I live in southern Ontario too (dumb eh?) and I too am affected by barometric changes, up or down it doesn't matter. I have noticed though that out West, where the barometer changes by the minute, I don't feel it the same. I talked to the doc and he said the bad air in Ontario is bringing out more of our complaints and that I should MOVE (he said it with a grin) and to be honest we plan to. It will be a couple of years unfortunately but we will go and I'll try to spend more time out there visiting my daughter.

So, to get to the point, I think climate has an effect. Not just sure what or how though.
