Most non-profit housing co-ops are (or were) funded by government programs. The programs have different rules, and three of those programs set income ceilings for members on move-in.
Section 61 co-ops, Homes BC co-ops and a few Index-Linked Mortgage (ILM) co-ops have income ceilings, as do most co-ops built since 2010 in the City of Vancouver. The dollar amount of the income ceiling varies.
Please note that co-ops that are built on leased land may also see income ceilings now or in the future as part of their lease agreements.
