How to work as a CNA or LPN in Canada?

Hi, I've stayed in the States for a very long time. I know to be a Certified Nurse Aid in the States, you need to attend a CNA class. The class is short and jobs are plentiful. But I am not sure about how things are in Canada.

Can anybody tell me if there is similar type of position in Canada? If yes, what it is called? And how long the training would be? Would it be difficult to find such a job?

I think it would be nice to do such a job while I am in nursing school (If I am lucky and could get into a school at the border), to get health-care experience and get money to pay the bills.
