This cornerstone event, the only one like it in Canada, puts the spotlight on front-line locators in the damage prevention industry, helping to promote the significance of their role in the excavating industry. At the Locate Rodeo, locators can come together and demonstrate their expertise and superior locating skills in a competitive and friendly environment.

DIRT Reporting

This chart illustrates a breakdown of the root cause subcategories for locating practices not sufficient for the past three years. The most prevalent root cause subcategory is facility marking or location not sufficient.  

There was a significant increase across all categories in 2017.

Turning Waste Into Value
Wessuc Inc.
Our keyhole coring process provides safe and quick access to underground utilities and enables localized excavation. We are equipped with hole plates that can safely cover the holes, allowing them to be immediately driven on. To compliment the coring service, Wessuc provides hydro-vac excavation services. Our combination wet/dry vac trucks break up soil using air/water while simultaneously excavating the slurry with a powerful vacuum. Wessuc is available for 24/7 emergency calls.

The spotlight was brightly focused on excavator operators, as well. The Excavator Challenge event complements the Locate Rodeo with a skills competition for those from the other side of the shovel. This year, competitors were municipality employees, infrastructure owners and utility contractors.

The deadline for submissions is Nov. 30, 2018.

Ear to the Ground

With nearly $1 billion of buried infrastructure, Guelph proposed an amalgamated locates system to provide economic efficiencies and reduce the risk of potential infrastructure damage due to the number of excavations performed each year.

Member News

Effective Aug. 16, 2018 Ontario One Call has released visibility of statuses to members notified on a locate request.


The Canadian Common Ground Alliance (CCGA) has launched a national monthly newsletter, Know What's Below. The newsletter is a way for regional partners — like the Alberta Common Ground Alliance (ABCGA) — to share news and updates with Common Ground Alliance members across Canada.


The Utility Engineering and Surveying Institute (UESI) offers professionals working within the utility, pipeline engineering and surveying/geomatics communities the opportunity to network with others and shape the future of the industry by participating in technical activities, conferences and the development of internationally recognized standards. The ORCGA looks forward to working alongside UESI and the firms that provide utility engineering.

As underground spaces are developed, many are wondering who really owns those spaces. How do we monitor and track everything from new transport excavations to mega-basements owned by billionaires? How do we map the structures beneath us?

In a city the size of Toronto, each time there’s an underground electrical cable strike, there’s a risk to public safety and potential for large-scale power outages that can affect residential customers, businesses and even public transit.

Find out what Toronto Hydro is doing differently to help reduce these incidents.





If you are looking to make contributions to the damage prevention industry through best practices, reporting and evaluation, or events and education, the ORCGA committees are looking for your input.

Education and Events Committee meetings: Sept. 12, Nov. 14

Reporting and Evaluation Committee meeting: Sept. 19

Best Practices Committee meeting: Sept. 26
