Does a concrete slab need footings below the frost line?
The slab would be for a storage shed, unheated and free standing. I would tend to go with concrete so it will serve as the floor, but if I have to set footings below the frost line, I think it would be too much work. In which case I would go with crushed gravel and frame the floor. My concern about that method would be animals getting in and making their home between the floor joists.

What is a footer in concrete?
The footer is a structural element that holds up the framing. The slab has no structural function, it is simply there to provide a hard walking surface. The goal of the footers is to make sure the building remains plumb and level, i.e. no settling, so the the footer needs to be large enough and deep enough to resist settlement under load, and typically has some rebar in it to provide tension strength in the concrete.#N#The slab can be poured with no rebar at all, which is typical. There is no reason to tie the slab in to the footers. This is not because the slab wants to move around with the seasons, concrete has a very low thermal coefficient of expansion, and should not "move" with the seasons. The slab should remain in place due to friction without need to connect to the slab, and since the slab is so thin (4 inches), it is not possible to place structural reinforcing in the slab.#N#Of course you want your slab to remain level and not settle, and that requires adequate preparation of the base material. You need to excavate down to natural mineral soil, backfill to appropriate grade using structural fill, compact the fill, then place your slab. Local building codes will typically dictate minimum excavation depth, minimum depth of fill, and the makeup of the structural fill. In earthquake zones, design of the footer and slab may be different, since the slab can be subject to severe tension loading during an earthquake, hence you may need steel reinforcing and probably a thicker slab than in standard practice. Or you may accept that the slab will be damaged in an earthquake, and plan to replace it. Best to talk to your building inspector, I am not sure what earthquake zone Vancouver is in.
What is the purpose of footers?

Drainage piping is laid on the foundation bed and the drain is positioned prior to the concrete pour.
What is steel reinforcement?
Steel reinforcing helps the foundation wall bear stress while mechanical vibration consolidates the concrete to eliminate voids and air bubbles that might weaken the concrete. Anchor bolts are installed in the concrete foundation to secure the garage walls to the foundation. The location and frequency of anchor bolts on the foundation wall is determined by local code. Farrell often uses insulation on the inside perimeter of the wall.
Why is radiant heat good for a garage?

Why should we go to just below frost depth?
The idea of going to just below frost depth is to prevent heaving. How is frost going to heave a whole building if it can't get beneathe it?
Does a slab need to be strong to withstand uneven heaving?
It's this differential heaving that's the main issue. The foundation and any slab needs to be strong enough to withstand the uneven heaving without cracking (or otherwise failing). (There's also the problem, on sloped sites, of having the foundation creep downhill over multiple freeze/thaw cycles. And one needs to consider the structure's relationship to other structures -- decks, patios, etc -- that it may connect to.)
Can you throw rebar into a shed?
It would be advisible to throw a few pieces of rebar or wire into the slab. That way, if it does crack, it won't go in two different direction and tear the shed apart.
Do you need a footing below the frost line?
No simple answer. Wether or not a footing is needed below the frost line depends on the soil, the moisture content and the timing of water infiltration and the movement of the frost line. In very general terms, coarse grained soils frost heave less than fine grained soils.
