6:40 a.m., a townhouse near Bovaird Drive. Loud knocking, officers on the porch, a sheet of paper held up to the glass. Your kids are still asleep. This hypothetical is how many people first meet the law of search and seizure, and it leaves them with a long list of panicked questions. Can they do this? Do I have to let them in? Can I call someone? What about my phone?
The short answers are usually: possibly, yes if the warrant is valid, yes though they may limit it briefly, and it depends. The longer answer involves section 8 of the Canadian Charter of Rights and Freedoms, which says that everyone has the right to be secure against unreasonable search or seizure. That one sentence has generated a detailed body of law, and the law often decides whether a case survives.
Please read this as general information rather than legal advice. Whether a particular search was lawful is a fact-specific question for a lawyer who has seen the warrant and the disclosure.
The Basic Rule: Warrants Come First
The Supreme Court of Canada set the foundation in Hunter v. Southam. Where it is feasible, a search should be authorized in advance by a neutral decision-maker, based on sworn evidence of reasonable and probable grounds. A warrantless search is presumed to be unreasonable, and the Crown must then justify it. A search is reasonable if it is authorized by law, the law is reasonable, and the search is carried out in a reasonable way.
Section 8 protects a reasonable expectation of privacy. That protection is strongest in the home, and it also covers personal information and electronic devices. It can sometimes extend to a business office, a storage locker, or a car, though the expectation in a vehicle or a commercial setting is often lower.
How Police Get a Warrant
The general search warrant provision is section 487 of the Criminal Code. An officer swears an Information to Obtain, often called an ITO, in front of a justice. The ITO has to show reasonable grounds to believe that an offence has been committed and that the items sought, such as evidence of that offence, are at the named place. The application is made without notice to you, so you will have no chance to respond in advance. It can also be made remotely by telecommunication.
The warrant must describe the place and the things being sought, and it must be executed by day unless the justice has specifically authorized execution by night. The police may also use other tools, such as production orders for bank or phone company records, tracking warrants, and the warrants under the Controlled Drugs and Substances Act for drug investigations.
Because the ITO is sworn evidence, it is often the document that matters most in any later challenge. Defence counsel will want to read it closely, including any information from a confidential source.
When the Police Are at Your Door
Having a calm plan helps, and a few steps apply in nearly every case.
Ask to see the warrant. Under section 29 of the Criminal Code, an officer must have the warrant with them where feasible and produce it on request. Read the address, date, offence and the list of items. Take a photo if you are allowed to, or ask for a copy.
Do not obstruct. If the warrant appears to be valid, let the search happen. Arguing, blocking a door or hiding things can lead to new charges and might make everything worse. The place to fight the warrant is in court.
Say clearly what you do not agree to. You can say, “I do not consent to any search beyond this warrant.” This matters when officers ask whether they can look somewhere else, such as a detached garage or a phone.
Ask if you are free to leave. Officers may control the scene for safety and to preserve evidence. If you are detained or arrested, you have the right to be told why and to speak with a lawyer immediately. Ask for that right to be honoured.
Stay silent about the investigation. Friendly questions while they search are still questions. “Whose bedroom is this?” and “Do you know what this is?” can establish knowledge and control. Identify yourself as needed, and otherwise wait for a lawyer.
Do not touch your devices to delete anything. Wiping a phone or shredding papers can be a serious crime in its own right. It also gives the Crown an argument it would not otherwise have.
Make notes afterward. Write down who attended, how they got in, how long they stayed, what they said, what was moved or damaged, and what they took. Photograph any damage. Ask for a receipt or a list, and keep whatever they leave with you.
Situations Where Police Can Search Without a Warrant
Warrantless searches are not always unlawful. Some of the common justifications include:
- Search incident to arrest. After a lawful arrest, police may search the person and their immediate surroundings for safety, to secure evidence, or to prevent escape. The search must be truly connected to the arrest.
- Exigent circumstances. Section 487.11 allows a warrantless search if the conditions for a warrant exist but urgent circumstances make getting one impractical. For example, there may be an immediate risk of evidence being destroyed.
- Investigative detention and safety searches. Under R. v. Mann, an officer who lawfully detains someone on reasonable suspicion may carry out a limited pat-down, if there are reasonable grounds to believe that safety is at risk. This is not a general evidence search.
- Plain view. Officers who are lawfully present can seize evidence they come across in plain view, if its nature is immediately apparent.
- Consent. You can agree to a search. For valid consent, you must have the authority to give it, and must know what you are consenting to and that you may refuse. Ontario’s Court of Appeal addressed these requirements in R. v. Wills. Saying no is not an offence, though police may then seek a warrant.
Entry into a home to make an arrest has its own rules. After R. v. Feeney, Parliament enacted provisions under which police normally need a warrant to enter a dwelling to arrest someone, with an exception for urgent situations such as imminent harm or the destruction of evidence.
Phones, Laptops and Your Data
Devices are in a category of their own, because they can reveal so much about us.
In R. v. Vu, the Supreme Court held that general authority to search a place does not automatically include searching computers found there. A warrant must specifically authorize the search of the devices.
In R. v. Fearon, the Court allowed a limited search of a cell phone incident to arrest, but only under strict conditions: the arrest must be lawful, the search must be truly incidental and tailored to a valid purpose, and police must take detailed notes of what they looked at. That exception is narrow. It does not give an officer a licence to browse.
In R. v. Marakah, the Court recognized that a sender may keep a reasonable expectation of privacy in text messages on someone else’s phone, depending on the circumstances. And in R. v. Bykovets, it held that an IP address can attract a reasonable expectation of privacy.
In practical terms, you do not have to give up a passcode because an officer asks, though the law here can be complex and any court order would need specific advice. Never respond by destroying anything. If your device is taken, tell your lawyer what is on it, especially if it contains privileged communications with a lawyer or sensitive business information.
Businesses, Offices and Solicitor-Client Privilege
Small business owners in Brampton’s industrial and commercial areas sometimes find police at their offices, usually looking for records in a fraud, tax or regulatory investigation. Tell staff in advance that if this happens, they should contact you and a lawyer, and not hinder officers or answer questions about the investigation. Identify files that are subject to solicitor-client privilege, because these need to be protected and may require special procedures. Regulators may also have separate inspection powers under other laws, so an inspection and a criminal search do not always follow the same rules.
After the Search: Getting Your Property Back
Police must report what they seized to a justice, and the justice can order it returned or further detained. Section 490 generally limits detention to 180 days from the seizure, unless a charge has been laid or a justice extends the period on notice, and there are further limits on long-term detention. You or your lawyer can apply for the return of items, particularly if they are not needed for the investigation.
If your business depends on a laptop or file server, say so early. It may be possible to negotiate a copy of the data, or a return after imaging. There is no guarantee, but no one will propose this if you do not ask.
Challenging the Warrant in Court
If charges follow, the defence may bring an application alleging a breach of section 8. Such a challenge can take several forms:
- Facial validity. Does the warrant or the ITO, on its face, show enough for a justice to issue it?
- Sub-facial validity. Is the ITO misleading, incomplete, or based on errors? Under R. v. Garofoli, the court looks at whether, after the problem information is removed, there remains enough to support the warrant. Cross-examining the officer who swore it needs permission from the judge.
- Execution. Even a valid warrant can be carried out unreasonably, such as by a violent or unjustified forced entry, or by going beyond its scope.
If there is a breach, the remedy is usually sought under section 24(2) of the Charter. Evidence is excluded if admitting it would bring the administration of justice into disrepute. R. v. Grant sets out three questions: how serious was the police conduct, how much did it affect the accused’s protected interests, and what is society’s interest in having the case decided on its merits?
Exclusion is not automatic, but where drugs or firearms are found through an unlawful search, its effect on the prosecution can be significant. Standing also matters. You generally have to show your own reasonable expectation of privacy in the place or thing searched.
Common Misconceptions
- “They didn’t read me my rights, so the search is illegal.” A right-to-counsel issue and a search issue are separate, although both can matter.
- “The warrant has a typo, so the case is over.” Minor errors do not usually invalidate a warrant.
- “Nothing was found, so it’s over.” The police can still have grounds to pursue the investigation, and items seized may be under examination.
- “I’m not charged, so I don’t need a lawyer.” This is often when good advice does the most, including advice on whether to speak with police at all.
If your home or business has been searched, or you think it might be, get advice promptly from a criminal lawyer. Keep the warrant, your notes and your receipts, and don’t discuss the matter with others. If charges follow, ask for the ITO as part of the disclosure at the Brampton courthouse at 7755 Hurontario St. You can contact our office to set up a time to review your documents. Even in a frightening moment, these rights continue to apply. Paying attention now can help preserve them for later.
