Ontario One Call is now operating as Ontario Dig Authority.

On October 1, 2026 Ontario One Call is launching a new organization name now known as Ontario Dig Authority. This is a brand change, not an operational change. Rules, regulations, compliance obligations, response expectations, and processes remain unchanged. 

The updated brand is intended to:  

• Create clearer public understanding
• Improve consistency across communications
• Better reflect the organization’s role today
• Support stronger awareness and education efforts across the sector 

The rebrand does not change: 

• Rules or regulations
• Locate request processes
• Compliance obligations
• Response expectations
• Operational standards
• Existing responsibilities under the OUINS Act

Before you start any digging around your house or business you must have locates for hydro, gas, cable, telephone, water, sanitary.

If you do not obtain locates you may cause damage and there may be a fine, fees to repair damaged utilities, and more. However, the most important reason to get locates is to put safety first!

Ontario Dig Authority will need to know the following information:

• How deep will you be digging (in feet)?
• What is the full address where you will be digging?
• What is the telephone number at the dig site address (not a cell phone number)?
• What is the nearest intersecting road?
• Did you mark the area where you will be digging (with white paint or stakes)? (Yes? No?)
• Where on the property will you be digging? (Front, rear, or side)
• Will you be digging by machine or by hand?
• Date you plan to start digging. (require a minimum of one week after you call)

Ontario Dig Authority will provide a confirmation number be sure to write this information down.

If you are the Contractor ensure you have the locate paperwork at the job site while working.

It is also the law under the Ontario Occupational Health and Safety Act: all underground utilities must be located before you dig.
