What constitutes a BCIN designer?

A BCIN designer needs to pass written examinations provided by the Ministry of Municipal Affairs and Housing. Once the design firm and designer have past their examinations, they must stay in good standing and keep their E&O insurance current to be a qualified BCIN designer.

However, holding a BCIN license should not be the only way to select a design firm. 

Designers should have past projects along with testimonials on their projects. You'll be looking for design creativity as well as have good technical knowledge of drafting. A designer that can foresee challenges and obstacles in your design process makes for an optimal designer. It's one thing to pass an exam, but quality design work is a skill that comes with time and experience.
