A letter of explanation can help you give Immigration, Refugees and Citizenship Canada (IRCC) additional context about information or documents in your immigration application. It may be useful when something cannot be fully explained in an application form, when a required document is unavailable, or when a discrepancy needs clarification.

A letter of explanation does not replace required evidence. Its purpose is to help the reviewing officer understand your circumstances and the documents you have submitted.

Quick Answer

A letter of explanation should clearly identify the issue you need to explain, provide the relevant facts and point the officer toward any supporting evidence you have included. Keep it focused on information that is relevant to your application.

IRCC allows online applicants who want to provide additional information about their case to create a separate document and upload it through the letter of explanation option in the optional documents section, where that option is available.

Why Does a Letter of Explanation Matter?

Immigration applications do not always fit neatly into forms and document checklists.

You might have a legitimate gap in your documentation, a difference between two records or circumstances that require more context than an application field allows. A letter gives you an opportunity to explain that information rather than leaving the officer to interpret the discrepancy without context.

IRCC itself describes a letter of explanation in some application guidance as an opportunity to make the processing officer aware of important information and avoid possible confusion.

The letter should support a complete and accurate application. It should not be used to hide missing information or replace evidence that you could reasonably provide.

When Might You Need a Letter of Explanation?

Whether you need one depends on your application and circumstances. Common situations can include:

• explaining why a required document cannot be provided
• clarifying differences between documents
• providing additional information that does not fit in an application form
• explaining changes to personal information
• giving context to unusual circumstances relevant to the application
• explaining an issue specifically identified in your program instructions

For example, IRCC’s parent and grandparent sponsorship guidance instructs applicants to provide explanations in circumstances such as certain name discrepancies, incomplete family birth dates and changes from information previously submitted.

IRCC also specifically allows applicants to provide additional details about their case on a separate document when completing an application.

What Should a Letter of Explanation Include?

There is no single universal template that applies to every Canadian immigration application. What you include should depend on the issue you need to explain.

A clear letter of explanation can generally be organized like this:

1. Applicant details: Include the information needed to clearly identify you and, where relevant, your application.
2. Purpose of the letter: Briefly state what you are writing to explain or clarify.
3. Explanation: Describe the relevant facts clearly and in a logical or chronological order.
4. Supporting evidence: Identify any documents you have included that support your explanation.
5. Closing: Briefly summarize what you want IRCC to understand or consider.

Keep the structure simple and focused. An immigration officer should be able to quickly understand what the issue is, why it occurred and which documents support your explanation.

How Should You Structure the Letter?

Start by identifying the subject you are addressing. Then explain the circumstances in a logical order.

For example, if two documents show different versions of your name, explain which documents are affected, why the difference exists and what evidence you have provided to establish the correct information.

If a document is missing, identify the document, explain why you could not obtain it and describe any steps you took to try to get it. Where appropriate, identify the alternative evidence you are submitting.

This is more useful than providing a long general account of your immigration plans that does not directly address the issue.

How Long Should a Letter of Explanation Be?

There is no universal length that every letter must follow. The appropriate length depends on what you need to explain.

A straightforward discrepancy might require only a few paragraphs. A more complicated situation could require a longer explanation and several supporting documents.

The priority should be clarity rather than length. Include enough information to explain the issue properly, but avoid unrelated details that make the important facts harder to find.

What If You Cannot Provide a Required Document?

This is one of the situations in which a letter of explanation can be particularly important.

Some IRCC application instructions specifically tell applicants to provide a written explanation when they cannot submit a required document. For example, the parents and grandparents sponsorship document checklist states that an applicant who cannot provide one or more required documents must upload a written explanation for each missing document.

However, providing an explanation does not automatically mean IRCC will accept the missing document.

Where possible, explain:

• which document is unavailable
• why you cannot obtain it
• what steps you took to obtain it
• whether you expect to obtain it later
• what alternative evidence you have provided

Keep evidence of your attempts where relevant.

Can You Use a Letter of Explanation for a Missing Police Certificate?

In some circumstances, yes, but the requirements can be specific.

For Express Entry, IRCC states that if an applicant cannot obtain a required police certificate by the application deadline, they can provide a letter of explanation together with proof showing that they made their best effort to obtain the certificate on time. An officer then reviews the application and may still reject it as incomplete if they are not satisfied with the efforts made.

This illustrates an important principle: the explanation itself is not necessarily enough. Supporting evidence can be crucial.

Can You Explain Problems With Employment Evidence?

If you are claiming work experience but cannot obtain the employment evidence normally expected, clearly explaining the problem may help IRCC understand the documents you have submitted instead.

For example, an employer may have closed, a former employer may refuse to issue a detailed letter, or company policy may limit what HR will confirm.

Our guide to What Should an Employment Reference Letter for Canada Include? explains what applicants should consider when preparing employment evidence.

If an expected employment document is unavailable, identify the problem accurately and provide legitimate alternative evidence where your program instructions allow it. Do not create or alter employer documents yourself.

Can a Letter Explain Inconsistencies Between Your Documents?

Yes, a letter can be useful when there is a genuine discrepancy that requires context.

IRCC’s parent and grandparent sponsorship guidance, for example, says applicants can provide a letter of explanation when there is a discrepancy between legal documents, such as differences involving a name.

The best approach is generally to identify the discrepancy directly rather than hoping it will not be noticed.

State what differs, explain why and provide supporting evidence where available. The explanation should also be consistent with the information elsewhere in your application.

Can You Use a Letter of Explanation for Family Information?

Family information can appear across several immigration forms and supporting documents. If there is a genuine circumstance that needs clarification, an explanation can help provide context.

However, the letter should not be used instead of declaring family information required by IRCC.

For example, applicants completing IMM 5406 Additional Family Information must still provide the family information requested by that form. If something about that information requires additional context, the explanation can accompany the required information rather than replace it.

The same principle applies to other forms, including IMM 5669 Schedule A.

Should You Include Supporting Documents With Your Letter?

When documents are available and relevant, they can make the explanation more useful.

The appropriate evidence depends on what you are explaining. It could include records showing attempts to obtain a missing document, legal documents explaining a name change, employment records supporting your work history or other evidence directly connected to your explanation.

IRCC’s guidance for changes in parent and grandparent sponsorship information, for example, tells applicants to provide both a letter explaining the changes and proof of those changes.

Rather than attaching large amounts of unrelated material, focus on evidence that supports the specific facts discussed in your letter.

Where Do You Upload a Letter of Explanation?

The correct upload location depends on the application.

For some online applications, IRCC provides a Letter of Explanation option under optional or additional supporting documents.

In other circumstances, IRCC may instruct you to upload the explanation in the field associated with a particular missing document. For example, Express Entry applicants who cannot obtain a police certificate in time are instructed to upload their explanation and proof in the country-specific police certificate field.

Follow the instructions in your application portal, personalized document checklist and program guide rather than assuming every letter should be uploaded in the same place.

What If IRCC Asks for an Explanation After You Apply?

IRCC may contact you during processing if it needs further information or documents.

If you receive an IRCC Additional Document Request, respond according to the instructions and deadline in the request. Address what IRCC has actually asked for rather than sending a general explanation.

A request for additional information is also different from a Procedural Fairness Letter. A procedural fairness letter can raise concerns that may affect the decision on an application, so the response needs to address those concerns carefully.

Is a Letter of Explanation the Same as GCMS Notes?

No. They serve completely different purposes.

A letter of explanation is information you provide to IRCC to clarify something about your application.

GCMS notes are records from IRCC’s Global Case Management System that can contain information recorded during the processing of an immigration or citizenship application.

Applicants should not confuse providing an explanation proactively with obtaining information about how an application has been processed.

How Does a Letter of Explanation Fit With Your Supporting Documents?

Think of the letter as context for your evidence, not as evidence of every fact on its own.

Your application may include identity documents, employment evidence, police certificates, family information and other supporting records depending on the immigration pathway.

Our guide to the documents needed for a Canadian visa provides a broader look at preparing immigration documentation.

Your letter should help connect relevant information when something genuinely requires clarification. It should not make an otherwise straightforward application more complicated.

Common Letter of Explanation Mistakes to Avoid

Writing a vague explanation: Clearly identify the issue and the facts the officer needs to understand.

Replacing evidence with an explanation: If a document is required and available, provide it. A letter should not be treated as an easier alternative.

Including irrelevant information: Keep the letter focused on the issue that needs clarification.

Ignoring a discrepancy: If two documents genuinely conflict, explain the difference and provide evidence where possible.

Making claims without supporting them: When evidence is available, include it and make clear how it relates to your explanation.

Submitting information that conflicts with your application: Review the letter against your forms and supporting documents before uploading it.

Assuming the upload process is always the same: Follow the instructions for your specific application and document checklist.
