Septic services in Canada encompass septic tank pumping, cleaning, repairs, and onsite wastewater treatment, serving the roughly 25 percent of Canadians not connected to municipal sewer systems. The trade is largely made up of small, independent operators spread unevenly across provinces, with concentrations in Ontario and British Columbia.
Demand for septic services peaks in spring—due to melting snow, high water tables, and failures—and again in fall when homeowners prepare systems before ground freeze. Demand dips in deep winter when frozen ground hinders access except for emergencies.
