It's McHappy Day today.
The 23rd annual event will see $1 from the sale of every Big Mac, Happy Meal or hot McCafe beverage go to the Lambton Kent chapter of the Canadian Mental Health Association.
More than 1,400 McDonald's country wide including Sarnia's four outlets will raise money to support local children's charities including Ronald McDonald House in London.
Owner of the Sarnia franchises Colleen Buckley says the national fundraiser has raised over $50-million over the 23 years.
