Here is an article predicting significant decline in NG imports from Canada in the next two years.

I am not familiar with this author so I have no impression about his accuracy.  One thing he seems to do is equate his expected drop in Canadian production with a reduction in export to the US.  Is that an accurate assumption?  Has anyone seen other confirmation of such predictions?

Excerpt:

"Declines in Canadian natural gas imports to the US over the next two years will be nearly equal to halting production from America’s biggest field, the Barnett Shale. I expect that the drop in Canadian imports will push natural gas prices into the double-digits by mid-2011 if not sooner."
