Front Concrete Porch

Does a front porch require a foundation?

Currently my front porch is a solid mass of concrete, I would like to make it larger, it doesn't support anything basically just a deck, it currently doesn't have any foundation just a large solid concrete pad. What I would like to do is break it up, leave the old concrete there as fill and build a new concrete porch like you would build a floating pad for a shed

only thing is it's about a foot high.

Can it be built like a floating slab, 4" of concrete around the sides and top on top of fill, or does it need a footing?

I am in Southern Ontario
