@Joe Nation,
I don't think I agree with that, Joe, but it may be a local usage thing.
I think it shows emphasis, sure, but not THAT much. In my book, it could just be a more interesting way of playing out the narrative.
"I always hankered after an extended trip to Canada, and eventually to Canada I did go".
(thinks: that sentence would be quite unremarkable, and not materially changed, if the second "to Canada" was missed out.)
