Artificial Turf Rules in Ontario: Front Yards, Condos, Trees and Permits

For most backyards in Ontario, installing artificial turf needs no permit at all. But a handful of rules catch people out, and a few are expensive to get wrong. This guide sets out what to check, in roughly the order you'll meet it. It isn't legal advice, and rules vary by municipality and change over time, so confirm the details for your property with the body named.

1. Utility locates: always

Before any digging, book free utility locates through the Ontario Dig Authority, formerly Ontario One Call. A turf excavation goes 3 to 4 inches down, and gas lines, buried hydro, cable and fibre can be shallower than people expect, especially service lines running to the house. Locates take a few business days, so book early. A good installer books them for you; if you're doing it yourself, it's your job. Private lines, like a cable to a garage or a lighting circuit, aren't marked by utilities; a private locator can find them.

2. Front yards: check landscaping rules

Many Ontario municipalities require a minimum share of a front yard to be landscaped, and often a minimum share to be soft landscaping. Toronto's Zoning By-law 569-2013, for example, sets soft landscaping requirements for many front yards. Whether artificial turf counts as soft landscaping depends on how each by-law defines it. Before turfing a front lawn, ask your municipality's zoning office: 'Does artificial turf count toward the soft landscaping requirement for my lot?' Backyards rarely raise the question.

Separately, front-yard parking rules in some cities don't allow front lawns to be converted to parking pads; turf doesn't change that.

3. Trees

Several Ontario cities protect trees on private property, including Toronto, Mississauga, Oakville and Ottawa, each with its own size thresholds and rules. Removing a protected tree needs a permit, and so can injuring one, which includes cutting its roots. A turf excavation takes out the top few inches of soil, where a tree's feeder roots are. If a large tree is near the turf area:

• Check your municipality's current private tree rules before you dig.
• Ask the installer how they'll protect the root zone: shallower excavation near the trunk, keeping turf back, or hand-digging around roots.
• Don't change the grade around a tree's trunk.

4. Conservation areas, ravines and the escarpment

Properties near rivers, creeks, lakes, wetlands and valleys can fall in a conservation authority's regulated area, where changing grades or placing fill needs a permit. Toronto also has a ravine and natural feature protection by-law. Lots in the Niagara Escarpment Plan area can need a Niagara Escarpment Commission permit for site alteration, and Lake Simcoe shoreline properties come under the Lake Simcoe Protection Plan. An ordinary suburban backyard install rarely triggers any of these. A sloped lot backing onto a valley, a shoreline cottage, or any job that adds fill should be checked with the conservation authority first.

5. Lot grading and drainage

Every lot is supposed to shed water away from its buildings without dumping it on neighbours, and in newer subdivisions the grading was set by an approved plan. Turf mustn't change that pattern: don't raise the yard against a fence, block a swale with edging, or point the base's slope at a neighbour's lot. If your home is new and the builder still holds a grading deposit or the lot hasn't been certified, ask the builder before changing the yard. Municipal property standards and drainage by-laws apply to the result.

6. Septic systems

On rural and cottage properties, keep turf and its gravel base off the septic leaching bed. The bed needs soil and vegetation above it to work, and heavy equipment can damage it.

7. Condos and rentals

In most Ontario condominiums, balconies and terraces are exclusive-use common elements governed by the corporation's declaration, by-laws and rules under the Condominium Act, 1998. Many boards require written approval before anything is laid on a balcony, and some don't allow turf. Ask the property manager first. Tenants need the landlord's permission for any change to the yard. See balcony turf.

8. Heritage properties

Designated heritage properties and properties in heritage conservation districts can need approval for visible changes, which sometimes includes front-yard landscaping. Check with the municipality's heritage planning staff.

9. Playgrounds and child care

Public playgrounds and licensed child care centres in Ontario are built and inspected to CSA Z614, Canada's standard for children's playspaces and equipment, and licensed centres are regulated under O. Reg. 137/15 under the Child Care and Early Years Act, 2014. Surfacing under equipment must cushion falls from the equipment's fall height, so turf has to sit on a shock pad rated for it. Certified playground inspectors are trained through the Canadian Playground Safety Institute. See playground turf.

10. Commercial and indoor installs

In commercial buildings, interior finishes are subject to building and fire code requirements, and landlords, insurers and inspectors often ask for a turf product's fire test results. Ask the supplier for them before ordering. See indoor turf.
