Medical Office Buildout in Caledon

Generally no — CSA Z32 applies to procedure rooms doing moderate sedation or where life-support equipment is in use. A family practice doing routine exams, vaccinations, and minor in-office procedures (suture removal, skin tag) does not. A clinic doing IV-sedation cosmetic procedures, dermatology with electrocautery, or fluoroscopy generally does. Have your electrical engineer scope this with the medical director early.

A 120 sf exam room with 2.7m ceiling is ~325 cf. Six air changes per hour is 1,950 cfh or 33 cfm of supply. That's roughly one 6" round diffuser per exam room. Procedure rooms at 12 ACH double that. The real cost driver is the dedicated exhaust path for soiled utility and washrooms — those can't tie into general return.

A standard 9' x 12' general radiography room shielded to 1.5mm Pb walls/ceiling/door runs $35-$60K in 2026 GTA pricing, including the medical physicist shielding calculation, Pb-lined drywall, lead door, lead-glass control window, and post-install survey. Fluoroscopy or mammography rooms run higher (2.0mm walls).

Depends on zoning, base-building exhaust capacity, and biomedical waste pickup logistics. Most CMHC-financed office towers and Class A buildings will allow medical use, but the lease will likely cap procedures generating biohazard sharps unless you contract a licensed biomedical waste hauler (Stericycle is the dominant GTA player). Zoning verification is the first call.

Caledon Building review of a medical TI without imaging: 8-12 weeks. Add 6-10 weeks if you're doing X-ray and need Ministry of Health imaging unit installation approval. 905 municipalities run slightly faster (6-10 weeks for medical TI without imaging).
