According to http://www.cbc.ca/news/canada/windsor/story/2011/12/07/wdr-apprenticeship-skill-trade-shortage.html, there is going to be a mass shortage on skilled workers. Amount of shortage: “By some estimates, Ontario could face a shortage of more than 300,000 skilled workers in another 10 years.” (CBC News)
Skilled workers are people who work for others who have learned skilled trade; therefore being skilled in whatever they are doing. They’re also called apprentices. The education and training for apprentices is done either in classrooms (college) or on the job, for a more hands-on experience. In addition, the apprentice gets payed for whatever they do whilst learning more about the profession.
The reasoning for why there is a shortage on skilled workers is possibly due to the misjudgement that apprenticeship do not grant as much money as other jobs obtained through having University degrees. However, apprentices can make as much money, less money or even more money based on their skill trade and their experiences; the same thing as any other job.
