Solution 1Recommended

Save the PDF Directly from the Browser

Instead of clicking the link to open the PDF in the browser, force the browser to download the file directly to your computer.

Most browsers will try to open PDF files in a new tab by default. However, complex government forms like IMM 5644 contain dynamic features that standard browser PDF viewers cannot process, which makes the download appear to fail or display an error message.

1
Right-click the link

Navigate to the official Government of Canada website. Instead of left-clicking the IMM 5644 link, right-click on it to open the context menu.

2
Select 'Save link as'

Choose 'Save link as' (Chrome/Edge) or 'Save target as' from the dropdown menu to initiate a direct download.

3
Choose a local folder

Select a location on your computer, such as your Desktop or Downloads folder, to save the file and click 'Save'.

4
Open locally

Locate the saved file on your computer and open it using a dedicated desktop PDF reader rather than your web browser.

Tip: Always open the locally saved file by launching your PDF reader first and using the 'File' > 'Open' menu, or by right-clicking the file and selecting 'Open with'.

Frequently Asked Questions

Why do I get a 'Please wait' message when opening the IMM 5644 form?

This message appears when you try to open a dynamic XFA PDF form in a web browser that doesn't support it. You must download the file to your computer and open it with a dedicated desktop PDF reader like WPS Office or Adobe Acrobat.

Can I fill out the IMM 5644 form on my smartphone?

It is highly recommended to use a desktop or laptop computer. Mobile browsers and basic mobile PDF viewers often do not support the complex formatting and interactive fields required by official Canadian government forms.

What should I do if the form says it needs an update to the latest PDF viewer?

This indicates the software you are using cannot process the dynamic content of the form. Save the PDF locally and open it with a fully featured PDF reader that supports advanced forms, ensuring your software is updated to the latest version.
