July 2024: $1B in flood damage. 2024: $9B total losses, Canada's worst year ever. If you're in the GTA, water is now your biggest home threat. Today: risk scores by neighborhood and your defense strategy.

High-Risk GTA Zones:

• Ajax: 4.6/5 (highest risk - Duffins Creek, low-lying areas)
• Mississauga: 4.4/5 (98mm in hours during July 2024)
• Toronto: 4.3/5 (density + 100-year-old pipes)
• Brampton: 4.3/5 (flash floods near creeks)
• Vaughan: 4.2/5 (Humber River tributaries)
• Lakeshore: Oakville/Burlington (lake + drainage backup)

Why This Is Happening:

• Climate change: "100-year storms" now every 5 years
• Aging infrastructure: pipes designed 50-100 years ago
• July 2024: 1.3 billion liters sewage dumped in Lake Ontario
• Urbanization: concrete = instant runoff overwhelming systems

3 Defense Pillars:

1. Foundation Protection

• Exterior: $90-280/linear foot (membrane + drainage tile)
• Interior: $79-205/linear foot (drainage channels + sump)

2. Mechanical Systems

• Sump pump + battery backup (essential during outages)
• Backwater valve (stops sewage backup)
• City subsidy: Up to $3,400 (potentially $6,650 soon)

3. Drainage & Grading

• French drains, proper slope, gutter maintenance

ROI: $1 spent = $3-8 saved over 10 years

Emergency Protocol:

1. Safety first (electrical hazards)
2. Document immediately (photos/video)
3. Call pros fast (mold grows in 24-48 hours)
