Canada: Click Before You Dig
Whether you’re planting a tree, digging a trench or building a fence, you need to be aware of the underground utilities on your property before you dig. Call your local One-Call Centre or visit ClickBeforeYouDig.com three business days (five in Ontario) before starting your job.
United States: Know what's below. Call before you dig
Anyone who plans to dig should call 811 or go to their state 811 center’s website a few business days before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don’t unintentionally dig into an underground utility line.
