Usually, when an individual is arrested, he is indeed taken before a justice of the peace. If the Crown is against releasing him, a bail hearing must be held. With respect to language the hearing is held in, I will defer to my colleague.
However, there are two possibilities with respect to bail. A justice may decide that one of the conditions of release is paying a certain amount of money. This is then set out in the bail conditions, and the individual is held in detention until the conditions are met. Once all conditions are satisfied, and bail is paid in cash, the individual is released.
