NOTE: Under municipal rules, blasting companies are required to complete a pre-blast survey for all structures within 75 metres of a blasting site, and are required to provide notification about the blasting to everyone within 150 metres of the blasting site. That’s a very small radius of notification, especially when blasting can be felt at distances of hundreds of metres. We’ve set up this page to list known blasting operations in the Stittsville area.

How does the City manage and regulate blasting?
- For developers, there is no formal approval to proceed with blasting as it is within their own property. The City has a blasting specifications that developer projects and City-led projects must follow, based on Provincial and Federal regulations.
- The specification requires that the developer/builder has a 3rd party blasting consultant retained to monitor the blasting activities. (This is also required for the blasting company in order to be insured.)
- The blasting company is required to complete a pre-blast survey for all structures within 75 metres of the blasting site. They are required to provide notification to everyone within 150 metres of the blasting site. The pre-blast survey is an internal and external inspection of the buildings. Many homeowners don’t permit the company within their house, but we advise that they do permit them.
- After the pre-blast survey is complete, the blasting monitoring company sets up monitors to monitor the blasts as there are restrictions within the City specification on the maximum vibration permitted. (These are based on Provincial and Federal regulations.)
How severe are the vibrations? How do they measure it?
Blast engineers will often place monitoring devices at various locations around the blasting site. The maximum allowable limit prior to damage is 50mm/s, and concrete and foundation cracks would occur over 100mm/s. The monitors have recorded vibration levels at 5mm/s and less, so property damage would not occur at these levels at this distance.
What if I suspect the blasting is causing damage to my property?
Any homeowner who believes their home may be damaged (or subject to damage) by the blasting should contact the blasting engineer. It’s recommended that you document any suspected damage by taking photos. You may also wish to inform your home insurance company.
Will the City help me out if the blasting has damaged my property?
The City does not advocate on a resident’s behalf with respect to damage caused by blasting. The City does not have the authority under provincial regulations to review suspected damages brought on by blasting. Residents should contact their insurance provider to initiate a claim.
This blasting is very disruptive! What am I supposed to do?
We know the blasting is unpleasant. And it’s especially disruptive when so many people are working from home during the pandemic. Unfortunately, it’s the quickest and least disruptive way to get this necessary construction work done. We are sympathetic to these concerns and thank residents for their patience as work continues in our growing community.
