PART I
DEVELOPMENT OF CANADIAN ROUTING SYSTEMS
1. General ^
1.1 The purpose of this publication is to establish national standards for planning,
developing, establishing, amending and revoking routing systems in waters under Canadian
jurisdiction.
1.2 When a routing system is proposed, amended, revoked or has its voluntary/compulsory
status changed there must be thorough regional and national consultation between the Coast
Guard ship routing planners, the marine industry and other interested parties.
1.3 Interested parties at the national level are those organizations and persons who
are on the circulation list of the Canadian Coast Guard Marine Advisory Council (CMAC).
Regional CMAC circulation lists will describe local interested parties.
1.4 Consultations shall be well documented and interested parties kept fully informed
of the developments and the results of the consultation whether or not they participate.
1.5 The Director General Ship Safety of the Coast Guard (Director General) has the
responsibility for routing systems and must be advised as soon as possible whenever any
routing proposal is under consideration. The Director General will inform the Canadian
Hydrographic Service (CHS) so that charting action can be planned.
1.6 Navigation safety and pollution prevention must not be compromised when reaching a
decision between interested parties. Experience has shown that no routing system can
entirely satisfy all parties because of their divergent concerns.
2. Regional level ^
2.1 In general, routing proposals will be initiated at the regional level and in
accordance with specific regional consultative procedures. In some cases routing proposals
will be initiated at the national level.
2.2 A regionally endorsed CMAC routing proposal will be forwarded to the Director
General where it will be reviewed for compliance with these routing standards and Coast
Guard policy. The Director General will forward the proposed routing system to CHS for
review in accordance with their charting standards and those of the International
Hydrographic Organization (IHO).
2.3 Routing proposals which do not meet these standards and policy will be returned to
the region for amendments. Simple amendments may be made by the Director General in
consultation with regional Coast Guard representatives where time would not permit a full
review at the regional level.
3. National level ^
3.1 The Director General will table an accepted regionally endorsed routing proposal at
the next CMAC meeting for national endorsement.
3.2 Following national endorsement the Director General will forward the routing
proposal to CHS for charting action, and will prepare a series of notices to mariners.
3.3 The first notice to mariners will be promulgated when the charts or chart patches
showing the routing system are available to mariners. This first notice will give three
months warning of the coming into force of the routing system. The second notice will be
promulgated as closely as possible to the date that the routing system comes into force.
This second notice is a reminder and final notice.
3.4 No routing system will come into force until six months following its endorsement
by the national CMAC meeting, except in cases of emergency.
3.5 These implementation procedures may be by-passed in emergency situations and
traffic routed and rerouted, or a routing system temporarily established, amended or
revoked for navigational safety and pollution prevention purposes. If emergency measures
are required they should be brought to the attention of the interested parties as soon as
possible.
3.6 The coordinated universal time (UTC) and the local time of the coming into force of
routing systems will be promulgated in notices to mariners. Generally, noon local time
will be used.
4. Voluntary and compulsory routing systems ^
4.1 Routing systems will be reviewed at a regional and national CMAC meeting after an
initial period of user evaluation. If a measure of agreement is reached that navigation
safety and pollution prevention is enhanced by the system, and no technical objections are
established on navigation safety grounds, then the routing system will be made mandatory
pursuant to the Collision Regulations and promulgated in the Annual Edition of Notices to
Mariners.
4.2 The period of user evaluation will vary according to the complexity of the routing
system but it should never be less than one year.
4.3 A notice to mariners will be prepared by the Director General when a routing system
is changed from a voluntary to a compulsory system and vice versa. This notice will give
mariners three months notice of a change in status.
5. Controlled and/or prohibited areas ^
5.1 Controlled and/or prohibited areas are routing systems and are dealt with by these
standards.
6. Annual Edition of Notices to Mariners ^
6.1 The Canadian Annual Edition of Notices to Mariners describes all routing systems
adopted by the International Maritime Organization (IMO), and all Canadian domestic
routing systems. This Annual Edition also describes whether a routing system is voluntary
or compulsory. The Annual Edition is kept up-to-date by notices to mariners and notices to
shipping.
