The Canadian manufacturing sector continued to recover in 2011 following the economic downturn of 2009. Higher sales reflected greater domestic and foreign demand for Canadian manufactured products. Manufacturing sales advanced 7.8% in 2011 to $571.2 billion. Manufacturers in 14 out of 21 industries reported higher sales in 2011 compared to 2010. Gains in the petroleum and coal products industry contributed greatly to the rise in manufacturing sales. Primary metals, transportation and machinery manufacturers also reported higher sales and contributed to the overall increase. Sales in machinery were at a record high in 2011. Over one-third of the sales advance in machinery was reported in mining and oil and gas field equipment machinery. Increased capital expenditures in the conventional and non-conventional oil and gas extraction sector in the last few years have fostered growth in this industry.
