In order to find the answer to this question, you can go to this website, which is provided by the government of British Columbia. The information that you need is there.
The site shows you that the percentage of the work force that is employed in each of these industries is as follows:
- Construction: 9.5% of all workers
- Manufacturing: 8.1%
- Agriculture: 1.5%
- Forestry and logging: .8%
The site also gives the percentages of the provincial GDP that are produced by each of these industries. They are as follows:
- Construction: 6.2% of provincial GDP
- Manufacturing: 9.3%
- Agriculture: .7%
