There are a lot of pro-life organizations whose function is to do this, but CCBR's tactics are rather less conventional (and more controversial): our main campaigns incorporate the use of abortion victim photography, with the reasoning that, historically, all the major movements against human rights abuses used images of the victims in order to expose the injustice.
Abortion is also unique in that, unlike other human rights abuses, the victims have no voice of their own. By showing their broken bodies, we are enabling them to speak for themselves, to exist as testament to the unspeakable injustice that's been committed against them. A picture is worth a thousand words, and sometimes the only way to convey the horrible reality of indescribable injustice is to show it.
When it comes to ending abortion, CCBR's guiding principle is effectiveness: if something we're doing doesn't work, then we change it. The reason we continue to do what we do with the abortion victim photos is that we have seen, and continue to see, significant results. Humans are visual creatures that respond strongly to visual evidence, and as someone who's worked CCBR's front lines I can attest to the fact that what we do is changing the way the public views abortion. By showing these images and engaging in meaningful conversations with members of the public, we're making a huge difference in the way people perceive the issue of abortion. I haven't had any conversations yet where someone had a total one-eighty about abortion, but my coworkers have had many, many people who have completely changed their opinions about abortion based on their encounter with CCBR's campaigns.
So, that's the basic nitty-gritty of why we do what we do. I'm happy to answer any questions anyone has, though I also recommend you check out CCBR's website, since the resources explain anything you could ever ask much better than I could: http://www.unmaskingchoice.ca/
On a more personal note: I absolutely love my job. I've made fast friends with all my coworkers, who are all friendly, intelligent people, and any time not spent working to save babies is spent trying to make each other laugh (see office whiteboard below).
Not only that, but through our many social gatherings and various visits from guest instructors, I've become acquainted with a great many people who are crucial to Canada's pro-life movement, and I hope to become acquainted with even more of them as the summer progresses. 
Basically, I feel like I'm spending the summer with my heroes.
