Canada produced a total of about 6.05 billion GJ of natural gas in 2010.  Although most of this supply was conventional, it's expected that the production of unconventionals such as offshore gas, shale gas and coalbed methane (CBM) will predominate in the future. They're called "unconventional" because they're produced or extracted using techniques other than the traditional gas well method.
British Columbia is the second largest producer in Canada.  Yukon and the Northwest Territories also produce natural gas. See the region's production statistics here.
We export about half of our production to the US. From an American perspective, Canada represents their single largest source of natural gas imports (90% in 2008).
In 2010, production and processing consumed 62,545,390 GJ and emitted 10,186,270 GHG tonnes.
