Sri Lankan Boat People's Suspicious Timing

The Sri Lankan migrants that arrived illegally by boat in BC this past week have very suspicious timing. Why are they arriving now? Sri Lanka has only this year finally seen peace restored after a 26 year civil war between the Sri Lankan army and Tamil militants and terrorists. It would seem that with Sri Lanka in peace, there is no basis for cross-Pacific, human-smuggling-based, "refugee" claims.
The civil war started in 1983 with Tamils fighting against their own country out of nationalistic demands for a Tamil state. The Tamil Tigers, throughout this period, were brutal. This is the group that first invented the practice of suicide bombing. They've conscripted child soldiers to fight for them, they've fired on civilian populations, and they hid amongst civilian targets so they could claim "war crimes" against anyone who dare attack them. But this bloody war is now over. The Sri Lankan government pushed forward with a determination and brute force that while terrible and costly, resulted in the Tamil Tigers admitting defeat and peace being restored. Tamils are no longer caught in the middle of a civil war; Tamil civilians are being given welfare and support while Tamil militants are being rehabilitated. So why are these migrants here now?
They either preferred living under civil war, which is unlikely, or they were Tamil militants themselves or supporters of the terrorists. Either way, they are not needed in Canada. They broke our immigration laws and flouted our sovereignty. They may have also used human smugglers to get here. Allowing them to stay would reward such behaviour and encourage more human trafficking to occur.
News is now coming that at least one of them has laready been identified as a wanted terrorist.

The Canadian government already has a very lenient immigration system. We already allow hundreds of thousands of immigrants to settle in Canada each year legally. There is no argument for allowing illegal immigrants or migrants to successfully seek residency and citizenship. And these Tamil migrants are certainly no exception.
