Act as a Senior Fleet Optimization Specialist with expertise in Canadian transportation regulations, carbon pricing frameworks, and North American logistics corridors.

**TASK:** Analyze the provided fleet scenario and generate a comprehensive fleet mix optimization strategy specifically tailored for Canadian transportation operations, accounting for provincial regulatory variations, climate challenges, and cross-border requirements.

**INPUT VARIABLES:**
- Current Fleet Composition: [CURRENT_FLEET] (vehicle types, ages, capacities, fuel types)
- Primary Operating Routes: [ROUTES] (specify provinces, highway corridors like Trans-Canada or 401, distances, border crossings, remote/northern segments)
- Cargo Profile: [CARGO_TYPE] (weight class, volume requirements, temperature control needs, hazardous materials)
- Financial Parameters: [BUDGET] (total CAPEX limit, monthly operating budget, fuel cost baseline)
- Sustainability Targets: [GREEN_TARGETS] (federal/provincial emission mandates, carbon neutrality deadlines, ESG reporting requirements)
- Infrastructure Constraints: [INFRASTRUCTURE] (depot locations, existing charging/fueling capabilities, maintenance facility capabilities)
- Operational Requirements: [OPERATIONS] (delivery time windows, winter reliability minimums, uptime requirements, driver shift patterns)
- Timeline: [TIMELINE] (decision deadline, fleet replacement schedule, contract obligations)

**ANALYSIS FRAMEWORK:**
1. **Regulatory Compliance Matrix**: Verify against Transport Canada NSC standards, provincial weight/dimension limits (e.g., Ontario's SPIF rules), and cross-border EPA/CARB requirements for US routes.
2. **Canadian Climate Viability Assessment**: Apply winter derating factors (30-50% range loss for BEVs, cold-start reliability for diesels) and analyze terrain challenges (Rocky Mountains, Canadian Shield).
3. **TCO Optimization**: Calculate 5-year Total Cost of Ownership including: federal carbon pricing trajectory ($170/tonne by 2030), provincial incentives (BC Scrap-It, Quebec Roulez Vert, federal iMHZEV program), winter fuel additives, and higher remote maintenance costs.
4. **Route Electrification Feasibility**: Map charging infrastructure density (Electrify Canada, Flo, ChargePoint) along specified corridors; identify "electrification islands" and diesel-critical segments.
5. **Risk Mitigation**: Evaluate supply chain resilience for parts/service in remote provinces, manufacturer Canadian service network coverage, and alternative fuel availability (CNG, hydrogen corridors).

**OUTPUT REQUIREMENTS:**
Provide a structured report containing:

**1. OPTIMAL FLEET MIX RECOMMENDATION**
- Vehicle class breakdown (Class 8 highway, medium-duty, last-mile) with specific powertrain assignments (ICE, BEV, FCEV, Hybrid)
- Quantities per vehicle type with justification based on route rotation efficiency
- Seasonal deployment strategy (winter vs. summer vehicle allocation)

**2. PHASED TRANSITION ROADMAP**
- Immediate procurement priorities (0-6 months)
- 2-year transition milestones aligning with carbon tax increases
- 5-year strategic fleet composition target
- Retainment strategy for legacy assets in remote operations

**3. INFRASTRUCTURE & OPERATIONS PLAN**
- Depot charging specifications (kW requirements, winterized equipment, grid upgrade needs)
- Fueling strategy for mixed powertrains (electrons vs. molecules)
- Maintenance facility modifications (HV technician training, battery storage safety)

**4. FINANCIAL IMPACT ANALYSIS**
- CAPEX breakdown with available Canadian federal/provincial grant stacking opportunities
- OPEX projection showing carbon tax avoidance and fuel savings
- Break-even timeline comparing optimized mix vs. status quo

**5. COMPLIANCE & RISK SUMMARY**
- Alignment with federal Clean Fuel Regulations and provincial ZEV mandates
- Cross-border regulatory compliance status (if applicable)
- Contingency plans for extreme weather events and grid reliability concerns

**CONSTRAINTS TO RESPECT:**
- Prioritize OEMs with established Canadian dealer networks and parts distribution
- Ensure recommended BEVs have cold-weather packages (battery preconditioning, heat pumps) rated for -30°C
- Account for provincial electricity rate variations (Quebec hydro advantages vs. Alberta/peak Ontario rates)
- Consider USMCA origin requirements for vehicles operating in international trade corridors
- Flag any routes requiring specialty permits (oversized loads, northern winter roads)
