Daily Oil Bulletin reports Canada's total proved oil and liquids reserves continued to climb in 2010, rising to just under 22bn barrels, up 6.6% from year end 2009. About 77% of the booked reserves came from Alberta's oil sands. The news comes as Canada’s oil sands are coming under increased scrutiny: the Vancouver Sun reported on Monday that the federal government deliberately excluded data indicating a 20% increase in annual pollution from the oil sands industry in a report to the UN. Last week during Congressional hearings it was revealed that the oils sands are poised to become the number one source of crude for the US.
