Why CNB in Mississauga

One crew. Fixed price.
Permits sorted.

Mississauga has its own Building Division at 300 City Centre Drive. This is NOT the City of Toronto — different application system, different plan examiners, different permit fees. Legal suites also require a Second Unit Licence from the City — CNB registers the unit for you. We manage the full Mississauga permit process: you don't deal with the city at all.

Mississauga permit — we handle it

Our BCin designer is licensed in the City of Mississauga. We submit at 300 City Centre Drive, respond to comments and manage all inspections.

Written scope before we start

Line-item scope signed before we start. We know Mississauga material conditions and subfloor specifics, so what we write is what you get.

WSIB + $2M liability

WSIB clearance on request. $2M liability. Same insurance as our Toronto projects.

Deep basements — our specialty

Most Mississauga homes have 8'–9' ceilings. We maximise that height with flush-beam framing and ceiling-height pot light placement.

FAQ · Mississauga

Questions about basement
renovation in Mississauga.

Do I need a permit from the City of Mississauga?

Yes. Mississauga is a separate city from Toronto with its own Building Division. CNB is licensed to pull permits in Mississauga. We manage the full process — you don't deal with the city at all.

How does the Mississauga permit work?

We submit a complete application on day one to avoid re-submission delays, respond to plan-examiner comments, and build the review into the schedule we give you upfront.

What goes into a basement renovation in Mississauga?

A standard finish covers framing, insulation, drywall, flooring and trim. A full legal suite adds a kitchen, bathroom, egress window and fire separation. Permit included. You approve a written scope before we start.

Can I build a secondary suite in Mississauga?

Yes — provincial law allows secondary suites across Ontario. Mississauga additionally requires a Second Unit Licence. CNB verifies your zoning setbacks, files the building permit, and registers the unit — delivered fully legal and rent-ready.

Do Mississauga basements need underpinning?

Rarely. Most 1980s–2010s Mississauga homes have 8'–9' ceilings — already above OBC minimums. We measure on site during the free consultation.
