Employers First

MCB is acutely aware of the potential dangers that exist in the construction environment.  

As a company very concerned with the health and safety of its employees and clients, MCB has acquired the services of “Employers First” to ensure we not only meet all legislative compliance in Employment Labour, Health and Safety Law but to make certain we take every step possible to minimize the risks typically associated with construction. 

We take all measures to reduce and/or eliminate the working conditions that may lead to serious injury, giving us the peace of mind so we can focus on our core objectives – our clients.

Tarion Warranty

What is Tarion?

Tarion is a non-profit, private corporation established in 1976 to protect the rights of new home buyers and regulate new home builders according to the terms of the Ontario New Home Warranties Plan Act (“the Act”). Not only does the Act require builders in Ontario to provide new home warranty coverage, but they must also be registered with Tarion and enroll every new home prior to the start of construction.

Tarion’s responsibilities cover the following areas:


Tarion offers a variety of information and resources to help homeowners and builders understand their rights and obligations under the Act.


Tarion works with homeowners and builders to help resolve disputes about statutory warranty coverage. They also manage a guarantee fund to ensure that the statutory warranty provided to new home buyers is honoured, or in the event of builder bankruptcy.


As the regulator of Ontario’s new home building industry, Tarion is responsible for licensing all new home and condominium builders in the province. During the licensing process, builders must demonstrate they have the technical experience, customer service capabilities and financial standing required to successfully build new homes in Ontario. Tarion also promotes a high standard of construction among Ontario builders.


Tarion employs a team of investigators to uncover builders and vendors in Ontario who fail to register and/or to enroll new homes with Tarion. The investigators partner with municipalities and building officials in Ontario to find and prosecute these offenders. Under the Act, fines of up to $100,000 can be imposed by Ontario Courts. In addition, convicted offenders may be imprisoned for up to one year, placed on probation and/or required to pay Tarion any monies owed.
