Pipelines are by far the most effective and safest way to move it. It all depends on whether you can position that pipeline.
In the case of the Nova Scotia example, the technical and cost challenges of extending the pipeline are such that it's more cost-effective to use the CNG model. There's an economic model, which is pretty straightforward, to determine which works in which case. In the earlier example of northern Canada, a pipeline is not the appropriate strategy; to truck CNG or LNG is the appropriate strategy in that instance.
