Amend special vehicle permits without retyping carrier particulars

Carriers repeat legal business name, address, contact information, and permit identifiers on every Special Amendment to an existing special vehicle permit. This guide is an example of storing them once in hivi.

Official form and source

Start from the official source and always use the current version — form numbers and links can change:

• Service page: Get an oversize/overweight permit — ontario.ca
• Form (Central Forms Repository): Special Amendment — sr-e-503

What this form is about

Form sr-e-503 amends an existing special vehicle or oversize permit — confirm which permit types can be amended on ontario.ca.

Before you start: what to gather

• Carrier legal name and business address.
• Contact details including phone and email.
• Existing permit number and amendment description.
• Revised dimensions or routes — confirm on ontario.ca.

How hivi makes it faster

1. Save it once. Store your carrier name, address, and contact details in your hivi profile.
2. Keep documents ready. Upload supporting documents to hivi Files so you are not searching at form time.
3. Autofill the form. Use the hivi Chrome extension on a web form, or fill a PDF from your saved profile inside hivi.
4. Review and submit yourself through the official channel.
