Bail is heard in provincial courts with provincially appointed Justices of the Peace, or very occasionally a judge for a bail review. Remand custody happens in provincial jails. The former frequently cite the overcrowding and terrible conditions of the latter as a reason to release on bail.
Crimes that are prosecuted summarily, which is most of them, are tried in lower level provincial courts. These courts are horribly backlogged and now routinely double or even triple book judges and court rooms. This causes significant delays in trials, resulting in lots of cases being dismissed per Jordan. It also means that crowns are heavily pressured to make sweetheart deals to keep matters out of court.
Any significant improvement in our criminal justice system needs to start in the provincial courts and provincial jails. Neither is something that will take Parliament legislating. I suppose a Parliamentary committee could do a study and write a report saying what I just said but that would just be repeating what everyone working in the system knows anyway.
