In East Gwillimbury a hot tub needs no fence if its lockable cover holds at least 90.72 kg (200 lb) and stays locked whenever the tub isn't in use. The wiring is a separate job with its own ESA notification.
You've picked the tub and a delivery date. Two sets of rules now decide whether the install goes smoothly: the Town's pool by-law, which cares about who can fall in, and the Ontario Electrical Safety Code, which cares about who can get shocked. They are enforced by different offices, and passing one tells you nothing about the other.
The cover rule in By-law 2019-131
East Gwillimbury's Pool Enclosure By-law 2019-131 treats a hot tub as a pool. It defines a hot tub as an outdoor, jetted body of water and says the name covers "spas" and "whirlpools". A swim spa is covered too. A pool normally has to be completely enclosed by a pool fence (section 2.8).
Section 7.6 is the exception that matters to you: a hot tub or swim spa with a lockable cover capable of supporting at least 90.72 kg (200 pounds) does not need a pool fence or temporary enclosure. Section 7.7 attaches the condition: the owner must keep that cover securely closed and locked at all times when the tub is not in use.
- The cover has to do two things at once: take the weight and lock. A soft cover with no lock, or a lock you leave open, doesn't qualify.
- The condition is ongoing. The cover rule is a daily habit, not a one-time inspection.
Do you need a permit from the Town?
The by-law says nobody may keep a pool without a Pool Fence permit from By-law Enforcement Services (section 2.2), that the pool's location has to conform to the Zoning By-law (section 2.4), and that fees follow the Town's Fees and Charges By-law (section 2.5). Sections 7.6 and 7.7 take a locked, covered hot tub out of the fence requirement, but the by-law text doesn't say in so many words whether that also removes the permit step. Call By-law Enforcement before the tub arrives and ask two things: do you need anything on file, and does the spot you picked meet the setbacks.
The electrical side: a notification, not just a plug
The Electrical Safety Authority (ESA) says pool and hot tub installations usually involve both a building-side permit and an electrical permit, which ESA calls a notification of work, and that the electrical one is often overlooked, which puts the installer, the electrician and the property owner at risk. ESA treats a pool or hot tub at an existing home as a residential renovation, so the notification is filed through its residential process.
Two practical points follow. First, hot tub wiring is not a plug-in job: the work is regulated electrical work, so hire a licensed electrical contractor and verify them. Our guide on how to check a contractor's licence in Ontario shows where. Second, the work gets inspected, so keep the filing paperwork.
Bonding: the ring in the ground
An ESA technical podcast on the newer Code rules explains the part homeowners rarely hear about. Where a hot tub sits on the ground or on a concrete slab in contact with the earth, the Code now calls for a number 6 bond wire run around the tub. The ring extends 450 to 600 mm out from the tub, is buried at least 100 to 150 mm deep and is connected back to the bond in the tub itself. ESA's reason: everything within 1.5 m ends up at the same electrical voltage, which reduces shock risk. ESA's podcast says the ring isn't required if the tub sits on a wooden deck or other insulating material that extends one metre past it. ESA also says notifications filed on or after October 1, 2025 must meet the revised Rule 68-058 of the 2024 Ontario Electrical Safety Code.
That is why a "just set it on the old patio" plan can turn into a saw cut and some digging: on an existing slab the electrician has to cut a slot and run copper to the tub. Ask for the bonding to be in the quote, and ask the electrician which Code edition the notification falls under.
One more ESA clearance to plan around: existing electrical equipment should be at least 3 m from the tub unless a fence, wall or other permanent barrier separates them, and overhead powerlines need about 5 m. A meter, panel or outdoor outlet near your planned spot can change where the tub goes.
What about the deck underneath?
Plenty of tubs end up on a deck. The Town exempts a deck from a building permit only if it is uncovered, sits less than 600 mm above adjacent ground and isn't beside a required exit; replacing deck boards is also exempt. The Town's published exemption list doesn't mention hot tubs or their weight, so we can't tell you a filled tub leaves the exemption untouched. Ask Building Standards about the tub's filled weight, and keep in mind that a deck that doesn't meet the exemption needs a permit before you build it.
A short checklist before delivery day
- Confirm the cover is lockable and rated for at least 90.72 kg, and that you will actually lock it.
- Call By-law Enforcement about the permit and setbacks.
- Hire a licensed electrical contractor and check the licence number.
- Ask for the ESA notification and bonding to be in writing.
- Check the base: ground slab, or a deck that stays in the Town's exemption.
Quick answers
Does a hot tub need a fence in East Gwillimbury?
No, not if it has a lockable cover that supports at least 90.72 kg (200 lb). The cover must stay closed and locked whenever the tub is not in use. Without that cover, the tub needs a full pool fence.
Do I need a permit to install a hot tub in East Gwillimbury?
The Town's pool by-law counts hot tubs as pools, so call By-law Enforcement before you order. The electrical side separately calls for an ESA notification of work, which ESA says installers often overlook.
Does a hot tub need to be bonded?
Yes, if it sits on the ground or a slab touching the earth, the Code now calls for a number 6 bond wire ring around it. A tub on a wooden deck that extends one metre past it is exempt.
Who should wire my hot tub in Ontario?
A licensed electrical contractor, checked against the Electrical Safety Authority database. Hot tub wiring is regulated electrical work that needs an ESA notification and inspection. Rhodex can match you with a vetted electrician.
Can a hot tub go on my existing deck?
Only if the deck stays within the Town's permit exemption: uncovered, under 600 mm high, and not at a required exit. The list doesn't mention hot tub weight, so ask Building Standards first.
Before the truck arrives
The cover rule is simple and cheap to meet; the paperwork around it is where installs go wrong. Sort out the permit question, the electrical notification and the base first, and the tub is a quiet, uneventful addition to the yard.
