Its the 21st annual McHappy Day today.
$1 from every Big Mac, Happy Meal, and McCafe will go to Ronald McDonald Houses and other local charities.
Sarnia McDonalds Owner/Operator Colleen Buckley says the annual event gets more and more popular every year.
This years local beneficiary will be St. Joseph’s Hospice.
Last year, about $16,500 was raised locally.
