Gas vs. Electric Cars in Ontario: The Real Math Behind the Savings

Gas vs. Electric Cars in Ontario: The Real Math Behind the Savings

With the average price of regular unleaded gasoline in the GTA hovering around $1.60/L, many Ontario drivers are weighing whether switching to an electric vehicle (EV) truly makes sense for their monthly budget.

While EVs traditionally carry a higher upfront purchase or lease price, looking purely at the sticker price ignores the true cost of operation. When you factor in the massive difference in fueling costs—especially when taking advantage of Ontario's Ultra-Low Overnight (ULO) electricity rate of 3.9¢/kWh—the math tells a completely different story.

By installing a Level 2 home charging station paired with a smart electrical panel, you essentially build your own ultra-cheap fueling station right in your garage, insulated entirely from future pump spikes.

The Core Metrics: Fuel and Trip Cost Comparison

To understand where the savings come from, we have to look at the raw efficiency metrics of a standard internal combustion engine (ICE) crossover consuming an average of 8.5L/100km versus a Tesla Model Y consuming roughly 18 kWh/100km.

Per-Kilometer and Single-Trip Comparison

• Cost Per Kilometer: A standard gas crossover costs roughly $0.136 per km to fuel. By comparison, charging a Tesla Model Y overnight costs just $0.007 per km.

• The 500 km Cottage Trip: Driving a 500 km round-trip from the GTA up to Ontario’s cottage country costs $68.00 in gasoline. Making that exact same 500 km trip in a Tesla Model Y using overnight home charging costs a mere $3.50.

The Monthly Ledger: Real-World Cost Breakdown

Tesla Model Y vs. Comparable Gas Crossover (15,000 km/Year)

The table below breaks down the true monthly out-of-pocket costs for an average Ontario driver covering 15,000 km annually (1,250 km per month). It compares a promotional lease on a standard 2026 gas crossover (such as a Toyota RAV4 AWD at ~$121/week) against a baseline Tesla Model Y lease.

Monthly Cost Category	Standard Gas Crossover	Tesla Model Y (On ULO Rate)
Base Monthly Lease Payment	$525.00	$699.00
Monthly Fuel / Electricity Cost (1,250 km)	$170.00 (At $1.60/L)	$8.75 (At 3.9¢/kWh)
Routine Maintenance (Oil changes, engine filters)	$16.66 ($200/yr average)	$0.00
Total Monthly Out-of-Pocket Cost	$711.66	$707.75

The Real Financial Verdict

Even though the Tesla Model Y lease is $174.00 more expensive per month on paper, it actually ends up cheaper to operate overall once energy and maintenance savings are considered. You completely erase the lease premium through:

• $161.25 saved in monthly fuel costs.

• $16.66 saved by eliminating oil changes and basic engine wear.

Ultimately, you drive a premium, future-proof electric vehicle for a lower net monthly cost than a standard gas crossover.

Automating Your Savings with Smart Panel Control

To ensure you hit that ultra-low $8.75 monthly charging bill, your EV must pull power strictly during the province's designated ULO window (11 PM to 7 AM). Managing this manually can be a headache, but a Leviton Smart Panel automates the entire process. Operating as your home's central energy manager, it schedules your EV charger, heat pump, and high-draw appliances to activate exclusively when grid rates plummet, making true energy independence effortless.
