What We Do

Unlock the Full Potential
of Your Home

Your basement is one of the most valuable and underutilized spaces in your home. A professionally finished basement or a well-designed addition doesn't just add square footage — it adds livable, functional space that your family will use every day and that significantly increases your home's resale value.

At True North Construction Inc, we design and build basements and additions that feel like a natural extension of your home — not an afterthought. Premium finishes, proper permits, and our own skilled trades throughout.

Home theatres, wet bars, in-law suites, gyms, offices, and playrooms

How It Works

The Basement & Addition Process

From your first consultation to your final walkthrough — here's exactly how we deliver your basement or addition.

Free Consultation

We assess your basement or addition site, discuss your goals and budget, and give you an honest scope of what's achievable.

Design & Planning

We create your floor plan, finalize room configurations, select all materials and finishes, and scope the full project before work begins.

Permits & Engineering

We pull all building permits, obtain structural engineering where required, and handle every municipal approval — fully managed by our team.

Build & Finish

Framing, mechanical rough-ins, insulation, drywall, flooring, millwork, and all finishes — executed by our own trades on schedule.

Final Walkthrough

We walk through every room with you, resolve the deficiency list, and hand you back a space that's ready to use and built to last.

What Sets Us Apart

Why True North for Your Basement or Addition

Permits & Structure

Done Right,
Done to Code

Basement finishes and home additions are heavily regulated in Ontario — and cutting corners on permits or structural work creates serious problems down the road. We pull every permit, engage structural engineers where required, and build everything to current Ontario Building Code.

This protects your investment, your insurance, and your ability to sell your home with confidence. No shortcuts. No unpermitted work. Ever.

Home addition value by True North Construction

Add Real Value

Space That Pays
For Itself

A professionally finished basement or a well-built addition is one of the highest-ROI projects in residential construction. In Ontario's market, a quality basement finish or addition can return $1.50–$2.00 for every dollar invested when you sell.

Beyond resale value, you're gaining functional living space your family uses every day — whether that's a home theatre, a guest suite, a home office, or an in-law apartment that generates rental income.
