I wonder if it would conserve energy/heat if you were to use it foil side facing in on a inside ceiling to reflect radiant heat back into the house on a cold winters day..

or would using it foil side up on the inside ceiling be better in such a application ?
I think your idea should work. The problem is that it is generally recommended that at least 12" or so of insulation be on top of the ceiling to conserve heat. This is because this is the most effective way to trap the heat below and keep out cold. This is far more effective than a radiant barrier but far more costly. If you don't presently have insulation above the ceiling I would think you'd be freezing living in Vancouver. If you do have insulation then a radiant barrier would be an inconsequential addition to it. Also, there is the problem of the air space you would need between the barrier and the ceiling...
