When the temperature drops to −20°C outside, heating the one room you’re actually using is one of the cheapest comfort upgrades there is. A 1500 W heater puts out roughly 5,100 BTU per hour — enough for a bedroom or small living room, following the rough rule of about 10 watts per square foot. We compared the best-regarded space heaters listed on Amazon.ca, from $25 desk warmers to silent oil-filled radiators, so you can match the heater to the room.

Amazon Basics Ceramic Space Heater, Mini 500W (Black)
Best budget pick — listed around $24.80 on Amazon.ca at research time
For warming your side of the home office, nothing beats a tiny 500 W cube. The Amazon Basics mini heater was the cheapest real pick we surfaced on Amazon.ca — listed around $24.80 at research time — with a buyable offer present and tip-over protection. At 500 W it sips power (about a third of a full-size heater), so it barely moves the electricity bill. Just know its limits: this is personal warmth for a desk or nightstand, not a room heater.
- Lowest price in this roundup
- 500 W barely moves the power bill
- Tip-over protection
- Tiny footprint for desks
- Won’t heat a room — personal use only
- No thermostat or timer mentioned
- Best as a supplement, not a primary heater

Best all-round pick — listed around $79.99 on Amazon.ca at research time; 4.6/5 from 904 ratings
The Dreo DR-HSH004 is the classic do-everything bedroom heater: 1500 W of ceramic heat, 70° oscillation to spread warmth, a remote, a 12-hour timer, and an ECO mode that adjusts output to the room temperature instead of cycling full-blast. It was listed around $79.99 on Amazon.ca at research time, with 4.6 stars from 904 ratings and strong recent buyer activity. If you buy one heater for a Canadian winter, this form factor is the safest bet.

- 70° oscillation spreads warmth
- 4.6/5 from 904 ratings
- Tip-over and overheat protection

GiveBest 800W Plug-in Wall Space Heater with Remote and Thermostat
Best specialty pick — listed around $62.67 on Amazon.ca at research time

The GiveBest 800 W wall heater includes a remote, an adjustable thermostat, a 12-hour timer and an LED display, and it was listed around $62.67 on Amazon.ca at research time.

- Zero floor footprint
- Remote and 12H timer included
- 800 W middle ground on power
- Adjustable thermostat
- Occupies a wall outlet
- Heats only a small zone

Buying guide: how to choose a space heater
- Safety first: in Canada, look for heaters that are ETL or UL/ULC listed, with tip-over and overheat protection. Plug the heater directly into a wall outlet — never into an extension cord or power bar.
- Wattage math: budget roughly 10 W per square foot. A 1500 W heater suits a ~150 sq ft bedroom or small living room; it will not heat a whole floor. A 500–800 W unit is a personal/desk heater, not a room heater.
- Oil-filled vs ceramic vs fan: oil-filled radiators are silent and keep radiating warmth after they cycle off, but warm up slowly — best for overnight. Ceramic/PTC heaters heat fast and oscillate — best for quick warm-ups. Plain fan heaters are cheapest but noisiest.
- Thermostat and timer: a real thermostat (not just high/low switches) and an auto-off timer cut the running cost dramatically, because the heater cycles instead of blasting continuously.
- Running cost: at Ontario electricity rates, a 1500 W heater running 8 hours a day can add $40–$60+ to a monthly bill. Pair it with the right electricity plan (see below) rather than running it around the clock.
Wondering what a heater does to your power bill?
A 1500 W heater running evenings through a cold snap can add $40–$60+ to a monthly electricity bill — and Ontario’s time-of-use, tiered and ultra-low overnight plans price that power very differently. Run our electricity plan picker to see which plan fits your usage before winter.
Frequently asked questions
How much does it cost to run a space heater in Ontario?
A 1500 W heater uses 1.5 kWh per hour. Multiply by your electricity rate (roughly 10–18¢/kWh depending on plan and time of day in Ontario) — that’s about 15–27¢ per hour, or $36–$65 a month running 8 hours a day. A thermostat and timer cut that substantially.
Are oil-filled radiators better than ceramic heaters?
They’re different tools. Oil-filled radiators are silent and hold heat longest, but warm up slowly — best for overnight bedrooms. Ceramic heaters warm a room fast and oscillate, but the fan makes noise and the warmth fades when they cycle off.
Is it safe to leave a space heater on overnight?
Only unattended-rated heaters with tip-over and overheat protection, plugged directly into a wall outlet, kept at least a metre from bedding, curtains and furniture. Never use an extension cord or power bar, and never leave a heater running in a room with unsupervised children or pets.
What size space heater do I need?
Budget roughly 10 watts per square foot: 1500 W for a ~150 sq ft bedroom or small living room, 750–800 W for a bathroom or office nook, 500 W for personal desk warmth. Oversizing wastes electricity; undersizing means it runs constantly.
