Pricing concrete repair and leveling locally is easiest to judge from real line items. Spalling repair - moderate (steps/porch surface) runs $1,000–$1,500 per job, per Toronto Concrete Repairs, and foundation crack injection - polyurethane (leak-stopping) runs $600–$1,000 per crack, per Dryshield Basement Waterproofing (Toronto/GTA).
