Where help comes from

In the first days, road, rail, air and marine transport are disrupted and “existing supply chains will be inoperable”. Areas are isolated, unreachable by road because of landslides, liquefaction and collapsed bridges, and cut off further by damage to airports and marine ports. Inside that area, local capacity to respond “will be limited and delayed”. [1] What that does to the crossings and the terminals is on transportation and large infrastructure.

Leaving is not the plan: “damage to transportation routes and the prioritization of essential personnel and supplies make mass evacuation impossible, and the public is directed to shelter in place.” [2]

Disaster Response Routes are corridors kept open for emergency vehicles, and once they are activated the public is told to get off them as soon as possible. [3] They are roads to leave, not roads to leave on. Getting around covers the signs.

The province’s general emergency plan, the All-Hazard Plan, works from the bottom up. The province’s role under it is supplementary: it “will coordinate available resources to provide emergency response assistance that supplements but does not substitute for community resources”, and the first move belongs to the local authority. The plan allows that order to be turned around and treats it as the exception: a situation at the international or national level “may reverse or otherwise change the normal ‘bottom-up’ approach to response”. [4]

The earthquake strategy makes the exception the rule. In a major earthquake the province “will stand up response measures outlined within this strategy and proactively deploy resources into the impact area”. [1] Nobody has to ask first. The general plan has not been amended since 2016. [4]

Agencies inside the impact area are reduced or delayed, while “those outside the impact area will be largely unaffected and functional”. The staging follows: “Provincial staging areas are located outside the impact area and will be used to organize, prioritize, and disseminate critical resources.” [1]

That is a planning assumption: what a province decides to plan against. It is not a measured finding about how help would arrive.

In the shallow crustal magnitude 7.0, the outside is the rest of the province

The province’s crustal planning scenario is a magnitude 7.0 beneath the Strait of Georgia, and its damage is concentrated and local. [1] The impact area is the Lower Mainland. The rest of British Columbia, Alberta and the American Pacific Northwest are outside it, which is the case the staging plan is built for. Help still has to travel over damaged roads, and the first response is still the local one. [4]

In the Cascadia magnitude 9.0, the province says the United States may be unable to help

From the Cascadia appendix of the province’s earthquake response strategy, on a rupture of the Cascadia subduction zone, the offshore fault that runs the length of the coast:

The province’s regional and central coordination centres, the PREOC and the PECC, decide what provincial support goes where. [5] In this scenario both are “compromised due to damage to facilities and impacts on staff” and have to work from alternate locations. [2]

The word the province uses is delayed: “resources from other parts of B.C., other provinces and the U.S. are delayed due to widespread transportation and communication disruptions.” [2] The plan is that a community holds on until help arrives. [1] The two scenarios sit side by side.

In June 2016 the province ran Exercise Coastal Response, its first full-scale earthquake and tsunami exercise, with about 800 participants from 65 organisations. [6] Two of its objectives were about help from outside British Columbia, and neither was tested. Activating the Pacific Northwest Emergency Management Arrangement: “(Not tested due to concurrent Exercise Cascadia Rising)”. Requesting activation of Alberta’s earthquake plan for British Columbia: “(Not tested due to real-world constraints)”. [6]

British Columbia could not exercise its cross-border arrangement because its cross-border partners were exercising the same earthquake. It publishes summaries of these exercises. Full after-action reports are not published. [7]

The All-Hazard Plan is dated 4 November 2012 and was last amended on 22 June 2016. It promises that it “will be reviewed and updated by EMBC every four years”, naming an agency that is now the Ministry of Emergency Management and Climate Readiness, which publishes the earthquake response strategy. [4] [1]

The plan is made under the Emergency Program Act. [4] The ministry’s own legislation page states that the Emergency and Disaster Management Act “replaced the Emergency Program Act in 2023”, and announces no successor to the framework or to the 2016 guide that sets out how a response is organised. [9] [5] The All-Hazard Plan was still the province’s published plan on 23 December 2025, the date the provincial emergency plans page was last updated. [10]
