2026 Renovation Cost Guide for Canadian Homeowners (Kitchen, Bath, Waterproofing, Interlock)

After 50+ years and 30,000+ completed renovation projects across the GTA, here is LF Builders’ practical reference guide for Canadian homeowners planning projects in 2026.


Kitchen Renovations

Entry-level refresh (new cabinet doors, counters, paint — no layout changes): $8,000 – $20,000

Mid-range full renovation (new cabinets, quartz countertop, backsplash, lighting update): $25,000 – $55,000

High-end custom (custom cabinetry, layout change, premium appliances): $60,000 – $150,000+

Key 2026 note: Premium wood-tone cabinetry (white oak, walnut) runs 20–35% more per linear foot than painted shaker doors. Framing lumber and structural costs are up roughly 5% year over year.


Bathroom Renovations

Basic refresh, same layout (new fixtures, accessories, paint): $6,000 – $15,000

Full gut, same layout (new tile, vanity, tub or shower, fixtures): $15,000 – $35,000

Layout changes (moving drains, walls, full reconfiguration): $30,000 – $60,000+

Worth adding during any bathroom reno: heated floor coils. Modest cost at installation ($1,500–$4,000 depending on room size), and nearly impossible to add affordably after the floor tiles are laid.


Basement Waterproofing

Interior drainage system and sump pump: $5,000 – $15,000

Exterior excavation (partial, one wall): $15,000 – $30,000

Full exterior perimeter system: $35,000 – $65,000+


Interlock Driveways and Patios

Walkway interlock: $15 – $25 per sq ft installed

Driveway interlock: $20 – $35 per sq ft installed

Natural flagstone: $40 – $80 per sq ft installed


Secondary Suites

Basic legal conversion (egress windows, fire separation, dedicated electrical): $40,000 – $65,000

Mid-range with separate entrance and full fit-out: $65,000 – $110,000

Full build requiring underpinning: $110,000 – $200,000+

Toronto building permits for suite additions typically add $1,500 – $4,000.


Roofing

Material Cost Range (1,500 sq ft home)
Architectural shingles $8,000 – $18,000
Metal roofing $15,000 – $35,000
Flat roof (torch-on/TPO) $8,000 – $20,000

Contingency Rule

Budget 15–20% above your quoted price as contingency. In pre-1970 Toronto homes, use 25%. Hidden conditions — asbestos, knob-and-tube wiring, cast iron drains, subfloor rot — appear in the majority of older GTA renovations. After 30,000+ projects across Southern Ontario, this number is consistent.
