The Requirements .........
The National, Provincial and Municipal fire codes require
that certain types of occupancies have in place a Fire Safety Plan. This
plan must be approved by the local 
municipal Fire Chief and implemented
with the building owner and on-site personnel.
Fire Safety Plans must conform to guidelines and requirements of the National and Provincial Fire Code. Section 2.8.1 of the Ontario Fire Code outlines the specifics.
Failure to comply can result in fines of not more than $50,000 for an individual or $100,000 for a Corporation or to imprisonment for a term of not more than one year or both. Directors and officers who know the company has committed a violation of the fire code is guilty of an offence and on conviction is liable to a fine of not more than $25,000. Failure to comply with an inspection order can result in a fine of $10,000 per day.
The building owner or tenant has a legal duty to ensure that the
building and/or leased space complies with the 
regulations
at all times even if the building has not been inspected by the fire department.
If you have a fire alarm system consider having a fire safety plan.
The Building codes classify buildings by their 'Major Occupancy'. These classifications include assembly, residential, business, mercantile, and industrial occupancies.
