The company that owns the apartment building wants the upgrade...we're just giving them a quote for doing it. The owner has been told 2 different things by 2 different companies and has asked me to show them the rule pertaining to this. We're in BC - our first large apartment building job.... Are the panels required to be upgraded with main breakers? If the panels need to be upgraded with main breakers, is that going to require the rest of the apartments to be brought up to code?

Thanks for the responses and the welcome.
