Toddlers are fascinated by water. They will splash in puddles, lean over bucket edges, and wander toward pools with absolute confidence and zero understanding of the risk. This combination of curiosity and unawareness makes children between the ages of one and four the highest-risk group for drowning in Canada.

Water safety for toddlers is not a single rule — it is a system of overlapping protections across every environment where water is present, from the bathtub to the backyard pool to the family beach trip. This guide covers all of them.

Bathtub Safety

The bathtub is where many parents let their guard down. The child is in a controlled space, the water is shallow, and you are right there. But a toddler can drown in as little as 2.5 centimetres (one inch) of water — barely enough to cover their nose and mouth if they slip and fall face-first.

• Never leave a toddler alone in the bath — not even for a few seconds. If the phone rings, the doorbell sounds, or you need to grab a towel, wrap the child in a towel and take them with you
• Bath seats and rings are not safety devices — they can tip over, and a child can slip out of them. They create a false sense of security. Use them for comfort and positioning only, never as a substitute for supervision
• Run the cold water first and add hot water gradually. Test water temperature with your elbow or a bath thermometer — it should be between 37-38°C (98-100°F). Toddler skin burns at lower temperatures than adult skin
• Keep the water shallow — for toddlers, bath water should be no deeper than waist level when they are seated
• Drain the tub immediately after bath time. A tub with water in it is an open invitation for a toddler who wanders into the bathroom unsupervised

Backyard Pool Safety

If you have a pool — including an above-ground pool, a blow-up wading pool, or a hot tub — your property requires specific safety measures.

Fencing and Barriers

A four-sided isolation fence around the pool (separate from the house) with a self-closing, self-latching gate is the single most effective physical protection against toddler drowning. Many Ontario municipalities require pool fencing by bylaw, though specific requirements vary. At minimum, your fence should be at least 1.2 metres (4 feet) high, have no horizontal rails a child can climb, and have a gate that opens away from the pool with a latch beyond a child’s reach.

Pool Rules for Families with Toddlers

• Designate a “water watcher” who does nothing else — no phone, no book, no conversation
• Keep rescue equipment (reaching pole, life ring) at the pool at all times
• Ensure all toddlers wear a Transport Canada-approved PFD (not water wings or inflatable rings)
• Teach toddlers to never approach the pool without an adult
• Install a pool alarm that sounds when the surface is disturbed
• Keep pool covers fully on or fully off — a partially deployed cover can trap a child underneath
• Lock hot tub covers when not in use

Beach and Lake Safety

Open water introduces risks that pools do not: currents, sudden depth changes, cold water, uneven and slippery surfaces, and limited visibility beneath the surface.

• Swim only at supervised beaches with lifeguards on duty. Obey all posted warnings and flags
• Stay within arm’s reach of your toddler at all times in or near the water
• Use a PFD — even in shallow water at the lake edge, where a toddler can trip and fall face-down
• Check for hazards — broken glass, sharp rocks, submerged logs, drop-offs, and strong currents
• Watch for cold water symptoms — Canadian lake water, even in summer, can be cold enough to cause muscle cramping and rapid fatigue. If your child’s lips turn blue or they start shivering, bring them out of the water immediately and warm them with dry towels
• Never let a toddler walk on docks, piers, or boat ramps without a PFD and hand-holding

Water Play and Containers

The dangers are not limited to pools and beaches. Any container that holds water is a potential hazard for a toddler.

• Buckets — a five-gallon bucket with a few inches of water is a drowning hazard for a toddler who leans in to look. Empty all buckets immediately after use and store them upside down
• Pet water bowls — large dog bowls can hold enough water to cover a baby’s face. Consider elevated or spill-proof bowls while your children are young
• Rain barrels and water features — secure rain barrels with locked lids. Decorative ponds and water features should be fenced or covered until children are older
• Coolers — after a party, empty coolers of melted ice water. A toddler can tip headfirst into a cooler and become trapped

Teaching Water Awareness to Toddlers

You cannot “drowning-proof” a toddler through lessons alone — no child under four has the cognitive and motor development to save themselves in water. But you can begin building water awareness early:

• Enrol in parent-and-child swim familiarisation classes (available for children 6 months and older)
• Teach “feet first” — entering water feet-first, never headfirst
• Teach them to always ask an adult before going near water
• Practise reaching for the wall — in a pool, show them how to grab the edge
• Make water rules consistent — the same rules apply at home, at grandma’s house, and at the hotel

If a Toddler Goes Under: Emergency Response

1. Get them out of the water immediately
2. Check for responsiveness — tap their shoulders and call their name
3. If unresponsive, call 911 (or have someone else call while you start CPR)
4. Begin infant/child CPR — 30 compressions to 2 breaths. Push hard and fast on the centre of the chest, at least one-third the depth of the chest
5. Continue until paramedics arrive or the child starts breathing on their own
