Criminal Inadmissibility to Canada: What It Means and How to Fix It

A past criminal conviction, even a minor one from decades ago, can be enough to stop someone at the Canadian border or derail a permanent residence application already in progress. This is called criminal inadmissibility, and it catches a lot of people by surprise — including applicants who assumed a conviction was “too old” or “too minor” to matter.
This guide explains what criminal inadmissibility means under Canadian law, the situations that commonly trigger it, and the legal options available to overcome it. See IRCC’s official inadmissibility overview for general programme information.
1. What is criminal inadmissibility?
Criminal inadmissibility is a finding, under section 36 of Canada’s Immigration and Refugee Protection Act (IRPA), that a person cannot enter or remain in Canada because of a criminal conviction or an act they committed. It applies whether the conviction happened in Canada or in another country, and it can affect a visitor visa application, a work or study permit, or a permanent residence application already underway.
The finding is not automatic in every sense — an immigration or border officer assesses the conviction against Canadian criminal law to determine whether, and how, it applies. That assessment is exactly where a legal opinion matters most.
2. Common situations that trigger inadmissibility
People are often surprised by which situations can result in inadmissibility. Common examples include:
01
DUI / Impaired Driving
One of the most common reasons US and other foreign nationals are found inadmissible, including cases that happened many years ago.
02
Theft or Fraud
Even relatively minor property offences can be classified as inadmissibility-triggering under Canadian equivalency.
03
Assault
Including domestic incidents that were resolved without jail time in the country where they occurred.
04
Drug-Related Convictions
Possession, cultivation, or distribution offences, depending on jurisdiction and Canadian equivalency.
05
Pending Charges
In some cases, a charge that has not yet resulted in a conviction can still affect admissibility.
Because Canadian officers assess a foreign conviction against the equivalent Canadian offence, two people with what feels like a similar record can end up with different outcomes depending on exactly how the offence is classified.
3. Serious criminality vs. criminality: why the distinction matters
IRPA separates inadmissibility into two categories, and the category determines which remedies are available and how long they take:
Criminality
Generally applies to less serious offences — the Canadian equivalent offence carries a maximum sentence of less than 10 years, or the person was sentenced to less than six months.
Serious Criminality
Applies to offences where the Canadian equivalent carries a maximum sentence of 10 years or more, or where the person was actually sentenced to more than six months.
Serious criminality carries more limited options and, in some cases, no right of appeal. Getting this classification right — and understanding how a foreign conviction translates under Canadian law — is legal analysis specific to your record, not a general answer that applies to everyone.
4. Your options if you are inadmissible
Depending on the type of inadmissibility and how much time has passed, several legal pathways may apply:
01
Temporary Resident Permit (TRP)
A discretionary permit that allows entry or continued stay in Canada for a specific purpose and time period, despite inadmissibility. It does not resolve the inadmissibility permanently.
01
Criminal Rehabilitation
A formal application demonstrating that enough time has passed since the sentence was completed and that the person is unlikely to reoffend. If approved, it permanently resolves the inadmissibility.
01
Deemed Rehabilitation
In some cases, enough time may have passed automatically for a person to no longer be inadmissible, without needing to apply — but only for certain, less serious offences and specific time periods.
01
Legal Opinion Letter
In some border-crossing situations, a lawyer’s opinion letter addressing how the conviction is classified under Canadian law can support entry.
Which option applies — and whether more than one is available — depends entirely on the specific offence, sentence, and time elapsed.
5. Why this is legal work, not consulting work
Most immigration consulting firms are not equipped to handle inadmissibility cases, because the core of the work is legal: translating a foreign conviction into its Canadian criminal law equivalent, arguing classification where it is ambiguous, and building a case for rehabilitation or a permit. When a client’s situation includes a prior conviction, a pure immigration consulting firm typically has to refer the case out — adding delay and a second set of fees at an already stressful moment.
NextArrival Immigration handles both immigration applications and legal services under one roof. Clients with a complex situation, including inadmissibility, do not need to start over with a different provider partway through.
6. What to do next
Step 1
Gather Your Full Record
Charge documents, conviction details, sentencing information, and any documentation of completed sentences or probation.
Step 2
Don't Assume It's Not a Problem
Do not assume an old or minor conviction is automatically not an issue — get it properly assessed.
Step 3
Book a Consultation
Meet with an immigration lawyer to determine your classification and available options.
Step 4
Flag Time-Sensitive Travel
If travel is time-sensitive, raise that immediately — TRP applications and processing times vary significantly by situation. See IRCC’s TRP application guide.

Frequently Asked Questions
What is criminal inadmissibility to Canada?
Criminal inadmissibility is a legal finding under Canada’s Immigration and Refugee Protection Act (IRPA) that a person cannot enter or remain in Canada because of a criminal conviction or act committed in or outside Canada. It can affect visitor visa applications, work and study permits, and permanent residence applications.
Does a DUI make me inadmissible to Canada?
A driving under the influence (DUI) conviction can result in inadmissibility to Canada, including for US citizens who do not otherwise need a visa to enter. The exact classification depends on how the offence is treated under Canadian law and how much time has passed since the conviction and sentence completion.
Can I still visit or immigrate to Canada if I am inadmissible?
In many cases, yes. Depending on your situation, you may be able to apply for a Temporary Resident Permit (TRP) for a specific trip, apply for Criminal Rehabilitation if enough time has passed, or in some cases qualify for Deemed Rehabilitation. Each option has different eligibility requirements and timelines.
What is the difference between a Temporary Resident Permit and Criminal Rehabilitation?
A Temporary Resident Permit (TRP) is a discretionary, temporary authorisation to enter or remain in Canada despite inadmissibility, typically tied to a specific purpose and time period. Criminal Rehabilitation is a permanent resolution — once granted, the conviction generally no longer makes you inadmissible for future travel or applications.
Do I need a lawyer for a criminal inadmissibility application?
These applications require a legal assessment of how a foreign conviction or act translates under Canadian criminal law, which determines the class of inadmissibility and which remedy applies. This assessment is legal analysis, not a form-filling exercise, and is best handled by a licensed immigration lawyer.
