Thanks for the map. How many of these pipelines carry "tar sand oil"? There is a difference in crude oil and tar sand oil.

Looks like it won't matter anyway, another company Enbridge will deliver it.

“Tar Sand Oil”???

Do you mean Bitumen?

Most of the Canadian Petroleum production is from the oil sands so most if our imports from them are the same.

Can you tell me how one petroleum is different from the other in terms of the pipeline issue?
