An apprenticeship is when someone is instructed (usually for a limited period of time) by a master of a certain craft or trade with the goal of becoming a certified tradesperson. For some students, the summer could be the perfect time to begin training. Some apprentices are even compensated for their work. When seeking an apprenticeship, it is important to decide which province or territory you plan to work in, because the requirements for obtaining trade certification may vary across the country. To officiate an apprenticeship, you must have what is called an Apprenticeship Agreement signed by the employer, the apprentice and apprenticeship office of the province/territory where the training will take place. Apprenticeships are primarily comprised of on-the-job training, but some in-class time may also be required. After a certain number of years as an apprentice (this varies by trade) you will have to take a trade exam administered by your home province or territory. Upon passing, you will be a fully-qualified tradesperson in your region.
