O BCCLA obteve o CBSA diretrizes sobre acesso a dispositivos digitais. Infelizmente, o PDF parece ser um bitmap em vez de um texto, por isso não posso copiar e colar a partir dele sem o recurso de OCR. No entanto, alguns trechos relevantes:
Although there is no defined threshold for grounds to examine such
devices, CBSA's current policy is that such examinations should not be
conducted as a matter of routine; they may only be conducted if there
is a multiplicity of indicators that evidence of contraventions may
be found on the digital device or media.
...
CBSA officers shall only examine what is stored within the device.
Officers are not to read emails on digital devices and media unless
the information is already downloaded and has been opened (usually
marked as read).
...
In instances where access to digital devices and media are password
protected, officers are to request the password to access the device
and record it, as well as any alternate passwords provided, in their
officer notebook.
...
Passwords are not to be sought to gain access to any type of account
(including any social, professional, corporate, or user accounts),
files or information that might potentially be stored remotely or
online.
...
If a traveller refuses to provide a password to allow examination of
the digital device, media or the documents contained therein, of if
there are technical difficulties that prevent a CBSA officer from
examining the digital device or media, the device or media may be
detained by the CBSA officer under the authority of Section 101 of the
Customs Act... for examination by a CBSA expert trained on digital
forensic examinations...
...
Until further instructions are issued, CBSA officers shall not arrest
a traveller for hindering or for obstruction solely for refusing to
provide a password. Though such actions appear to be legally
supported, a restrained approach will be adopted until the matter is
settled in ongoing proceedings.
Você precisaria de um advogado para lhe dar assessoria jurídica, mas a partir de um exame superficial das diretrizes, apareceria que seria improvável que você solicitasse senhas sem um bom motivo, e que você pode se recusar a fornecê-las e não será preso por fazê-lo; no entanto, seus dispositivos podem ser confiscados e você também poderá ser impedido de entrar.
