For work, be sure to see the resume sample on our Essential Guides.
Review our networking guide there too and check I/CAN jobs regularly (although this is a small site, there are a few gems that get posted here).
Also, note that our website has all of the major job sites in Canada listed by province. We frequently post-employment tips on our FB page: Irish Canadian Immigration Centre.
