The job search should be easy.  Two job search sites I have used to find co-op jobs are Simplyhired.ca and Indeed.ca. These sites are the Google of job search. Indeed and Simplyhired are so good because:

– jobs are aggregated from Monster, Workopolis, Careerbuilder and more job sites
– jobs are also pulled from company career pages
– all the jobs on the internet are on one spot

An example search for co-op jobs in Toronto found NEW HP , Telus , RBC and IBM co-op positons. sweet.

I liked the job search engines that powered Simplyhired and Indeed so much, I used both job search engines for Buddingup.com to power the Canadian and U.S. job search.
