$150B (Canadian, not that there is much difference today) is a lot. That is projects in construction now and in different stages of design and permitting going out for the next decade.

Oil sands now account for 39 per cent of Canada’s total oil production at approximately one million barrels per day. By 2020, production will grow to four million barrels per day.
Total Canadian production is projected to increase from the current 2.5 million barrels per day to reach 4.9 million barrels per day (b/d) by 2020.
Wow ! That is a huge jump since the 2006 report I read. From a new total of 1.7M by 2016 to 4M by 2020 !
