Few hardware based encryption systems are government-intrusion proof and this includes RIM.
RIM servers are scattered around the world, not all traffic is routed through RIM Canada. The ever nosey Canadian Government's Communications Security Establishment Canada performs some functions as does the GCHQ. They have an interesting document here: < http://www.cse-cst.gc.ca/its-sti/publications/itsb-bsti/itsb57-eng.html>.
Note the following extract: "Although PIN-to-PIN messages are encrypted using Triple-DES, the key used is a global cryptographic “key” that is common to every BlackBerry device all over the world. This means any BlackBerry device can potentially decrypt all PIN-to-PIN messages sent by any other BlackBerry device, if the messages can be intercepted and the destination PIN spoofed. Further, unfriendly third parties who know the key could potentially use it to decrypt messages captured over the air. Note that the “BlackBerry Solution Security Technical Overview” document [****] published by RIM specifically advises users to “consider PIN messages as scrambled, not encrypted”. "
[****] BlackBerry Enterprise Solution: Security Technical Overview, for BlackBerry Enterprise Server Version 4.1 Service Pack 5 and BlackBerry Device Software Version 4.5, Document Part #17930884 Version 2, Research-In-Motion, 2008. < http://docs.blackberry.com/en/admin/deliverables/3317/BB_Ent_Soln_Security_4.1.5_STO.pdf >
In other words RIM can, and does, provide the means to monitor in-country traffic.
