Warehouses, Factories, Offices & More | From $250/Month
Headquartered in Markham since 2007. Serving Highway 7 tech offices, Birchmount Road warehouses, Unionville professional districts, and every corridor in between.
Zusashi Maintenance is headquartered at 7030 Woodbine Ave, Suite 500, Markham — not a franchise dispatched from Toronto, not a call centre booking jobs across the GTA. We are a Markham business serving Markham businesses. That matters when a client walks in unexpectedly, when there's a 6 AM shift change at a Birchmount warehouse, or when a Highway 7 tech office needs a same-day clean before a board meeting.
Markham is one of Canada's most commercially diverse cities. The Highway 7 corridor between Warden and Woodbine is home to Canadian headquarters for IBM, AMD, Huawei, and dozens of mid-size tech firms — office environments that require professional, security-aware cleaning crews with reliable after-hours access. The Birchmount/Hwy 404 industrial zone hosts warehousing, manufacturing, and distribution operations running around the clock. Unionville's Main Street has heritage retail and professional practices that need careful, detail-oriented cleaning. And Cornell and Cathedraltown are growing residential-commercial mixed districts with their own business park clusters.
We've operated across every one of these corridors since 2007 — before many of the Highway 7 towers broke ground. $5M insured, WSIB compliant, no long-term contracts, same-week start.
Highway 7 (Warden to Woodbine): Canadian HQ corridor for IBM, AMD, Huawei, and 40+ mid-size tech firms — after-hours-only access, security fob check-in, cleaning logs required. Birchmount Rd / Hwy 404 industrial zone: Markham's largest warehouse and manufacturing cluster; shift-window cleaning 10 PM–4 AM standard. Milliken industrial park (Steeles Ave E): light industrial and food-processing facilities straddling the Scarborough–Markham border. Unionville / Main Street: heritage retail, professional offices, medical and dental — detail-oriented cleaning for older, character buildings. Cornell / Cathedraltown: growing mixed-use commercial with medical plazas, professional services, and Markham Stouffville Hospital nearby on 9th Line.
We also hold contracts in sub-areas — see Downtown Markham commercial cleaning, Highway 7 Business District, janitorial services Markham, and our Richmond Hill and Scarborough pages for the wider east-end GTA.

Local cleaning services across every area of Markham, Ontario
Markham has four distinct commercial sectors, each with its own cleaning standards, access requirements, and compliance needs. Here's how we serve each one.
The Highway 7 stretch between Warden and Woodbine is one of Canada's most concentrated tech corridors outside downtown Toronto. IBM, AMD, and Huawei maintain Canadian headquarters here, alongside dozens of mid-size software, engineering, and professional services firms. Cleaning for these clients happens entirely after hours — crews sign in with building security, use approved carts in shared corridors, and submit digital or paper cleaning logs after every visit. Property managers for multi-tenant towers along this strip require active communication, documented service records, and winter salt-tracking from November to March to protect lobby and elevator floors. We hold multi-year contracts with both individual tenants and building management companies throughout this corridor.
Corporate office contracts from $850/month · Cleaning logs provided · Security fob check-in standard
Markham's industrial zones — Birchmount Road corridor, Milliken industrial park along Steeles Avenue East, and the Buttonville/Highway 404 precinct — house hundreds of warehouses, manufacturing plants, and distribution centres. Cleaning windows in these facilities are tight: typically 10 PM to 3 AM between production shifts. We deploy ride-on floor scrubbers for large concrete floor areas (ranging from 10,000 to over 100,000 sq ft), industrial degreasers for machinery surrounds and loading dock aprons, and full-service staff facility cleaning — lunchrooms, locker rooms, washrooms, and administrative offices — under a single contract. Multi-shift scheduling is available where operations run 24/7. Shift supervisors receive a WhatsApp or SMS confirmation when our crew departs each night.
Industrial contracts from $1,800/month · WSIB compliant · Multi-shift scheduling available
Markham Stouffville Hospital on 9th Line (expanded in 2018) anchors a growing healthcare corridor in northeastern Markham and Stouffville, with a dense ring of specialist clinics, family practice offices, physiotherapy centres, and diagnostic imaging facilities throughout Cornell, Cathedraltown, and the Hwy 7/McCowan area. All healthcare cleaning follows IPAC protocols — written procedures specifying contact time, dilution ratios, and sequence of cleaning with DIN-registered disinfectants. We supply written service logs after every visit for accreditation compliance. Medical waste handling procedures are observed in any space with sharps containers or biohazard waste streams. Unionville's Main Street also has a cluster of established dental and medical practices in older commercial buildings — we bring the same protocols and adapt to older building layouts and plumbing.
Healthcare contracts from $550/month · IPAC-compliant · Written logs every visit
Unionville's historic Main Street and Markham Village's heritage commercial core are home to boutique retail, law firms, financial advisory practices, and owner-operated professional offices that require careful, detail-oriented cleaning — hardwood floors, older tile, and character storefronts that can't tolerate heavy machinery or abrasive products. The McCowan/Ellesmere corridor near Markville features professional plazas and suburban medical offices with high daily foot traffic. We use appropriate products for each surface type and provide flexible scheduling — early morning before doors open or late evening — to minimize disruption to client-facing businesses. Day porter service is available for higher-traffic retail and service locations requiring daytime restroom monitoring and common-area upkeep.
Retail & professional contracts from $250/month · Day porter available · Heritage-appropriate products
Markham's four distinct commercial sectors — Highway 7 tech corridor, Birchmount industrial belt, Unionville heritage retail, and Cornell/Cathedraltown medical district — each operate on different cleaning schedules and carry different compliance expectations. Here's how Markham businesses typically structure their programs.
IBM, AMD, Huawei, and the 40+ tech firms along the Highway 7 Warden-to-Woodbine corridor typically require nightly or 3-times-a-week cleaning after staff have left. Building management enforces fob and security sign-in for all after-hours contractors. Cleaning logs are standard for larger tenants. Open-plan offices with hot-desking require daily disinfection of keyboard surfaces and phone handsets.
Recommended: Nightly or 3x/week
Warehouses and manufacturing facilities on Birchmount Road and the Milliken industrial park along Steeles Avenue East typically run overnight cleaning between shifts. Most require 5–7 day coverage. Floor scrubbing of large concrete areas (10,000–80,000+ sq ft), racking zone dust-down, loading dock maintenance, and employee lunchroom/washroom service are standard scope. WSIB and liability documentation required by most industrial facility managers.
Recommended: Nightly, 5–7 days
Markham Stouffville Hospital (9th Line) anchors a growing ring of specialist clinics, family health teams, dental practices, physiotherapy centres, and imaging facilities in the Cornell and Cathedraltown areas. All healthcare cleaning requires daily service, DIN-registered disinfectants, and written IPAC service logs. The healthcare district on 9th Line has expanded significantly since 2018 with multiple new medical plaza developments still completing their tenant fit-outs.
Recommended: Daily (IPAC mandatory)
Unionville's heritage retail strip on Main Street requires careful cleaning protocols — older hardwood floors, heritage plank, and stone facades are common and require specific (non-bleach, non-abrasive) products that won't damage finished wood or grout. Most Unionville merchants clean 3–5 times per week, with daily cleaning during peak seasonal periods (spring Unionville Festival, summer weekend markets, October Doors Open).
Recommended: 3–5 days/week
Markham has a significant concentration of private schools and licensed childcare centres — particularly in the Unionville, Cornell, and Cachet areas. Private schools typically need nightly cleaning after dismissal (4–10 PM window) plus weekly deep cleans of gyms, labs, and common areas. CCEYA-regulated childcare centres require daily cleaning with low-VOC, child-safe disinfectants on all contact surfaces, play areas, and washrooms. We hold active contracts with multiple Markham childcare centres and understand the regulatory expectation.
Recommended: Daily (childcare); nightly (schools)
Professional services offices (law, accounting, immigration) scattered through Downtown Markham, Warden South, and McCowan Road plazas typically choose 2–3 times per week service. Retail plazas along Highway 7 and Sheppard Avenue East use daily or 5-day cleaning. Property management companies overseeing multi-tenant commercial buildings often standardize cleaning frequency and products across all tenants — we work regularly with York Region property managers who manage several Markham plazas simultaneously.
Recommended: 2–5 days/week
Several recurring Markham events create concentrated cleaning demand that smart facility managers plan for in advance. Unionville Festival (May) brings thousands of visitors to Main Street over a weekend — post-event deep cleans for heritage retail are typically pre-booked. Tax season (February–April) increases cleaning frequency at Highway 7 accountancy offices as client volume peaks. The Markham Fair (October, Markham Fairgrounds) generates demand for fairground facility cleaning before and after the event. Tech sector end-of-quarter periods (March, June, September, December) often bring all-hands meetings to Highway 7 corporate campuses, requiring enhanced common-area cleaning during peak occupancy periods. We build these calendar markers into recurring contracts for clients who have predictable seasonal intensity changes.

Commercial cleaning throughout Markham and the Greater Toronto Area
Markham has the highest concentration of Chinese Canadians outside Vancouver, a large Korean community in Thornhill Village, and one of Canada's densest tech office clusters. Each of these communities generates distinct cleaning needs that go beyond a standard office contract.
Markham's Chinese Buddhist temples — including facilities in the Unionville and Markham Town Centre areas — require cleaning that respects the sanctity of the main hall, incense ash management, and high foot-traffic handling during major festivals like Qingming, Vesak, and Ullambana. Cultural centers serving Markham's Cantonese- and Mandarin-speaking communities host language classes, seniors' programs, and community events with daily or weekly cleaning needs. No pork-derived cleaning products are used in any facility. Staff are briefed on temple protocols including head-covering requirements and quiet-hour scheduling around morning prayers.
Incense ash management · Festival deep-clean service · Temple protocol training for staff
Korean Presbyterian and non-denominational megachurches in the Markham–Thornhill border area operate large campuses with multiple Sunday services, mid-week prayer meetings, and youth programs that generate layered cleaning schedules. South Asian mandirs in the Cornell and Angus Glen areas draw large festival congregations — Navratri, Diwali, and Holi events — requiring overnight post-festival cleaning. We handle multi-building campus scheduling, childcare and nursery room sanitization, kitchen and fellowship hall servicing, and washroom maintenance on recurring weekly contracts.
Multi-service Sunday cleaning · Post-festival overnight service · Korean and South Asian community experience
Markham's Highway 7 and Warden Avenue tech corridor — home to IBM Canada, AMD, Bank of Montreal's tech hub, Hyundai's design centre, and dozens of software and engineering firms — generates demand for corporate cafeteria cleaning, atrium and common-area maintenance, and multi-floor office janitorial service. Tech campuses typically have open-plan floors that require quiet-mode evening cleaning, server room access protocols, and cleaning sign-off documentation for security compliance. Corporate cafeterias require food-safe kitchen cleaning to Public Health Ontario restaurant standards, even when the cafeteria isn't open to the public.
