Residential facilities, apartments and/or planned communities for older adults, people with disabilities or other populations that are available at market rates and designed to enable those who are eligible to have a form of independent living in a secure environment while sharing common interests and having access to supportive services and a range of activities designed to promote social contact among residents. Occupancy by families with children may be discouraged. Housing varies widely from simple apartments to high rise condominiums to single family detached housing to housing in a congregate setting; and units may be available on a purchase or rental basis. Support usually consists of "convenience services" which may include an on-site activities program, transportation, housekeeping and meals in a communal dining room. Residents who require additional support need to make their own arrangements for personal care, home health care or other in-home services. Facilities in Alberta, British Columbia and Ontario must be licensed if they offer the option of fee-for-service supports to their residents.
