Call before you dig

Planning a major landscaping, excavation or interior home renovation project?

Don’t forget to contact the Historic Waste Program Management Office
(HWP MO) before you dig!

Canadian Nuclear Laboratories (CNL), through the HWP MO, provides Construction Monitoring Program (CMP) services to property owners in urban Port Hope. There is no charge to have CNL take surface radiation readings and soil samples from your property to determine if the soil or building materials being encountered during the work are contaminated with historic low-level radioactive waste. If contaminated material is found, CNL will have it safely removed and if necessary, replaced – at no cost to you – so your project can continue.

The Construction Monitoring Program is part of CNL’s Interim Waste Management Program and is offered in parallel with the Property Radiological Survey underway as part of the Port Hope Area Initiative (PHAI). For more information on the Property Radiological Survey click here.

If you have any questions or would like to arrange for a CMP visit, phone 905.885.0291 or email
