Excavation in Ontario: questions
How much does excavation cost in Ontario?
Excavation in Ontario is quoted by the job or the machine day, not off a price list. A small residential dig commonly lands between $1,500 and $5,000; what moves it is access, how far the spoil has to travel, whether you hit rock, and what the CA permit and dig-safe process adds. Call two or three of the 10 contractors above and describe the same scope to each, or the numbers will not be comparable.
