At Destination Pools & Landscaping, we spend a lot of time helping Toronto homeowners understand the different options available when building or upgrading a pool. One of the most common questions we hear is whether a salt water system or a traditional chlorine system is better for long-term comfort, maintenance, and backyard durability. Before choosing either option, it’s important to understand how each one works, how they differ, and what that means for your backyard materials and Toronto’s climate.
Salt water pools are still chlorine pools because they make their own chlorine using a saltwater generator. Traditional chlorine pools rely on chemicals that you add manually. Both systems keep your pool clean and safe, but they create very different ownership experiences. Understanding these differences helps Toronto homeowners make the right choice for their backyard layout, preferred maintenance level, and long-term budget.
Salt Water Pools Are Still Chlorine Pools
Many Toronto homeowners think salt pools are chlorine-free, but that isn’t true. Salt water pools use a Salt Water Generator (SWG) to convert dissolved salt into chrine through electrolysis. This chlorine sanitizes the water the same way as traditional chlorine but with fewer harsh byproducts and with more consistent output.
Choosing a salt system does not change the sanitizer. You are simply choosing a different way of producing and delivering chlorine.
Common Questions Homeowners Ask
Do salt water pools produce a different type of chlorine?
Yes. The chlorine produced by a salt system is generated in smaller, continuous amounts, which results in fewer chloramines.
Do salt water pools still need stabilizer (CYA)?
Yes. Stabilizer is needed to protect chlorine from sunlight.
Does the salt stay in the pool all season?
Mostly. You only add more when dilution happens from rain, backwashing, or splash-out.
Water Smell and Feel: Why People Prefer Salt Systems
A properly balanced chlorine pool should not smell like chlorine. Strong pool smells come from chloramines, which form when chlorine binds to contaminants such as sweat, sunscreen, or body oils.
Salt water pools tend to feel softer, smoother, and more comfortable. Many homeowners describe the water as silky. The salinity level, about 3,000 ppm, is mild enough that swimmers typically do not notice a salty taste. This softer feel is one of the biggest reasons families choose salt systems.
Salt water is also gentler on swimsuits, towels, skin, and hair. Swimmers often experience less dryness and irritation, which makes salt systems popular for families with kids or people with sensitive skin.

Common Homeowner Questions
Will salt sting cuts or irritate skin?
Not at the levels found in a pool. Most swimmers feel no discomfort.
Does a salt water pool taste salty?
It tastes slightly salty, but far less than ocean water.
Pros and Cons: Salt Water Pools vs. Chlorine Pools
Salt Water Pool Pros and Cons
| Salt Water Pool Pros | Salt Water Pool Cons |
|---|---|
| Softer, gentler water | Higher upfront cost (about 800 to 1,700 dollars for SWG) |
| Less eye and skin irritation | Salt can corrode metal and certain stone surfaces |
| No strong chlorine smell | Salt cells need replacement every 3 to 8 years |
| Automated daily chlorination | pH levels rise faster which requires frequent acid |
| Lower ongoing chemical cost | Not ideal for vinyl pools with metal wall panels |
| Easier for busy homeowners | Requires storing and handling large salt bags |
Chlorine Pool Pros and Cons
| Chlorine Pool Pros | Chlorine Pool Cons |
|---|---|
| Lower upfront cost | Requires manual chlorine dosing |
| No risk of salt corrosion | Can produce chloramines which cause smell and irritation |
| Works with all pool types | Water can feel harsher on skin and hair |
| Easy winterization in Toronto | More ongoing chemical handling |
| No special equipment to maintain | Higher annual chemical cost (about 250 to 350 dollars per year) |
Extra Considerations
- Salt water pools require a power source for the generator.
- Heavy pool use during hot weeks may require additional chlorine even in salt pools.
- Chlorine pools are simpler to manage during equipment repairs.
Maintenance Differences: What Toronto Homeowners Should Expect
Salt Water Pool Maintenance
Salt pools still require testing. You must maintain chlorine, salt levels, pH, alkalinity, calcium hardness, and CYA. Salt systems also cause pH to rise more quickly, so homeowners often add acid weekly or bi-weekly. The salt cell needs cleaning when scale builds up, typically every 500 hours, and must be replaced every 3 to 8 years.
Chlorine Pool Maintenance
Chlorine pools require tablets or liquid chlorine added manually. Homeowners must keep an eye on chloramines, test water regularly, and perform shock treatments when needed. Chlorine pools do not require specialty equipment like a generator or cell.
Common Questions
Does Toronto’s hard water affect salt systems?
Yes. It increases scale buildup and requires more frequent cell cleaning.
Do chlorine pools need more filter cleaning?
Filter maintenance is similar for both systems.
Costs: Upfront vs Long-Term
Salt Water Pool Costs
- Salt generator installation: typically $1,000
- Salt cell replacement: 300 to 600 dollars every 3 to 8 years
- Salt bags: 5 to 20 dollars per 40 lb bag
- Electricity use: slightly higher due to the generator
- Chemical costs: lower on average
Chlorine Pool Costs
- No generator required
- Annual chlorine cost: about 250 to 350 dollars
- Occasional shock treatments
- No cell replacements or generator repairs
Is salt cheaper long term?
Not always. Over a 10-year period, costs often balance out or salt may be slightly more expensive. The reason homeowners choose salt is convenience, not savings.

Corrosion and Material Considerations for Toronto Backyards
Salt can be corrosive when repeatedly splashed and left to evaporate on surfaces. This is important for Toronto homes because many backyards use natural stone or metal fixtures.
Materials at higher risk include stainless steel hardware, metal wall panels, stone like flagstone or limestone, steel ladders and bolts, and patio surfaces near the waterline.
How to Reduce Corrosion
- Seal stone surfaces every one to two years.
- Ensure proper drainage so salt water does not sit on surfaces.
- Choose non-corrosive hardware or composite materials when possible.
Common Questions
Is stamped concrete compatible with salt?
Yes, especially when sealed regularly.

Winterization in Toronto’s Climate
Toronto winters frequently fall below the operating temperature of salt generators. Most SWGs shut down at around 10 degrees Celsius. Once temperatures drop, the system stops producing chlorine entirely.
You must add traditional chlorine when closing the pool and monitor chlorine levels as the weather cools. Salt may also dilute slightly over winter due to snow, rain, or spring thaw.
Chlorine pools are generally easier to winterize because they do not rely on a generator.
Do salt levels drop over winter?
A little, typically due to dilution. Most homeowners top up salt levels in spring.
Clarity: Salt vs Chlorine Does Not Determine Clear Water
Cloudy water is caused by poor filtration, incorrect chemistry, low chlorine, high phosphates, high calcium hardness, or insufficient circulation. Both systems can produce crystal clear water when maintained properly.
Salt versus chlorine is not the deciding factor. Maintenance is.
Which System Is Best for a Toronto Backyard?
Choose Salt Water If You Want
- A softer swimming experience
- Lower daily maintenance
- Less noticeable smell
- Gentler water for kids and sensitive skin
- Automated chlorination
Choose Chlorine If You Want
- Lower upfront cost
- Less risk of corrosion
- Simpler winterizing
- No generator maintenance
