Divisive terror law losing traction

Can we trust secret evidence, often borrowed from foreign countries, to throw people out of Canada?

Colin Freeze explains the security certificates:

… federal ministers sign off on a certificate after viewing secret CSIS information, which allows officials to immediately jail, and eventually deport, a non-citizen.

The “intelligence” used to do this is disclosed to judges but never fully revealed to the accused, drawn as it usually is from secret agents and wiretaps, sometimes placed within Canada but also frequently “loaned” from foreign governments on condition that the provenance be kept secret.
