Inadmissibility is the single fastest way to end a Canadian immigration journey. It does not matter how perfect your study permit application is, how strong your Express Entry profile is, or how compelling your job offer is in Abbotsford. If you fall into one of the inadmissibility categories under the Immigration and Refugee Protection Act (IRPA), the officer is legally required to refuse you, defer you, or remove you. The good news is that most inadmissibility issues are forgivable if you understand the legal framework and apply the correct remedy before applying, not after a refusal arrives in your inbox.
This guide walks through the three most common bars Brazilian applicants run into, criminal, medical, and misrepresentation, plus the lesser-known categories, what IRCC actually checks, and the realistic remedies available in 2026. It is written for people who are about to apply, who already have a complication in their past, or who just received a procedural fairness letter and have very little time to respond.
What "inadmissibility" actually means
Inadmissibility is a finding under sections 34 to 42 of IRPA that you are not allowed to enter or remain in Canada. It applies to temporary residents (visitors, students, workers) and permanent residents alike. A finding of inadmissibility does not require a criminal conviction in Canada, an active deportation order, or a court hearing. An IRCC officer can refuse your application based on a foreign police certificate, a medical exam result, or a discrepancy in your declared travel history.
The categories most likely to affect Brazilian applicants are:
- Criminal inadmissibility (s.36)
- Health grounds (s.38)
- Misrepresentation (s.40)
- Financial reasons (s.39)
- Security, human rights violations, and organized criminality (s.34, s.35, s.37)
1. Criminal inadmissibility under IRPA s.36
Criminal inadmissibility is the category most Brazilians underestimate. The rule is simple: IRCC takes your foreign offence, finds the equivalent Canadian offence, and treats you as if you had committed that Canadian offence. A bar fight in São Paulo can become an assault charge under the Canadian Criminal Code. A shoplifting incident in Florida can become theft under $5,000.
Serious criminality vs criminality
- Serious criminality (s.36(1)) applies to offences that would be punishable in Canada by a maximum term of at least 10 years, or where you were sentenced to more than 6 months of imprisonment. Permanent residents can lose status for this.
- Criminality (s.36(2)) applies to indictable offences with a maximum sentence below 10 years, or two summary convictions.
The DUI rule change you must know
Since December 18, 2018, impaired driving (DUI) in Canada carries a maximum penalty of 10 years. That single change reclassified DUI as serious criminality. A single DUI conviction in Brazil, the United States, or anywhere else can now make you inadmissible for serious criminality, not the lighter category. This catches a lot of Brazilians who picked up a DUI in Florida twenty years ago and assumed it was forgotten.
Deemed rehabilitation timelines
If your offence falls under simple criminality (not serious), you may be deemed rehabilitated by the passage of time:
- 5 years after completion of the sentence for a single non-serious indictable offence (equivalent), or
- 10 years for two or more summary offences (equivalent).
Deemed rehabilitation does not apply to serious criminality. If you have a DUI post-2018 classification, you cannot wait it out, you must apply for criminal rehabilitation.
The remedies
| Situation | Remedy | Processing time | Permanent? |
|---|---|---|---|
| Need to travel to Canada soon, conviction less than 5 yrs old | Temporary Resident Permit (TRP) | 4-12 months at visa office; same day at port of entry (risky) | No, valid for stated period only |
| Conviction more than 5 yrs old, single non-serious offence | Criminal Rehabilitation | 12-24 months | Yes, one-time fix |
| Single non-serious offence, 10+ years since sentence completed | Deemed rehabilitation (no application needed, but legal opinion letter recommended) | N/A | Yes |
| Serious criminality (DUI post-2018, sentence 10+ yrs) | Criminal Rehabilitation only (no deemed rehab) | 12-24 months | Yes |
| Very serious offence with active sentence | Generally not forgivable until sentence served + waiting period | N/A | Depends |
2. Medical inadmissibility under IRPA s.38
Medical inadmissibility covers three situations: danger to public health, danger to public safety, and excessive demand on health or social services. The first two are rare (active untreated tuberculosis, untreated infectious syphilis, conditions causing violent behaviour). The third one , excessive demand, is what trips most applicants.
The excessive demand threshold (2018 change)
In June 2018, IRCC roughly tripled the excessive demand cost threshold. For 2026, the threshold sits at approximately three times the Canadian average per-person health and social services cost, adjusted annually. The current figure is published by IRCC and updates each year, at the time of writing it is in the range of CAD $128,000 over 5 years, or CAD $25,000+ per year in projected cost.
Conditions that may still trigger a flag include:
- Cancers requiring ongoing expensive treatment
- Organ transplant follow-up care
- End-stage renal disease requiring dialysis
- Severe intellectual or developmental disabilities requiring extensive social services
- Some chronic conditions requiring specialized drugs (rare biologics)
What changed for HIV applicants
Since the 2018 reform, HIV is no longer an automatic flag. Treatment costs for HIV in Canada have dropped below the new threshold for the vast majority of applicants. HIV-positive applicants still complete the immigration medical exam, but a positive result alone does not trigger inadmissibility.
Exemptions
Excessive demand does not apply to:
- Refugees and protected persons
- Spouses, common-law partners, and dependent children sponsored under family class
- Certain humanitarian categories
If you are applying as an economic immigrant (Express Entry, PNP, work permit) or as a visitor, the excessive demand rule fully applies.
The remedy
A procedural fairness letter is your one chance to respond. You submit a mitigation plan showing how the costs can be reduced, whether through private insurance, family support, or treatment already covered. Mitigation plans require medical evidence and often a cost analysis from a Canadian specialist. This is not a do-it-yourself moment.
3. Misrepresentation under IRPA s.40
This is the most punitive ground because the bar is low and the consequences are heavy. Misrepresentation means directly or indirectly misrepresenting or withholding material facts that could have induced an error in the administration of the Act. Translation: even an honest mistake counts.
The 5-year ban
A finding of misrepresentation triggers a 5-year ban on entering Canada or applying for permanent residence. It also flags your record permanently. Future applications, even after the ban expires, face heightened scrutiny.
What counts as misrepresentation
- Failing to declare a prior visa refusal, for any country, not just Canada
- Omitting a marriage, divorce, or child from your application
- Submitting a fraudulent job letter or bank statement
- Failing to declare a criminal record (even if expunged in your home country)
- Failing to mention a prior Canadian visa application under a different name or spelling
- Not updating IRCC when circumstances change between submission and decision
"I didn't know" is not a defence
Officers regularly find misrepresentation even when the omission was unintentional. The standard is whether the omission could have affected the decision, not whether you meant to lie. A Brazilian applicant who forgets to declare a US tourist visa refusal from 2008 can still receive a 5-year ban in 2026.
The remedy
There is no formal "rehabilitation" for misrepresentation. The options are:
- Respond to the procedural fairness letter with evidence the omission was not material
- Wait out the 5-year ban
- Apply for Authorization to Return to Canada (ARC) if a removal order was issued
- Apply for permanent residence on H&C (Humanitarian and Compassionate) grounds in exceptional cases
4. Other inadmissibility categories
- Security (s.34): Espionage, subversion, terrorism. Includes past membership in organizations the Canadian government considers terrorist or subversive, even decades ago.
- Human rights violations (s.35): War crimes, crimes against humanity, senior official of a government engaged in gross human rights violations.
- Organized criminality (s.37): Membership in a criminal organization, transnational crime.
- Financial reasons (s.39): Unable or unwilling to support yourself and dependants. Rare as a standalone ground but cited in some refusals.
Security and human rights findings are extremely hard to overcome. They require Ministerial Relief, which can take years.
5. How IRCC actually checks
The myth that "they won't find out" died around 2015. In 2026, IRCC databases are interconnected with:
- Canadian Police Information Centre (CPIC)
- FBI and INTERPOL databases via information-sharing agreements
- Five Eyes partners (US, UK, Australia, New Zealand) for visa refusal history
- Biometrics shared across CBSA, IRCC, RCMP, and FBI
- Brazilian federal police (Polícia Federal) certificates verified through formal channels
- IRCC's own Global Case Management System (GCMS), every prior application, every refusal, every name variant
When you submit a Police Certificate (PCC) from Brazil, IRCC cross-checks it. When you list (or omit) prior US visa refusals, IRCC can verify through US data-sharing. Your medical exam goes through a panel physician whose results upload directly to IRCC.
6. What is forgivable
| Inadmissibility type | Short-term fix | Permanent fix |
|---|---|---|
| Criminal (non-serious, recent) | TRP | Criminal Rehabilitation after 5 yrs |
| Criminal (serious, DUI post-2018) | TRP (limited) | Criminal Rehabilitation after 5 yrs |
| Medical (excessive demand) | Mitigation plan response to PFL | Treatment plan, private insurance proof |
| Misrepresentation | None | Wait 5 yrs or H&C in rare cases |
| Financial | Updated proof of funds, sponsor | N/A |
| Security / human rights / organized crime | Ministerial Relief (very rare) | Ministerial Relief |
H&C applications under s.25 of IRPA can sometimes overcome inadmissibility, but they are discretionary and reserved for compelling circumstances: established life in Canada, children's best interests, country conditions in Brazil that make removal disproportionate.
7. What is NOT forgivable
- Convictions with a sentence of 10 years or more actually imposed
- Active involvement in terrorism, espionage, war crimes, or genocide
- Senior official roles in regimes designated under s.35
- Membership in organizations designated as terrorist by Canada
- Repeated misrepresentation across multiple applications
8. Brazilian-specific issues
A few patterns we see at our Abbotsford office over and over:
- Minor offences on the Brazilian PCC. A 2009 furto simples (petty theft) that the applicant assumed was wiped. It is not wiped on the Polícia Federal certificate, and IRCC will see it.
- Old US B1/B2 refusals. Many Brazilians applied for US visas in the early 2000s, were refused, and forgot. The IRCC form asks "have you ever been refused a visa to any country", answer truthfully every time.
- Undeclared prior Canadian visa applications. Common with applicants who used a different name spelling or a different consultant years ago. IRCC matches biometrics and date of birth.
- DUI in Florida or California from a vacation 10-15 years ago. Post-2018 reclassification means this is now serious criminality requiring rehabilitation.
- Medical results for a parent included in a PR application. Excessive demand assessments apply to all family members, even non-accompanying in some categories.
9. Always declare. Always.
The cost-benefit math is clear. If you declare a prior refusal or a minor offence, the worst case is that you need to address it with a legal submission or wait for a rehabilitation eligibility date. If you do not declare and IRCC finds out, and they will, the consequence is a 5-year misrepresentation ban that follows you for life. There is no scenario where hiding the issue ends better than disclosing it with the right legal framing.
10. Lawyer or RCIC?
This is a real question for inadmissibility cases. The rule of thumb we use:
- RCIC (Regulated Canadian Immigration Consultant): Clear-cut cases. Deemed rehabilitation eligibility, single old conviction with full sentence completion documented, straightforward TRP application, medical mitigation plans for moderate excessive demand cases. RCICs are licensed by the College of Immigration and Citizenship Consultants and can represent you before IRCC.
- Immigration lawyer: Complex criminality, Federal Court appeals, judicial review of refusals, security or human rights findings, deportation orders, criminal proceedings happening in parallel in Canada, H&C applications involving children's rights litigation.
For inadmissibility refusals where the next step is Federal Court, you need a lawyer. For preventing the refusal in the first place, which is the whole point of this article, an RCIC who works inadmissibility files regularly is the right call.

Don't apply blind
If you have a conviction, a prior refusal, a complicated medical history, or any doubt about what to declare, do not submit the application and hope. Get a file review first. A 60-minute consultation will either confirm you are clear or surface the exact remedy you need before IRCC opens your file.
Book a paid consultation with RCIC Larissa Castelluber (R710678) at our Abbotsford BC office: /immigration-consultation. We review your record, your prior applications, and your medical and criminal history, then give you a written assessment of risk and remedy.
