warrant where feasible.
  • Youths and vulnerable people are entitled to rights explained in a way they understand.

Practice problems

Work each problem on paper first, then reveal the answer to check.

  1. When must a justice issue a summons rather than a warrant under section 507?

    Show answer

    Unless there are reasonable grounds to believe a warrant is necessary in the public interest.

  2. What five checks did the code example run before arrest?

    Show answer

    Name, date of birth, height within 5 cm, recorded marks present, and warrant still active.

  3. What did R. v. Feeney decide?

    Show answer

    Police need prior judicial authorization to enter a dwelling to arrest, except in exigent circumstances.

  4. Why confirm a warrant is still active?

    Show answer

    Warrants are executed, recalled or entered in error; arresting on a dead warrant can be an unlawful detention.
