In most situations you should be prepared for a dunking, so you could hang around in the water and bail without getting too cold. Of course, if you're in danger (e.g. from hitting rocks) get yourself to safety with a swim line to the boat and recover it by swinging it into an eddy. If you're touring (including, even especially white water touring) all your gear should be packed in suitable containers (barrels/drybags) that float and are lashed into place -- thus your cargo adds bouyancy, though potentially not much. In the case of the bike, of course it's a deadweight and an encumbrance when trying to right the boat, so you'd actually need more bouyancy to counterract that.

There are big differences between the boat in your picture and a kayak:

• You'd fall out of the canoe if you capsized
• You can move around much more for balance (and may have to)
• You can get in and out more quickly
• Rigging and stowing a sail are much easier and much more stable on the canoe.
• The canoe is less manoeuvrable than the kayak
• You can carry a bike in a canoe!

Every gallon of dry storage adds 8.36 pounds of flotation (minus the weight of the container) a liter of dry storage adds a Kilogram of flotation. There are two sizes of food grade, air and water tight plastic barrels that are ready available in the "Used Once" market. 8 Gallon and 15 Gallon sizes are found in the US (ebay) for a reasonable price (~$25 with shipping).
