Public Utility Locate Service
There is buried infrastructure all over Ontario. You must contact Ontario One Call to get buried cables, pipes, and wires located so you can dig safely.
Ontario One Call is a public safety administrative authority and the communication link between those wanting to dig and buried infrastructure owners who are required to provide locates.
Ontario One Call does not physically mark the lines, pipes, or cables. We relay the dig information to the buried infrastructure owners so they can mark (locate) based on the request you submit.
Click Before You Dig
Damaging underground infrastructure is dangerous. Hitting wires, pipes or cables can cause serious injuries and carry hefty financial consequences.

When you see red and orange flags and/or paint, what does it mean?
When someone is planning to dig, Infrastructure Owners must provide locate responses for the infrastructure they own. Unless an infrastructure owner provides a clearance, locates come with field markings, usually flags and/or paint. These field markings come in different colours, as seen below, to help identify which utility type is buried under the ground in that location.
