The Harperites have resurrected the unjust, immoral, and, according to international treaties to which Canada is a signatory, illegal bill formerly known as C-11.
Jason Kenney doesn't want so much riff-raff allowed into Canada. So first he let positions on the Immigration and Refugee Board go vacant, so there weren't enough decision-makers to hear cases, thereby creating a backlog. Then he uses the backlog to say there are too many claimants.
The IRB is under political pressure to reject certain types of cases. Kenney then uses those rejections to "prove" that claimants from certain countries are "bogus" refugees and no review of their claims is needed.
When the minority Conservative government tried to rush this bill into law without debate in 2010, the NDP fought back, and after enough pressure was applied, the Liberals grew a (temporary) spine.* Amendments were added protecting the most vulnerable refugee claimants. Now the Harper GovernmentTM wants to use its majority power to get their anti-refugee, anti-human wish list into law.
Rather than re-write what I've already written, I will quote myself, and more importantly, Amnesty International, the Canadian Council for Refugees, Refugee Lawyers Association, and former immigration ministers, from the earlier fight in 2010. I hope you'll go and at least skim some of these links.

* Not really. Liberal Immigration critic Maurizio Bevilacqua, allegedly promised a Conservative endorsement of his forthcoming campaign in the city of Vaughn, did the Tories' work for them, playing sock-puppet for Jason Kenney. By all reports, then- Liberal Leader Michael Ignatieff was ready to side with Bevilacqua, until a revolt from his own caucus forced his hand.
