ACMO is the Association of Condominium Managers of Ontario. Formed in 1977, it is Ontario’s only professional association dedicated to supporting, educating and promoting condominium managers, management firms and the supplier companies that serve them. It awards the Registered Condominium Manager (RCM) designation and ACMO 2000 Certification for management firms. Trades and service providers join as Associate Members.
What Is ACMO Membership?
ACMO was started in 1977 by property managers who wanted more consistency in a fast-growing industry. A year later, it opened membership to suppliers and vendors serving condominiums. It was incorporated as a not-for-profit corporation in 1981 and is based in Mississauga.
ACMO has several member groups. Condominium managers can earn the RCM designation, first awarded in 1984. Management firms can earn ACMO 2000 Certification, which audits how they run board relations, supplier relations and field operations. Associate Members are the companies that supply goods and services to condominium corporations, managers and management firms.

Why ACMO Membership Matters to Condo Boards & Managers
Condo buildings are shared homes. Work in one suite can affect neighbours, and work in common areas is paid for by every owner. That is why managers and boards are careful about which trades they bring in.

How We Support Condominiums & Multi-Unit Buildings
Multi-unit residential buildings are one of the property types we serve across Toronto and the GTA. Common condo requests include:
Lint build-up in long dryer vent runs reduces airflow and increases fire risk. See dryer vent cleaning.
Cleaning exhaust lines that carry moisture, grease and odours out of suites. See exhaust cleaning.
HRV core cleaning and balancing, plus duct cleaning for common-area and commercial-grade systems.
Before and after photos where applicable, which managers can share with the board and owners.
