Vine with blue berries- unknown

Found this mystery vine growing along some railway tracks north of Toronto. I dug it up and transplanted it in my garden last fall. It's about 10' tall....any ideas, the leaves look something like a clematis vine.
Thanks, John

 

Well, since all you ask for are ideas, not knowledge, I'll start.

Smilax?

See http://www.nps.gov/plants/pubs/chesapeake/plant/2024.htm

 

Might be Smilax herbacea

 

Hi Ken,
I think you hit it right on the picture matches,
Thanks, John

 

We cross-posted and didn't see each other's comments. Tipularia gets credit for the species call.

 

Thanks Ken R. I remembered this plant from a previous post...
