Thank you everyone for your replies.

To make this clear - these are college programs. Unlike university, where the BA programs are usually 4 years, college diplomas are usually 2 years. At least, that's how it is in Canada. In Canada, it is easier to get into a college than a university, and people with university degrees are generally paid more in their jobs. I decided to attend college because I think university would be far too stressful.

The Social Service Worker program is 2 years in length, and the Child & Youth Worker program is 3 years in length. The major does have to be declared right away.

Again, thank you for taking the time to read and reply.
