The Canadian manufacturing sector that is exporting to the rest of the world is very concentrated in the Quebec-Windsor corridor. The rest of the manufacturing sector in Canada is intimately related to the natural resource industry. Consequently, it is supplying inputs to the natural resource industry and will generally benefit from an oil boom.
However, the province that will be the least able to export manufacturing goods to the rest of the world will be Alberta. It is extremely hard to export goods that are not related to the oil and gas sector in Alberta because the cost of production there is so high.
