What Happens If You Refuse a Breathalyzer Test in Canada?
Last Updated: October 20, 2023

In Canada, refusing a breathalyzer test can have various legal and practical consequences. It is important to understand the implications and potential ramifications before making a decision. This article aims to provide a comprehensive overview of what happens if you refuse a breathalyzer test in Canada.
Understanding the Breathalyzer Test
Before delving into the consequences of refusal, it is crucial to understand the breathalyzer test itself. This test measures the amount of alcohol in a person’s breath and is commonly used by law enforcement officers to determine impairment while driving.
When it comes to breathalyzer tests, the science behind them is fascinating. The test relies on the principle of infrared spectroscopy, which is a technique used to analyze the interaction between matter and electromagnetic radiation. In the case of a breathalyzer test, the matter being analyzed is the alcohol in a person’s breath.
So how does it work? When alcohol is consumed, it is absorbed into the bloodstream and eventually reaches the lungs. As a person exhales, the breathalyzer measures the concentration of alcohol in their breath. This measurement provides an estimate of their blood alcohol content (BAC), which is a crucial factor in determining whether someone is impaired or not.

The breathalyzer test relies on the principle of infrared spectroscopy. When alcohol is consumed, it is absorbed into the bloodstream and eventually reaches the lungs. As a person exhales, the breathalyzer measures the concentration of alcohol in their breath, providing an estimate of their blood alcohol content (BAC).
It’s important to note that breathalyzer tests are not foolproof. There are various factors that can affect the accuracy of the test, such as the individual’s metabolism, the type of alcohol consumed, and even the temperature of the breathalyzer itself. However, despite these potential limitations, breathalyzer tests are still widely used and considered to be an effective tool in determining impairment.
Legal Basis for Breathalyzer Tests in Canada
In Canada, breathalyzer tests are governed by the criminal code. This legislation grants law enforcement officers the authority to request a breath sample from any individual they have reasonable grounds to suspect has operated a vehicle while impaired by alcohol or drugs.
The legal basis for breathalyzer tests in Canada is rooted in the importance of public safety. Impaired driving is a serious offence that puts not only the driver at risk but also other innocent road users. By allowing law enforcement officers to administer breathalyzer tests, the criminal code aims to deter and prevent impaired driving, ultimately making the roads safer for everyone.
It’s worth noting that refusing to comply with a breathalyzer test in Canada can have serious consequences. Under the criminal code, refusing to provide a breath sample is a criminal offence in itself and can result in penalties similar to those for impaired driving. These penalties can include fines, license suspensions, and even imprisonment, depending on the circumstances.
In conclusion, understanding the breathalyzer test and its legal implications is crucial for anyone who finds themselves in a situation where they may be asked to provide a breath sample. By being aware of the science behind the test and the legal basis for its use, individuals can make informed decisions and ensure they are acting in accordance with the law.
The Right to Refuse a Breathalyzer Test
Although law enforcement officers have the power to request a breathalyzer test, individuals also have certain rights when it comes to refusing this test.
When it comes to the right to refuse a breathalyzer test, it is important to understand the circumstances under which you can exercise this right. While it is generally advisable to comply with a breathalyzer test request in Canada, there can be limited circumstances where you are legally entitled to refuse.
One such circumstance is when a police officer lacks the necessary reasonable grounds to request a breathalyzer test. In order for a breathalyzer test to be legally justified, the officer must have reasonable suspicion that the driver has consumed alcohol or drugs. If the officer does not have sufficient grounds to make this request, you have the right to refuse.
Another circumstance where you can refuse a breathalyzer test is if you have a medical condition that prevents you from providing a proper breath sample. Certain medical conditions, such as asthma or other respiratory issues, may make it physically difficult or even dangerous for you to blow into the breathalyzer device. In such cases, it is within your rights to refuse the test.
Potential Consequences of Refusal
However, it is important to note that refusing a breathalyzer test can have severe consequences. Even if you believe you have valid reasons for refusal, it is crucial to weigh these potential outcomes before making a decision.
One of the potential consequences of refusing a breathalyzer test is that it can result in an immediate suspension of your driver’s license. In many jurisdictions, including Canada, there are laws in place that allow authorities to suspend your license for a certain period of time if you refuse to take a breathalyzer test. This can have a significant impact on your ability to drive and can also result in additional fines and penalties.
In addition to the immediate suspension of your license, refusing a breathalyzer test can also have legal implications. In some cases, refusing a breathalyzer test can be seen as evidence of guilt and may be used against you in court. Prosecutors may argue that your refusal to take the test is an indication that you were aware of your impairment and were trying to avoid detection. This can make it more difficult to defend yourself against charges of impaired driving.
Furthermore, refusing a breathalyzer test can also result in increased scrutiny from law enforcement officers. If you refuse a breathalyzer test, it may lead to a more thorough investigation, including the possibility of a blood test or other forms of testing to determine your blood alcohol concentration. This can prolong the legal process and may result in additional charges or penalties.
Therefore, while you do have the right to refuse a breathalyzer test under certain circumstances, it is important to carefully consider the potential consequences before making a decision. Consulting with a legal professional who focuses on impaired driving cases can help you understand your rights and make an informed decision.
Immediate Consequences of Refusing a Breathalyzer Test
When an individual refuses a breathalyzer test in Canada, there are immediate consequences that can significantly impact them.
Arrest and Detention
If you refuse to provide a breath sample, police officers have the authority to arrest and detain you. This can involve being taken to a police station for further testing or processing.
Once you are arrested for refusing a breathalyzer test, you may experience a range of emotions, from fear and confusion to frustration and anger. The realization that you are now in police custody can be overwhelming, as you are suddenly thrust into a situation that you may have never anticipated.
During the process of arrest and detention, you may be placed in a holding cell, where you will have limited freedom and privacy. The atmosphere can be tense, with the presence of other individuals who may have been arrested for various offences. This can create a sense of unease and uncertainty about what lies ahead.
While in detention, you may be required to undergo further testing, such as blood or urine tests, to determine your blood alcohol concentration (BAC). These additional tests can prolong your stay in custody, adding to the stress and discomfort of the situation.
License Suspension
Additionally, refusing a breathalyzer test can lead to an immediate suspension of your driver’s license. This administrative suspension can range from a minimum of 90 days to even longer periods, depending on prior convictions or circumstances.
Having your driver’s license suspended can have a profound impact on your daily life. The loss of mobility and independence can be challenging, as you may have to rely on alternative modes of transportation or the assistance of others to fulfill your daily responsibilities.
Furthermore, the suspension of your driver’s license can affect your employment, especially if your job requires you to drive. You may face difficulties in commuting to work or performing your job duties, which can lead to financial strain and potential job loss.
The consequences of license suspension extend beyond the immediate impact on your personal and professional life. It can also affect your insurance rates, as insurers may view a license suspension as an indication of risky behaviour. This can result in higher premiums or even the cancellation of your insurance policy, making it more challenging to obtain coverage in the future.
In addition to the practical consequences, the emotional toll of having your license suspended should not be overlooked. The frustration, embarrassment, and sense of isolation that can accompany the loss of driving privileges can contribute to feelings of helplessness and despair.
It is important to consider these potential consequences before refusing a breathalyzer test. Understanding the full scope of the immediate impact can help individuals make informed decisions and consider alternative courses of action.
Long-Term Implications of Refusal
Beyond the immediate consequences, refusing a breathalyzer test in Canada can have long-term implications that are essential to consider.
Criminal Charges and Penalties
If you are charged with refusing to provide a breath sample, you may face criminal charges. The potential penalties for this offence can include fines, probation, mandatory alcohol education programs, and even imprisonment in certain cases.
Impact on Driving Record and Insurance
Refusing a breathalyzer test can also have a substantial impact on your driving record and insurance premiums. Depending on the province or territory you reside in, the refusal may go on your driving abstract and can result in increased insurance rates.
Legal Recourse After Refusing a Breathalyzer Test
After choosing to refuse a breathalyzer test, individuals may seek legal recourse to navigate the complex legal system that follows.
Legal Defenses for Refusal
If you have refused a breathalyzer test, it is crucial to consult a lawyer to explore potential legal defences. They can assess the circumstances surrounding your refusal and identify any grounds for challenging the charges.
Navigating the Legal System Post-Refusal
Once you have decided to refuse a breathalyzer test, understanding the legal process and next steps is vital. It is recommended to seek legal representation to guide you through the legal proceedings and ensure your rights are protected.
In conclusion, the decision to refuse a breathalyzer test in Canada can have significant consequences, both immediate and long-term. It is crucial to understand the science behind breathalyzer tests, your rights in relation to refusal, and the potential legal and practical implications. To make an informed decision, seek legal advice and consider the possible repercussions before exercising your right to refusal.
