8.1Water, the baseline system chapter
Canada’s water system is defined by abundance in total and scarcity where people, farms and power plants are. The binding stresses at baseline are drought in the West, flood in cities and corridors, and service gaps in remote communities.
| Component | State | Evidence | Status |
|---|---|---|---|
| Supply and storage | large but seasonal; snowpack and glaciers drive western summer flows | 85 | Reported |
| Drought | recurrent on the Prairies and in southern British Columbia; 2021 is the reference year | 20 | Reported |
| Flood | urban pluvial and riverine flooding is a leading driver of insured and uninsured losses | 422 | Inferred |
| Service access | long-term drinking-water advisories persist on some First Nations systems | 28 | Reported |
| Energy link | hydro dominance makes low water an electricity event | 9 | Inferred |
Couplings into other systems
- WAT → ENE hydro output in dry years
- WAT → FOO irrigation and rain-fed yields
- WAT → HLT drinking water and sanitation
- BIO → WAT wetland and forest regulation
Evidence to bind in 2027
- basin-scale water stress under multi-year drought
- groundwater levels and recharge
- municipal supply resilience in dry years
8.2Energy, the baseline system chapter
A low-emitting electricity system sits beside an emissions-intensive oil and gas sector. Hydro dominance makes water the key energy risk, while heat and cold set peak demand.
| Component | State | Evidence | Status |
|---|---|---|---|
| Generation mix | about 60% hydro, with nuclear concentrated in Ontario | 9 | Reported |
| Emissions | oil and gas the largest emitting sector; methane at a record low | 1 | Reported |
| Reliability | peak demand in heat and cold; interties and trade balance provinces | 15 | Inferred |
| Dry-year exposure | lower hydro output raises imports and cuts exports | 9 | Inferred |
| Transition | electrification raises demand; long-run projections in Canada’s Energy Future | 15 | Reported |
Couplings into other systems
- WAT → ENE hydro supply
- ENE → FOO fuel, fertiliser and cold chain
- ENE → HLT power and cooling for care
- AIC → ENE new data-centre load
Evidence to bind in 2027
- monthly hydro storage and import dependence
- peak-demand margins under compound heat
- data-centre load growth by province
8.3Food and agrifood, the baseline system chapter
Canada is a major exporter of grains, oilseeds and potash, and its yields swing with Prairie weather. Food security at home depends on access and affordability as much as on production.
| Component | State | Evidence | Status |
|---|---|---|---|
| Production | grains, oilseeds and pulses on the Prairies; diverse production in the East | 20 | Reported |
| Drought sensitivity | 2021 heat and drought cut canola by about a third, and wheat by more | 20 | Reported |
| Inputs | fertiliser, fuel and potash; Canada is a leading potash producer | 30 | Reported |
| Logistics | export grain moves by rail to west-coast and Great Lakes ports | 23 | Inferred |
| Access | household food access and affordability not yet bound at baseline | , | Expert input |
Couplings into other systems
- WAT → FOO rain-fed and irrigated yields
- ENE → FOO inputs and cold chain
- FOO → TRD export volumes
- BIO → FOO pollination and soils
Evidence to bind in 2027
- post-2021 drought impacts by region
- household food access and affordability
- rail and port continuity in harvest season
8.4Health and One Health, the baseline system chapter
Health is an active system, not only an outcome. Heat, smoke and zoonotic spillover now load it each season; spending is high, and surge depth is not documented.
| Component | State | Evidence | Status |
|---|---|---|---|
| Spending | total health spending at 12.4% of GDP in 2024 | 21 | Reported |
| Heat | the 2021 heat dome is the deadliest weather event in Canadian history | 6 | Reported |
| Smoke | fire seasons bring weeks of smoke to distant cities | 1840 | Reported |
| One Health | H5N1 in poultry and wild birds; a domestic human case in 2024 | 27 | Reported |
| Surge capacity | not documented nationally at public-safe resolution | , | Expert input |
Couplings into other systems
- CLI → HLT heat mortality and morbidity
- BIO → HLT smoke and zoonoses
- ENE → HLT power and cooling in care settings
- FOO → HLT nutrition and food safety
Evidence to bind in 2027
- emergency surge under concurrent heat and smoke
- cooling in long-term care and housing
- One Health surveillance integration
8.5Biodiversity and ecosystems, the baseline system chapter
Canada holds vast forest, freshwater and marine ecosystems. Conservation stands at about half of the 2030 target, and fire is now the fastest-changing pressure.
| Component | State | Evidence | Status |
|---|---|---|---|
| Extent | about 9% of the world’s forests; extensive wetlands and peatlands | 31 | Reported |
| Conservation | 13.7% of land and 14.7% of marine areas, against 30% by 2030 | 713 | Reported |
| Fire | record 2023 season; seasons starting earlier and lasting longer | 1040 | Reported |
| Condition | ecosystem condition outside protected areas not yet bound | , | Expert input |
| Services | water regulation, pollination and carbon storage | 44 | Inferred |
Couplings into other systems
- BIO → WAT regulation and filtration
- BIO → FOO pollination and soils
- BIO → HLT smoke and zoonoses
- CLI → BIO fire and heat
Evidence to bind in 2027
- ecosystem condition indicators
- peatland carbon under fire
- species-at-risk trends by region
