Good evening Emmanuel,
Under the law, CAMA part C20 the minimum number of trustees for any Nonprofit is 2 while the they can be more than 10 if necessary..
For a person to be on a board of trustee he must be
1. An Adult,
2. He must not be a convict,
The plus of this is that only a sane person can be a Trustee.
Under the law, these are the only criteria that must be met before any one can become a board member of an NGO.
