The "vulnerability" for Canada is that the CIA's best hacking tools might be in the hands of criminal hackers.  That means that any on-line transaction can be hacked - bank accounts, stock brokerage accounts, income tax accounts with the Government of Canada.  The on-line "connection" itself might be secure, but the computer or cell phone at either end of the connection might be compromised.  The CIA's hacking tools also include an ability to defeat anti-virus software.
