Better look at the figures, which are readily available. What CA-SK contract?

Most Sask. natural gas is sold to marketeers and brokers.
2006 figures:
3.6 billion cubic meters to marketers or brokers
2.1 billion cubic meters to SaskEnergy
1.2 billion cubic metres in direct sales to industrial and
   commercial users in Sask.
233 million cubic metres in direct sales to out-of-province buyers
   (only 3.3%)

"Producers have the choice of selling to SaskEnergy [prov. gas utility, which is going into global opportunities], to natural gas marketers or brokers, to direct sales in Sask. or to markets in Eastern Canada and the United States."
This last amount is small.
Figures from www.ir.gov.sk.ca ("Natural Gas in Saskatchewan")

California imports 85% of its natural gas, 64% from other states and 24% from Canada. The latter comes through pipeline systems and includes gas from all western Canadian provinces. Within ten years, gas from the Canadian Beaufort and Alaskan North Slope also will be available.
Alberta and British Columbia both produce more gas than Saskatchewan, and contribute most to pipeline systems.

SaskEnergy and Nova Gas (pipeline operated with TransCanada) are looking for investments; they are expanding their interests in Chile (SaskEnergy Chilean Holdings), where they have the major interest in the trans-Andean pipeline carrying Argentine gas to Chile. SaskEnergy also operates a major pipeline in Mexico.
