Retail TI From Grey-Shell To Grand-Opening.

Retail buildouts in the GTA in 2026 span the widest cost range of any commercial vertical — a kiosk refit in Yorkdale runs $80/sf, a flagship boutique on Yorkville hits $280/sf, and a franchise apparel store in a Premium Outlets center lands in the middle at $130-$160/sf. The variable isn't ambition; it's landlord requirements (some malls require Class A construction with specific trades), brand standards from the franchisor, and demising-wall fire ratings. AOV: $180K (1,500 sf boutique) to $1.2M (5,000 sf flagship).

What makes retail different from office or medical is that you're often working inside an active shopping centre with strict construction-hour rules (typically 11pm-7am inside enclosed malls), barricade and dust-protection specs reviewed by mall ops, freight-elevator booking windows, and demolition debris removal logistics that turn what looks like a 6-week project on paper into 10-12 weeks on the ground.

2026 GTA Pricing Tiers

Floor — $80-$120/sf ($150K-$350K project) Simple refit of existing retail, light demo, paint, new fixtures, basic LED lighting upgrade to 1500 lm/m², minor electrical (no service upgrade), new floor (LVP like Shaw 5mm or Mannington Spacia), basic POS counter in laminate. Best-suited to value retail, mobile carriers, small QSR.

Standard — $130-$190/sf ($380K-$900K project) Full buildout from grey shell in a mall or street-front: demising wall to landlord 1-hr fire rating, suspended drywall ceiling with custom soffit lighting, polished concrete or porcelain tile floor (Daltile or Olympia), custom millwork casework, 3-phase electrical service upgrade (typical 200A 120/208V to 400A), rooftop HVAC tie-in or supplemental Mitsubishi VRF, AODA service counter section (1830mm length max 865mm height), one accessible fitting room (1500mm clear turning radius).

Premium — $220-$280/sf ($1M-$2.5M project) Flagship boutique or luxury concept — Yorkville, Bloor, Yorkdale Premium, CF Sherway. Custom millwork in walnut/oak veneer (Henrybuilt or Mattamy Millwork tier), specialty lighting like Erco or iGuzzini track + accent, terrazzo or large-format porcelain (1200x2400mm slabs), integrated AV with digital signage, custom HVAC zoning with humidity control for textiles, full glass storefront with motorized swing door (Stanley Magic or Horton), back-of-house workspace + secure stock room with electronic access control.

Code & Regulatory Compliance

• OBC Part 3 (most malls and Class A street-front) or Part 9 (small standalone) — fire separations between tenants typically 1-hr; if your unit is adjacent to a stock room with hazardous storage or above/below residential, 2-hr.
• Demising wall construction — 1-hr fire-rated wall is typically 1x 5/8" Type X each side of 92mm steel stud at 406mm o.c., extending slab-to-slab (NOT to ceiling — slab-to-slab is the test, and a frequent fail point). 2-hr is 2x 5/8" each side.
• AODA Design of Public Spaces + s. 80.27 (built environment) — service counter accessibility section, fitting room accessibility, washroom if provided to public, signage with tactile and Braille at permanent rooms.
• Ontario Fire Code — emergency lighting, exit signage, fire extinguisher rated 2A-10BC every 25m of travel, sprinkler density adjustments if you add high-pile racking (>3.7m).
• Ontario Electrical Safety Code (OESC) 27th ed. — for retail with display kitchens, espresso bars, juice bars, etc., dedicated GFCI/AFCI per current OESC. Service sizing must account for HVAC + lighting + receptacle + signage exterior.
• TSSA (if any gas) — retail with gas-fired equipment (rare except for in-store cafe) triggers TSSA permit.
• Toronto Sign Bylaw 297-2018 — exterior sign permit separate from building permit; restrictions on illumination intensity, projection, heritage district overlays. Yorkville, Distillery, Queen W. Conservation Zone all have additional layers.

5-Micromarket Considerations

Downtown core (Bloor / Yorkville / Eaton Centre / Yonge) — Premium AAA. CF Toronto Eaton Centre, Yorkville Village have strict TI design review by landlord (typically Cadillac Fairview or Bayview Place Mgmt). Construction hours 11pm-7am only; barricade specs custom per landlord; landlord-approved trades only for fire stopping, sprinklers, life safety. Add 15-25% over Mississauga pricing for these constraints alone.

North York / Scarborough / Etobicoke — Yorkdale, Fairview, Scarborough Town, Sherway. Mid-tier mall standards; slightly more flexibility on hours; better freight access. Yonge-Eglinton and Yonge-Sheppard street-front are gentrifying with higher-than-suburb expectations.

Mississauga / Brampton (Square One / Bramalea / Erin Mills) — Largest GTA mall (Square One) — full ORC mall TI standards similar to Yorkdale. Suburban plazas easier, more straightforward.

East York / Leslieville / Queen W. / Ossington — Heritage-district overlay common. Storefront preservation, signage restrictions, and Toronto Heritage Preservation Services review on facade. Interior largely unconstrained but exterior modifications can add 6-8 weeks to permit.

905 north (Vaughan Mills / Promenade / Hillcrest) — Vaughan Mills is a Premium Outlets-style center with tenant manuals as long as the OBC. Strict adherence to mall fixturing standards. Brand standards from US-based franchisors (Lululemon, Aritzia, Sephora) often override Canadian code in spec sheets — contractor must reconcile both.

Project Timeline

• Week 0-3: Brand standard / design package finalization
• Week 3-6: Permit application + landlord design review (parallel)
• Week 6-7: Permit issuance + freight elevator booking
• Week 7-9: Demo + barricade
• Week 9-13: MEP rough-ins, framing, ceiling grid
• Week 13-15: Drywall, prime, paint, floor
• Week 15-17: Casework, millwork, lighting, signage
• Week 17-18: Fixturing (often retailer's own team), inspections, opening

Typical 2,500 sf street-front: 14-18 weeks. Mall TI with overnight-only constraint: 16-22 weeks.

TI Allowance & Landlord Coordination

Retail TI varies hugely by landlord segment in 2026:

• AAA mall (Yorkdale, Eaton Centre, Sherway, Square One): $40-$120/sf, 7-10 yr lease, percentage rent kicker
• B-mall (Scarborough Town, Bramalea): $25-$60/sf, 5-7 yr lease
• Street-front Yorkville / Bloor / Queen W.: $20-$80/sf, 5-10 yr lease
• Power centre or strip plaza: $15-$40/sf, 5 yr lease + options
• Outlet center (Vaughan Mills, Toronto Premium): $30-$70/sf with brand spec review

Must-resolve items: HVAC tonnage allowance for retail occupant load (typically 350 W/m² minimum), electrical service capacity (200A minimum, 400A for any food or coffee program), demising wall fire rating responsibility (typically tenant), grease venting if any cooking (almost never permitted in standard retail leases), signage rights on facade + directory.

Specialty Trade Coordination

Retail buildouts typically run 8-12 specialty trades on top of standard GC: storefront and entrance system (Stanley Magic-Force or Horton Series 7000 automatic sliding/swing for AODA compliance); structural mall-front bulkhead (often heavier-gauge framing with motorized rolling shutter on mall side); landlord-approved fire-stopping (3M, Hilti, STI); landlord-approved sprinkler trade (often a short list of 2-3 firms per major mall); demountable fitting room hardware (Larson or custom); custom millwork shop (front-of-house casework, POS counter, back-of-house stock fixtures); signage (interior + exterior, both lit and non-lit, with brand-standard graphic package); structured cabling and POS networking; LED accent and track lighting (Erco, iGuzzini, Litelab, Soraa for color rendering on apparel); flooring specialist (large-format porcelain installer with rated thinset for substrate). Most retailers handle FF&E (fixtures, fittings, equipment) separately from base TI contract — typical FF&E adds 30-60% on top of construction cost.

Bottom Line

Retail TI is won at the LOI stage, not the construction stage. The decisions that determine whether your buildout lands at $130/sf or $220/sf are: which landlord, what hours can you work, who pays for the demising wall, what HVAC tonnage is allocated, and what's the franchisor's brand-standard floor plate. Get those locked at letter-of-intent and the construction phase is mostly trades execution. Sign first, negotiate later, and a $400K budget becomes $650K fast.
