That sharp “pool-like” smell from your tap can be especially noticeable in Kingston during the winter. If you’re in Bayridge, Williamsville, Collins Bay, or downtown near the Inner Harbour and you suddenly think, “Why does my water smell more like chlorine right now?”, you’re not imagining it.
In most cases, it’s a normal side-effect of how municipal water is disinfected and how our homes behave in winter, not a sign that something is “wrong” with Kingston’s water. Below is what’s actually happening, what’s considered normal, and the practical ways to improve taste and odour (without guessing).
Quick refresher: why chlorine is in Kingston tap water
Kingston is on municipal (city) water in most neighbourhoods, and disinfectant residual is used to keep water safe as it travels through pipes to your home. In Canada, drinking water treatment and monitoring is governed by multiple layers (Health Canada guidance and provincial oversight in Ontario through the MECP), and utilities maintain a disinfectant level to prevent microbial growth in the distribution system.
If you want the official backdrop, start with:
Chlorine (or chloramine, depending on the system) can leave a detectable taste or smell even when the water is safe.
Why you smell more “Kingston tap water chlorine” in winter
There are a few winter-specific reasons homeowners notice chlorine odour more strongly, especially during showers, dishwashing, or when you first turn on a tap.
1) Winter homes trap odours (less ventilation)
In summer, we open windows more often and run bathroom fans longer because humidity feels obvious. In winter, we seal up the house, and showers create warm steam that can carry “chlorine” off-gassing into the air.
Result: the water itself may not be dramatically different, but you smell it more.
2) Hot water releases chlorine faster than cold water
Chlorine compounds are more noticeable when water is heated or aerated. That is why the smell can spike:
- In a hot shower
- When filling a sink with warm water
- When running a dishwasher
Even if the cold tap seems fine, the same water can smell stronger once it’s heated.
3) Seasonal changes in source water and treatment targets
Utilities adjust treatment throughout the year based on real-world conditions such as:
- Water temperature
- Organic material levels
- Distribution system demand
In winter, water chemistry and system demand can shift, and a utility may maintain a different residual target to keep protection consistent to the “ends” of the network.
Bottom line: it’s common for disinfectant residual and detectability to vary seasonally, even within the normal operating range.
4) Plumbing “first draw” water can have a stronger smell
If a tap hasn’t been used overnight, the water sitting in your home’s plumbing can pick up more noticeable odour.
This shows up a lot in winter routines: less outdoor water use, fewer hose bibs running, and sometimes lower overall household water usage.
5) Your nose is different in winter
Dry indoor air, mild congestion, and warm shower steam can make certain smells seem stronger. This is surprisingly common, especially in households with kids bringing home winter colds.
Normal vs not normal: a simple guide
A chlorine smell is often normal, but it helps to know when to take the next step.
| What you notice | Most likely explanation | What to do first |
|---|---|---|
| Mild chlorine smell mainly in hot showers | Normal off-gassing, reduced winter ventilation | Run the bath fan longer, crack a window briefly, consider whole-home carbon filtration |
| Strong chlorine smell at one tap only | Local fixture issue (dirty aerator, biofilm) | Clean the aerator, flush the line, compare other taps |
| Sudden “chemical” smell across the whole house that’s much stronger than usual | Possible temporary change in residual, or a localized distribution event | Contact your municipal utility to report and confirm, then consider a water test |
| Rotten egg smell (sulphur) mostly in hot water | Water heater/anode reaction or sulphur bacteria (more common on wells) | Check if it’s hot-only, consider water heater inspection |
| Earthy/musty smell | Organic compounds (often seasonal) or plumbing biofilm | Flush, clean aerators, consider carbon filtration |
If you’re on municipal water in Kingston Proper, chlorine is the usual culprit for taste and odour complaints. If you’re outside the city on a private well (common in rural hubs), chlorine smell is less typical unless you’re actively chlorinating the well.

DIY steps to reduce chlorine taste and smell (fast)
If you just want the smell to calm down this week, start here.
Flush the “first draw” water
In the morning or after work, run the cold water for 30 to 60 seconds before filling a glass or kettle. This can reduce odour from water that’s been sitting in the line.
Clean faucet aerators and showerheads
Mineral scale and biofilm can hold odours.
- Unscrew the aerator
- Rinse debris
- Soak in vinegar (if safe for your fixture finish)
- Reinstall
If you’re in a hard-water area of Kingston (many homes are), scale can build up faster and make fixtures harder to keep “fresh.”
Use a vent fan longer in winter
For showers, a good rule is run the fan during the shower and for 20 minutes after. This is more about indoor air than water chemistry, but it makes a big difference.
Let drinking water “air out” (short-term trick)
Chlorine can dissipate from an open container.
- Fill a pitcher
- Leave it in the fridge (covered after it cools)
This is not a substitute for filtration, but it can help with taste.
The long-term fix for city water: whole-home carbon filtration (Halo)
If chlorine taste and odour is a recurring frustration, the most effective long-term approach for municipal water homes is typically a whole-home filtration system that targets chlorine and related compounds.
In Kingston, TapTech generally prioritizes Halo Water Systems for city water because they’re designed to improve:
- Chlorine taste and odour
- Overall water “feel” for bathing and laundry
- Scale protection (a common Kingston homeowner complaint)
A whole-home system treats water at the point it enters your home, so you notice it in:
- Showers (the biggest “chlorine smell” trigger)
- Kitchen and bathroom taps
- Washing machine and dishwasher

Whole-home filtration vs under-sink filters (what to choose?)
A lot of Kingston homeowners start with an under-sink carbon filter for drinking water, and that can help. But if the main issue is the shower smell (or dry skin, and the general “chlorinated” feeling), whole-home filtration is usually the better match.
Here’s a quick comparison:
| Option | Best for | What it won’t fix |
|---|---|---|
| Pitcher filter | Quick taste improvement | Shower smell, whole-home exposure |
| Under-sink carbon filter | Better drinking and cooking water | Bathroom chlorine odour |
| Whole-home carbon filtration | Shower odour, taste, whole-house protection | Does not “soften” hard water unless paired with softening/conditioning |
| Reverse Osmosis (RO) at kitchen sink | Highest drinking water refinement | Shower smell unless paired with whole-home filtration |
TapTech also installs reverse osmosis for homeowners who want excellent-tasting water at the kitchen sink, especially if you’re trying to cut bottled water.
What if you’re not on city water? (Napanee, Gananoque, rural wells)
If you’re outside Kingston Proper in places like Napanee, Gananoque, Inverary, Verona, or Harrowsmith, your water may come from a private well.
On well water, taste and odour complaints are often driven by different issues:
- Iron staining
- Sulphur (rotten-egg odour)
- Heavy hardness
- Low pH (aggressive, corrosive water)
For “aggressive” or challenging well water profiles (common in parts of Napanee and Gananoque), TapTech typically recommends Novo Water Conditioning because it’s built to address the real rural headaches, including iron and sulphur, not just taste.

When should you test your water?
If the chlorine smell is mild and consistent, it’s usually just a comfort issue. If it’s sudden, extreme, or paired with other symptoms, testing is a smart next step.
Consider testing if:
- The odour changed quickly and dramatically across all taps
- You notice staining, cloudiness, or sediment
- Neighbours in Portsmouth Village, Reddendale, or Cataraqui North report the same issue
- You’re on a private well (testing is essential for treatment design)

A neighbourly note on safety
People often equate “chlorine smell” with “unsafe.” In municipal systems, it’s usually the opposite: a detectable disinfectant residual often indicates the system is maintaining protection through the distribution network.
That said, you deserve water that tastes good and doesn’t stink up the bathroom every time you shower.
If your main goal is to reduce chlorine taste and odour in Kingston, a whole-home filtration approach (Halo) plus an optional RO system for drinking water is typically the cleanest, lowest-hassle path.
Frequently Asked Questions
Is it normal for Kingston tap water to smell like chlorine in winter? Yes, it can be normal. Winter homes are less ventilated and hot water releases chlorine odour more quickly, so you notice it more even if water quality is within normal parameters.
Why does the chlorine smell seem stronger in the shower than at the kitchen tap? Warm water and steam make chlorine compounds off-gas into the air, and bathrooms are small spaces. That combination makes the smell much easier to detect.
Can I remove chlorine taste and odour without buying bottled water? Usually, yes. Many homeowners use whole-home carbon filtration (for showers and whole-house taste) and add reverse osmosis at the kitchen sink for the best drinking water.
How do I know if it’s chlorine or sulphur (rotten egg smell)? Chlorine smells like a pool or disinfectant. Sulphur smells like rotten eggs and is often stronger in hot water, especially on well systems or when a water heater anode is reacting.
If I live outside Kingston on a well, should I treat chlorine the same way? Not exactly. On well water in areas like Napanee and Gananoque, odours are often iron or sulphur-related, and treatment is usually better targeted with a system designed for aggressive water, such as Novo, after proper testing.
