Experience before nursing school in Canada.

Hello all,
I'm sorry if this has been asked before, but I've been strongly considering nursing for about a year now. I've set things up and should hopefully be entering into a program in Ontario this fall. I'm about 90% sure this is what I want, but it's hard to really know before being in it. I know in the the States they have CNAs and other entry level jobs that take a month or so to certify for. Is there any kind of similar position in Canada I could do to get some first hand exposure before nursing school, and gain some work experience that may help when looking for a job after school. I would really appreciate any suggestions as to what I could be doing now.
