Here is a link to the real estate act

You need a license to trade in real estate. Trade as it relates to property management is defined as follows:
"(s.1) `property management` includes any of the following:
(i) leasing or offering to lease real estate or negotiating
or approving, or offering to negotiate or approve, a
lease or rental of real estate;
(ii) holding money received in connection with an
activity referred to in subclause (i);
(iii) advertising, negotiating or carrying out any other
activity, directly or indirectly, for the purpose of
furthering an activity referred to in subclause (i) or
(ii);
If you want to do showings and leasing for more than one person and make
money doing so you have to be licensed with a brokerage that trades in
property management. So more than just a regular old realtor. To receive rents and hold security deposits you need two trust accounts. Most real estate brokerages only do buy/sell and don't allow their agents to do property management.
