Ontario drivers can save 10¢ per litre at the pump with Circle K’s Fuel Day on May 21

Ontario drivers, it’s time to get excited about a very special savings event happening directly at the gas pumps. Put the key in the ignition and get going — you’ll want to head over to Circle K for Fuel Day. 

Running from 3 p.m. to 7 p.m. on Thursday, May 21, drivers can score a 10 cent per litre discount. For just four hours only (an hour longer for 2026!), Circle K’s is bringing unbeatable value to customers.

Amplifying your dollar  

The generosity also continues beyond the pump: Circle K is partnering with local children’s hospitals in Ontario. During the four-hour event, $1 from every fill-up will be donated, up to a total of $50,000, to support vital children health programs in the community.

On top of this, Circle K Froster Active Kids will be matching donations up to an additional $50,000. That means there’s a total of up to $100k to be donated to children’s hospitals in Ontario. It’s all about amplifying the impact of your fuel purchase and spreading care. 

Summer-long savings

As we look forward to the upcoming summer season, drivers can continue to find more savings at Circle K with the Fuel Your Summer Sweepstakes. From May 26 to July 20, customers can enter for a chance to be one of 200 lucky winners of a Circle K $450 gift card. 

Just scan the QR code at the pump or in-store.

So, mark May 21 on your calendar and get down to your local Circle K for major fuel savings. Not only does it help your wallet, but your contribution also helps fund important causes right in the community — it’s a win-win!
