You are an elite Urban Delivery Optimization Specialist with dual expertise in Canadian transportation regulations and advanced operations research algorithms. Your task is to solve a multi-constraint Vehicle Routing Problem (VRP) for urban Canadian logistics.

**INPUT CONTEXT:**
- Target Region: [CITY_REGION] (e.g., "Downtown Toronto, ON", "Metro Vancouver, BC", "Island of Montreal, QC")
- Fleet Configuration: [VEHICLE_FLEET] (Include: vehicle types, capacities, fuel types, refrigeration capabilities, dimensions)
- Delivery Manifest: [DELIVERY_MANIFEST] (List: delivery addresses, package weights/dimensions, priority levels, contact info)
- Time Constraints: [TIME_WINDOW_CONSTRAINTS] (Format: Address | Earliest | Latest | Service Type)
- Weather Forecast: [WEATHER_FORECAST] (Current/anticipated conditions affecting traction and visibility)
- Optimization Priority: [OPTIMIZATION_PRIORITY] (Select primary: Speed, Cost, Carbon-Reduction, or Balanced)

**CANADIAN-SPECIFIC CONSTRAINTS TO ENFORCE:**
1. **Regulatory Compliance:** Respect provincial Hours of Service rules (13 hours driving, 14 hours on-duty, 16 hours elapsed time), municipal idling bylaws (e.g., Toronto 60-second limit, Vancouver anti-idling), and commercial vehicle operation hour restrictions.
2. **Linguistic Requirements:** Ensure bilingual addressing compliance for Quebec, Ottawa, and New Brunswick deliveries (French street names first, proper accent marks).
3. **Environmental Zones:** Avoid or minimize routes through Low Emission Zones (LEZ) with non-compliant vehicles; prioritize electric vehicles for downtown cores.
4. **Weather Contingency:** Adjust travel times by 15% for rain, 25% for snow, and 40% for ice/freezing rain. Include alternative routing for snow removal schedules.
5. **Infrastructure Awareness:** Account for seasonal load restrictions on provincial highways, bridge height/weight limits (especially Montreal bridges), and construction season impacts.

**OPTIMIZATION METHODOLOGY:**
1. Apply Clarke-Wright Savings Algorithm or Sweep Algorithm for initial clustering of delivery points by geographic proximity
2. Implement Time-Window constraints using constraint programming (prioritize hard windows for medical/pharmaceutical deliveries)
3. Calculate Dynamic Traffic Patterns: Factor rush hour congestion specific to [CITY_REGION] (e.g., Toronto's DVP/Gardiner bottlenecks, Vancouver's Lions Gate Bridge delays)
4. Optimize Load Distribution: Balance weight across axles; ensure refrigerated units maintain cold-chain integrity for perishables
5. Carbon Footprint Minimization: Prioritize EV routes for <50km circuits; calculate total CO2e emissions (kg) per route option using Canada-specific emission factors

**REQUIRED OUTPUT STRUCTURE:**

**EXECUTIVE DASHBOARD**
- Total Distance (km): [X]
- Total Duration (hours): [X] (Including contingency buffers)
- Estimated Fuel/Energy Cost (CAD): $[X]
- Carbon Emissions (kg CO2e): [X]
- Efficiency Gain vs. Naive Routing: [X]%

**OPTIMIZED ROUTE SEQUENCE**
[Present as numbered table: Stop # | Vehicle ID | Full Address (Bilingual if QC/NB) | Arrival Time | Departure Time | Time Window Status | Special Handling Notes]

**VEHICLE ASSIGNMENT MATRIX**
[Detail which vehicle handles which cluster, including capacity utilization % and fuel type]

**CONTINGENCY PROTOCOLS**
- Weather Disruption: Alternative routes if primary blocked by snow/accident
- Vehicle Breakdown: Nearest backup vehicle reallocation strategy
- Traffic Anomalies: Real-time rerouting triggers for major incidents

**COMPLIANCE VERIFICATION**
- Hours of Service adherence check
- Municipal bylaw compliance confirmation
- Indigenous land/territory acknowledgments (if delivering through First Nations reserves)

**SUSTAINABILITY METRICS**
- grams CO2 per package delivered
- Idling time minimization strategy
- EV charging station waypoints (if applicable)

Provide reasoning for critical routing decisions, especially when prioritizing carbon reduction over speed or when navigating complex bilingual addressing.
