A search warrant is a court order authorizing police to search a specific place for specific items. Understanding, in general terms, how warrants work can help someone respond calmly if police arrive at their home or business with one. This guide is general information only and does not replace legal advice about a specific warrant or search.
What Is a Search Warrant?
A search warrant is a legal document, issued by a justice of the peace or judge, that authorizes police to search a specific place for specific items connected to a suspected offence. Warrants exist to ensure that an independent judicial official reviews the basis for a search before it happens, rather than leaving that decision entirely to the discretion of investigating officers.
Because a warrant involves independent judicial oversight in advance, a search conducted under a valid warrant is generally considered more likely to be reasonable than a warrantless search, though a warrant is not an automatic guarantee that every aspect of how it was obtained or executed complied with the law.
Warrants exist for a range of purposes beyond typical criminal investigations, including searches connected to specific regulatory schemes. This page focuses generally on warrants connected to criminal investigations, since that is the context most relevant to the rest of this website.
How Police Obtain a Warrant
To obtain a warrant, police generally need to satisfy a justice of the peace or judge that there are reasonable grounds to believe an offence has been committed and that evidence connected to that offence will be found in the specific place to be searched. This is generally done through a sworn document, often called an information to obtain, which sets out the evidence and reasoning supporting the request.
The justice of the peace or judge reviewing this request acts as a check on police, deciding whether the information provided meets the legal threshold before authorizing the search. This process generally happens before the search, without the knowledge of the person whose property will be searched.
Because this process happens without the affected person's participation, it relies heavily on the accuracy and completeness of what police present to the justice of the peace or judge. If the information provided later turns out to have been misleading, incomplete, or based on unreliable sources, that can become a significant issue in a later legal challenge to the resulting search.
What a Warrant Must Generally Specify
A valid warrant generally specifies the location to be searched, the items being sought, and the offence connected to the search. This specificity is meant to limit the scope of a search to what was actually authorized, rather than permitting a general, open-ended search of a property.
This specificity requirement matters in practice. If police search areas or seize items well outside what a warrant describes, that mismatch can become an important detail for a lawyer reviewing the search later. Keeping a careful, honest account of exactly what was searched and seized, compared to what you understood the warrant to authorize, can be genuinely useful information to bring to that conversation.
Who Issues a Warrant
In Ontario, search warrants are generally issued by a justice of the peace or a judge, depending on the type of warrant and the nature of the investigation. This judicial officer is meant to act independently of the police requesting the warrant, providing a neutral check on the decision to authorize a search.
Telewarrants
In some circumstances, police can apply for a warrant remotely, sometimes called a telewarrant, such as by telephone or another form of telecommunication, generally where it would be impractical to appear in person before a justice of the peace. This process is generally meant to be used in specific circumstances that justify the alternative to an in-person application, rather than as a routine substitute.
A telewarrant is still generally subject to the same underlying legal requirements as an in-person warrant application, including a sworn account of the grounds supporting the request. If a warrant was obtained this way, that fact alone does not make it invalid, though the specific circumstances of how it was obtained can be relevant to a later legal review.
How Long a Warrant Is Valid
A search warrant generally specifies, or is understood to have, a limited period during which it may be executed, rather than remaining valid indefinitely. If a warrant is executed well outside any applicable timeframe, or under circumstances that have materially changed since it was issued, that can potentially become relevant to a legal challenge. A lawyer can review the timing of a specific warrant's execution as part of a broader assessment of the search.
Executing a Warrant: What to Expect
When police execute a search warrant, they generally identify themselves, state that they have a warrant, and proceed to search the specified location for the items described in the warrant. The process can vary in scale, from a brief, targeted search to a more extensive search involving multiple officers and specialized units, depending on the nature of the investigation.
It is generally advisable to remain calm and not interfere with the execution of a warrant, even if you believe there is a problem with it. Raising concerns about a warrant's validity is generally something to pursue afterward, through a lawyer, rather than during the search itself.
Police executing a warrant will generally document what was searched and what, if anything, was seized, often providing a written inventory before leaving. Keeping a copy of this documentation, along with your own notes about how the search unfolded, can be valuable if you later speak with a lawyer about the search.
Interfering with the execution of a warrant, even one you believe may be flawed, can create separate legal problems. The appropriate way to challenge a warrant is through the legal process afterward, not through physical resistance at the scene.
Your Rights When a Warrant Is Executed
Even when police are executing a valid warrant, certain general rights and protections continue to apply, including the right to remain silent about matters beyond what is required, and, if you are detained or arrested during the execution of a warrant, the right to speak with a lawyer. Our guides to the right to remain silent and the right to a lawyer explain these protections in more detail.
Being present for a warrant search does not require you to answer questions from police about the investigation, even while the search is happening around you. You can generally comply with reasonable safety instructions, such as staying in a particular room, while still declining to answer investigative questions until you have spoken with a lawyer.
Can You Ask to See the Warrant?
Yes, it is generally reasonable to ask to see a copy of the warrant when police arrive to execute it. Reviewing it, even briefly, can help confirm basic details such as the address and general scope of the search. If police decline to show the warrant immediately, it is generally best to avoid arguing extensively about it in the moment and instead raise this concern with a lawyer afterward.
What If No One Is Home?
Police executing a warrant do not necessarily need the occupant to be present. Depending on the specific circumstances and the terms of the warrant, police may enter a property to execute a valid warrant even if no one answers the door, generally leaving documentation of the search and any items seized. If this happens, contacting a lawyer as soon as possible to understand the situation and any next steps is generally advisable.
Returning home to find that a search has already taken place can be a disorienting experience. Reviewing whatever documentation was left behind, taking photographs of the property's condition, and contacting a lawyer promptly are generally reasonable steps to take before making any other decisions about the situation.
Businesses and Warrants
Search warrants can also be executed at businesses, and business owners or employees present at the time generally have many of the same practical considerations as an individual at a home, including remaining calm, not interfering with the search, and asking to see the warrant. Business records and electronic systems can raise additional considerations, particularly around client or customer information not connected to the investigation, which a lawyer can help address if it becomes relevant.
If a warrant is executed at a business, notifying a lawyer as soon as possible, and, where relevant, considering whether other affected parties such as clients need to be informed, are generally important early steps, alongside cooperating with the lawful execution of the warrant itself.
If You Are Not the Target of the Investigation
Sometimes a warrant is executed at a property connected to someone other than the primary target of an investigation, such as a roommate, family member, or landlord. Being present when a warrant is executed does not necessarily mean you are a suspect, but it is still generally wise to understand your own rights during the search, including the right to remain silent about matters beyond what is required and the right to speak with a lawyer if you are detained or arrested.
If you are unsure of your own role or status during a search connected to someone else, it is generally reasonable to ask, calmly, whether you are free to leave or are being detained, similar to the general approach discussed in our guide to rights when detained.
Other Types of Warrants and Orders
Beyond a standard search warrant for a physical location, Canadian law includes other, more specialized types of warrants and orders, such as production orders requiring a third party to produce specific records, and warrants connected to tracking or electronic surveillance. These specialized tools have their own specific legal requirements, which are beyond the scope of this general overview. A lawyer can explain how a specific type of order applies to a particular situation.
Challenging a Warrant
A warrant, and how it was obtained or executed, can potentially be challenged in a criminal case, for example on the basis that the information provided to obtain it did not meet the required legal threshold, or that the search exceeded what the warrant actually authorized. This is a detailed legal process generally pursued by a lawyer as part of a criminal case, involving careful review of the warrant application and the manner in which the search was carried out.
To mount this kind of challenge, a lawyer will generally need to obtain and review the sworn information used to obtain the warrant, comparing what was represented to the justice of the peace or judge against what is now known about the investigation. This process can take time and often requires specific procedural steps to access the underlying warrant materials.
If a challenge to a warrant succeeds, this can potentially affect how evidence obtained during the resulting search is treated in the criminal case, though the specific consequences depend heavily on the nature of the problem found and the overall circumstances of the case.
Frequently Asked Questions
Can I refuse to let police in if they have a warrant?
Generally, no, if the warrant is valid and covers the property in question. It is better to allow the search and raise any concerns about the warrant with a lawyer afterward.
Do police have to show me the warrant before searching?
You can generally ask to see it, and doing so is a reasonable request. If there is a delay in being shown the warrant, raise this with a lawyer afterward.
Can police search areas not mentioned in the warrant?
A warrant generally limits the scope of a lawful search to what it specifies. Searching well beyond that scope can potentially be challenged, and a lawyer can assess the specific facts.
What happens to items police seize during a search?
Seized items are generally held as evidence, and there are legal processes governing how long they can be held and how a person may seek their return, depending on the circumstances.
Can a search warrant be challenged after the fact?
Yes, a lawyer can review how a warrant was obtained and executed and, where appropriate, challenge it as part of a criminal case.
Can police get a warrant by phone instead of in person?
In some circumstances, yes, through a process sometimes called a telewarrant, generally used where an in-person application would be impractical.
What if police search a business I work at but I am not under investigation?
You are generally still expected to cooperate with the lawful execution of the warrant, but your own rights, including the right to remain silent and to speak with a lawyer if detained, still apply.
