Toronto 
Canadians planning to fill up their vehicles on Thursday may want to check the time before heading to the gas station.
Circle K is bringing back its National Fuel Day on October 15, 2026, offering a discount of 10 cents per litre at participating fuel stations across Canada.
The promotion runs from 3 p.m. to 7 p.m. local time, giving drivers four hours to take advantage of the reduced price.
The discount is applied directly at the pump, so there is no coupon to present for the main offer. For example, filling a 50-litre tank during the promotion would save $5.
Participating locations include Circle K and Couche-Tard-operated fuel stations.
Circle K is using the event to support children’s healthcare in Ontario.
For each fuel transaction completed during Fuel Day in the province, the company will donate $1 to local children’s hospitals, up to a maximum contribution of $50,000.
Western Canada Gets an Earlier Discount Window
Drivers in British Columbia, Alberta, Saskatchewan, Manitoba and the Northwest Territories have another opportunity to save earlier in the day.
Registered Circle K app users in these regions can receive the same 10-cent-per-litre discount between 11 a.m. and 2 p.m. local time on October 15.
Customers must download the app, register an account and log in to access the early offer.
The app promotion is limited to one redemption per account, with a maximum of 100 litres per vehicle. It cannot be combined with the afternoon Fuel Day discount.
