Victims don't typically appear at a bail hearing, so they wouldn't necessarily be present. It is possible, but it's uncommon, because a bail hearing takes place within 24 hours. It's sort of a cooling-off period to separate the two parties, so the victims don't usually show up.
If the Crown feels that there's a sensitive or delicate issue with respect to a victim's discussing their security needs in court, the Crown can always ask to go into chambers with the lawyer for the accused and the judge to speak about it privately. That is an option, but it wouldn't necessarily be an option for a self-represented accused.
