Post your resume on monster.ca, workopolis.com, and linkedin.com. Keep in mind that employers and recruiters search these sites electronically, so make sure you include all the keywords, software and skills that they will use when looking for someone for a job you want. Look at job ads to figure out what those words are. Set up an alert from Monster to get emails with new job postings. Every few weeks, update your resume on Monster and Workopolis (updates trigger interest).
On LinkedIn, get three people to give you recommendations. (Apparently it is not uncommon for employers and recruiters to filter searches to people with at least three recommendations.)
Register with the major recruitment companies in your town and in any town you would be willing to work in. Try to make an appointment to meet with one of their recruiters and treat it like a job interview. Ask them for advice about your resume. I am registered with a bunch, including Procom, Ian Martin, ProVision... I can't remember them all. Here's a site that has links to some recruiters and similar companies: KW Jobs, but there are loads out there.
Set up a job alert at indeed.ca. Before my recent job switch, I got a daily alert from indeed.ca of all writer jobs in Waterloo Region and Toronto. Indeed is a little different from other sites because it trawls through corporate careers pages finding job postings, so catches some that aren't posted on Monster or wherever.
Bookmark sites that have job postings you're interested in, such as Southwestern Ontario STC, Data Shaping, Charity Village and Mobile Dev Jobs.
If you're interested in living in the US, two must-see sites are dice.com and the US STC job bank.
There are millions of online sources of advice, but here's a good one: STC job bootcamp. My main piece of advice is to have a friend revise your resume. The biggest mistake on resumes is that people don't sell themselves sufficiently: an objective person can point out where you need to beef up your sales pitch.
The University of Waterloo careers department has a boffo career consulting service. If you are a UW alumna, you get three free sessions; otherwise there's a modest fee. It is well, well worth it. You can sign up on this site, which also has lots of great info: UW career action.
I wish everyone well.
