of its orders, control over its own process, and its residual jurisdiction as a
court of original general jurisdiction.
[Emphasis added.]
[45] In addition to those previously recognized aspects of core jurisdiction, the
Court in the Article 35 Reference emphasized that if the superior courts are to have
the unifying effect that motivates s. 96, they must maintain a significant role in the
development of the private law:
[83]
In our view, the superior courts’ core jurisdiction presupposes a broad
subject‑matter jurisdiction whose scope corresponds, at the very least, to the
central divisions of private law to which more specific fields of law are often
attached. This can be explained by the superior courts’ historical origins and
their nature as courts of original general jurisdiction, as well as by the
principles of national unity and of the rule of law that underpin s. 96.
[84]
Historically, the English royal courts had general civil jurisdiction and
were responsible for the major developments in private law. The Canadian
superior courts, which are descended from those courts, inherited their role of
prime importance in the judicial system. At the time of Confederation, they
had jurisdiction over all important civil cases.
[85]
The paramount role given to the superior courts derives in part from
the fact that they are courts of original general jurisdiction. A court of original
general jurisdiction is the antithesis of a specialized tribunal. A specialized
tribunal draws legal conclusions based on a limited number of principles and
rules falling within its area of expertise, whereas a court of original general
jurisdiction considers and interprets many principles and general rules that
may apply in a number of fields of law. In giving the superior courts this
breadth of perspective, the framers of the Constitution intended them to
ensure the maintenance and coherent development of an actual order of
positive laws, as well as to ensure stability and predictability in private law
relationships. If the legislatures were free to diminish, by means of unlimited
transfers of jurisdiction, the superior courts’ ability to lay down the broad lines
of the case law, it would no longer be possible for these courts to perform
their constitutional role as the primary guardians of the rule of law.
[86]
This is why a general jurisdiction over private law matters must be
accompanied by a subject‑matter jurisdiction that is broad enough to
preserve the superior courts’ role in providing jurisprudential guidance on
private law. In our view, this requires significant — though not necessarily
predominant — involvement in the resolution of disputes falling under the
most fundamental branches of private law, such as property law, the law of
succession and the law of obligations. A province may assign portions or
offshoots of these fields to courts whose judges it appoints, within the
restrictions of Residential Tenancies. But if, in so doing, it limits the superior
court’s involvement significantly, then it “alters [that court’s] essence, making
it something less than a superior court”. In short, a province which takes
away an aspect of the court’s core jurisdiction contravenes s. 96 — a
provision whose purpose lies in the “maintenance of the rule of law through
