Induction cooking heats your pan directly with a magnetic field, so it is faster, more precise and more efficient than both gas and conventional electric stoves. For most Canadian households it is worth considering whenever your current range needs replacing, and it is a key step if you are moving your home off fossil fuels. The main hurdles are the up-front price, compatible cookware and, in some homes, electrical capacity.
Key takeaways
- Induction transfers roughly 80–90% of its energy into the pan, compared with roughly a third for a typical gas burner.
- It boils water very quickly, gives fine low-heat control, and the cooktop surface stays cooler than a radiant element.
- You need magnetic cookware: if a fridge magnet sticks firmly to the bottom, it works.
- A full induction range generally needs a 240 V circuit; check panel capacity before you buy.
- Approximate cost: about $1,200 to $3,500 for a range, plus any electrical work.
How induction works
Under the glass of an induction cooktop sit copper coils. When you turn on a zone, an alternating current in the coil creates a rapidly changing magnetic field. That field induces an electric current in the base of a magnetic pan, and the pan's own resistance turns that current into heat.
The result: the pan heats up, not the cooktop. The glass only gets warm from contact with the hot pan. That is why induction is efficient, and why spilled food is less likely to burn onto the surface.
Induction vs gas vs electric
| Feature | Induction | Gas | Radiant electric (coil or glass) |
|---|---|---|---|
| Approximate energy delivered to food | ~80–90% | ~30–40% | ~70–75% |
| Speed to boil | Very fast | Moderate | Slow to moderate |
| Low-heat control | Excellent, instant | Good | Slow to respond |
| Surface heat | Low (pan heats only) | Open flame | Hot surface for a while after use |
| Combustion in the kitchen | None | Yes | None |
| Cleaning | Easy flat glass | Grates and burners | Easy (glass) to fiddly (coils) |
| Approx. range price | $1,200–$3,500 | $900–$3,000 | $600–$2,000 |
Efficiency figures are approximate and vary by appliance and pan.
Air quality and comfort
Gas stoves burn fuel indoors, producing combustion byproducts such as nitrogen dioxide and carbon monoxide along with heat and moisture. A properly vented range hood that exhausts outdoors helps, and you should always use it when cooking with gas. Induction has no combustion, so it removes that source entirely, though you still need ventilation for the smoke, grease and moisture that cooking itself creates.
Induction also keeps the kitchen cooler in summer, because less heat spills into the room. That is a small but welcome bonus if you have air conditioning or a heat pump doing the cooling.
What it costs to switch
All figures are approximate and vary by region and home.
- Induction range or cooktop: roughly $1,200 to $3,500, with premium models higher.
- Portable single-burner induction plate: roughly $80 to $250, a great way to test induction before committing.
- New 240 V circuit: if you are replacing a gas range, you will likely need one. Expect several hundred to around $1,500, depending on distance from the panel.
- Panel upgrade: only if your panel lacks capacity. Costs vary widely, often a few thousand dollars. Load management devices and smart panels can sometimes avoid a full upgrade.
- Cookware: many households already own compatible stainless or cast iron pieces. Replacing a few aluminum or copper pans is usually the only extra cost.
Operating costs depend on local electricity and gas prices, but cooking is a small share of most home energy bills, so do not expect large savings on the stove alone. The bigger financial win often comes if dropping the stove lets you close your gas account entirely, which eliminates the fixed monthly gas delivery charge. Our room-by-room electrification plan shows how the kitchen fits into that bigger picture.
Cookware: the magnet test
Hold a fridge magnet to the bottom of a pan. If it sticks firmly, it will work on induction.
- Works: cast iron, enamelled cast iron, carbon steel, most stainless steel labelled "induction ready".
- Does not work: plain aluminum, copper, glass and ceramic, unless the base has a magnetic layer.
- Workaround: an induction interface disk lets you use non-magnetic pans, though it reduces efficiency.
Flat-bottomed pans give the best contact and most even heat.
Common concerns
Noise
Induction can produce a faint hum or buzz, especially at high power or with lighter pans. Cooling fans also run during and after cooking. Most people stop noticing quickly.
Learning curve
Induction is fast. Oil heats in seconds, so stay close to the pan until you know your cooktop's power levels.
Medical devices
Manufacturers generally advise people with pacemakers or other implanted medical devices to check with their doctor and the device maker before using induction. This is general information, not medical advice.
Power outages
Like any electric stove, induction will not work without power. If outages are common where you live, a camp stove used outdoors, or a home battery, can be part of your backup plan; see our page on Canadian energy and the future grid for how resilience is evolving.
Rebates and timing
The cheapest moment to switch is when your current range is near the end of its life. Some provincial and utility programs have offered incentives for induction appliances or for whole-home electrification, but these change often.

Frequently asked questions
Is induction more expensive to run than gas?
It depends on local prices. Induction uses much less energy to do the same cooking, which narrows or erases any price gap per unit of energy, and cooking is a small part of most bills either way.
Can I install an induction cooktop on a 120 V outlet?
Full-size ranges and cooktops generally need a dedicated 240 V circuit. Portable single-burner units run on a standard 120 V outlet.
Does induction scratch easily?
The glass is durable but can scratch if you slide heavy cast iron across it. Lift pans rather than dragging them, and clean the surface regularly.
The bottom line
Induction is the most efficient, responsive way to cook on electricity, and it removes combustion from your kitchen. If your range is aging or you are planning to go all-electric, induction is worth a serious look; try a portable burner first, check your panel capacity and cookware, and time the switch with your next renovation or replacement.
