It's Shrove Tuesday or Fat Tuesday -- the day preceding Ash Wednesday to start the season of Lent.
And for many people -- it's also known as Pancake Day.
The Canadian Cancer Society is using the day to hold a fundraiser at Sunset Grill at Blue Mountains.
Pancakes are being sold for a dollar each at the restaurant as part of the 3rd annual Looney Pancake Tuesday event.
It runs from 7 AM until 3 PM and all of the proceeds today will be donated to the Canadian Cancer Society.
