For most small Toronto firms, an after-hours or weekend office move costs about 20 to 40 percent more on the mover's fee but saves far more in avoided downtime. The math is simple: total cost equals the mover's fee plus your hourly operating cost multiplied by the hours your team cannot work. A weekday move that idles a 10-person office for a day often costs more in lost payroll than the weekend surcharge. Many downtown towers also ban business-hours moves outright, so the choice is frequently made for you. When you compare quotes from office movers Toronto firms rely on, run the downtime number first, then the invoice.
