I'm rather stunned that the people helping Snowdon were not local Hong Kong people, but were from the Philippines and Sri Lanka. Not quite surprised that they were clients of Tibbo. Tibbo seemed to have convinced the asylum shoppers to help Snowdon, and having failed to get asylum in Hong Kong, is using the Snowdon connection to try to get to Canada. If Canada lets them on its soil, they will have so many appeals processes that they might as well get PR status, and then they definitely won't regret helping Snowdon. 

However, as people who would be accused of helping a traitorous felon, Canada is not safe for them, as the U.S. will request they be extradited to stand trial, using their asylum application against them.
