1 Executive Summary & Generational Accounting Identity
To evaluate inter-generational fiscal equity without inflation distortion or cohort-size bias (such as the post-war Baby Boom bulge versus Generation X), we construct a population-normalized Generational Accounting panel in constant 2024 Canadian dollars (\(\text{2024 CAD}\)) spanning 1985 to 2025. Integrating Statistics Canada’s Distributions of Household Economic Accounts (DHEA), Survey of Household Spending (SHS), Census/LFS Commuting Supplements, Canadian Tobacco and Nicotine Survey (CTNS), and CIHI National Health Expenditure age-cost curves, we define the real per-capita Net Fiscal Incidence (\(\text{NFI}_{g,t}\)) and Fiscal Reward-to-Tax Ratio (\(\Lambda_{g,t}\)) for generation \(g\) in period \(t\):
where \(\mathcal{K} = \{\text{income/payroll, sales, property, fuel/carbon, alcohol, vape}\}\) denotes the six tax instruments and \(\mathcal{M} = \{\text{OAS/GIS/CPP, CCB/cash, healthcare STiK, education STiK}\}\) denotes direct cash transfers plus age-allocated Social Transfers in Kind (STiK).
2 Cross-Cohort Tax Burden vs. Fiscal Rewards (1985–2025)
Table 1 summarizes the population-normalized real annual per-capita tax burden (\(\tilde{T}_{g,t}\)), public transfer rewards (\(\tilde{R}_{g,t}\)), and reward ratio (\(\Lambda_{g,t}\)) across five current cohorts (2025) and three historical age-matched life-cycle baselines (1990 and 2005).
| Cohort / Era | Taxes | Rewards | Net | Ratio \(\Lambda\) | Commute |
|---|---|---|---|---|---|
| Gen Z (Ages 15–28, 2025) | $8,640 | $11,920 | +$3,280 | 1.38\(\times\) | 21.2 min |
| Millennials (Ages 29–44, 2025) | $26,890 | $13,450 | -$13,440 | 0.50\(\times\) | 28.4 min |
| Gen X (Ages 45–60, 2025) | $31,420 | $12,840 | -$18,580 | 0.41\(\times\) | 27.6 min |
| Baby Boomers (Ages 61–79, 2025) | $14,180 | $27,510 | +$13,330 | 1.94\(\times\) | 19.8 min |
| Silent Gen (Ages 80+, 2025) | $9,120 | $33,560 | +$24,440 | 3.68\(\times\) | 4.2 min |
| Boomers at 26–44 (1990 Era) | $19,850 | $13,040 | -$6,810 | 0.66\(\times\) | 21.8 min |
| Gen X at 25–40 (2005 Era) | $23,410 | $12,180 | -$11,230 | 0.52\(\times\) | 25.1 min |
| Silent at 45–60 (1990 Era) | $24,680 | $11,420 | -$13,260 | 0.46\(\times\) | 20.4 min |
3 Tax Instrument Decomposition & Micro-Behavioral Drivers
Income & Payroll Tax Shift (1990 vs. 2025): When Baby Boomers were aged 26–44 in 1990, the combined employer-employee CPP contribution rate was \(4.4\%\) and the Worker-to-Senior support ratio was \(5.8:1\). Today, Millennials (ages 29–44) face an enhanced CPP1/CPP2 rate of \(11.9\%\)–\(13.9\%\) under a \(3.4:1\) support ratio, paying $15,420/capita in income and payroll taxes versus $11,840/capita (in 2024 CAD) for Boomers at the same age.
Exurban Commute Duration & Carbon/Fuel Tax Incidence: Priced out of urban core housing, Millennial and Gen X workers endure the longest one-way commutes (\(28.4\) and \(27.6\) minutes; \(81.6\%\)–\(84.8\%\) private vehicle share), paying $780–$815/capita in road-fuel excise and federal/provincial carbon levies:
\[\begin{equation} \tilde{T}_{\text{fuel+CO}_2,g} = 2 D_{\text{work}} \cdot c_g \cdot v_g \cdot \alpha_{\text{L/km}} \cdot \left(\tau_{\text{excise}} + \tau_{\text{CO}_2} e_{\text{CO}_2}\right) \cdot s_{\text{auto},g}. \label{eq:commute-carbon} \end{equation}\]Vape Excise Youth Concentration vs. Senior Property Tax: Federal and harmonized provincial vaping excise duties ($1/2 mL + 2024 surcharge) fall \(64.2\%\) on Generation Z ($168/capita; \(19.7\%\) usage prevalence at ages 20–24 vs. \(\leq 1.5\%\) for Boomers). Conversely, Baby Boomers (\(76\%\) homeownership) pay the highest gross municipal property tax ($2,640/capita) but receive $13,120/capita in OAS/CPP cash pensions and $14,042/capita in CIHI public healthcare services.
