Building a 1800 square foot house in Canada will cost you between $270,000 to $900,000+ in 2025 for custom builds, or $240,000 to $500,000 for production homes, also depending on your location, materials, and finishes. If you're looking at major Canadian cities like Toronto or Vancouver, expect to pay $515-$1,130 per square foot for custom construction, or $200-$315 per square foot for production builds with limited design flexibility, while smaller markets like Halifax might run $275-$500 per square foot. This estimated cost doesn't include land purchase, which can add another $50,000 to $500,000+, depending on where you want to build your dream home.
The construction landscape has stabilized after the pandemic chaos, affecting the overall cost to build a house in Canada, but labour costs and material costs are still keeping prices elevated. Most folks I talk to are shocked when they realize their realistic budget needs to account for way more than just the basic construction you've got permits, inspections, utility connections, and about a dozen other "surprise" costs that can easily add $50,000 to your final cost. Whether you're working with several contractors or a single general contractor, understanding these costs upfront through residential estimating services Canada is crucial for your new house project.

⚠️ 2025 Market Alert: Tariff Impact
U.S. tariffs on Canadian lumber have increased to approximately 35% (combining countervailing and anti-dumping duties), plus an additional 10% tariff imposed in late 2025. This has caused:
- Mill closures across Canada, particularly in Western provinces
- Lumber supply tightening and price volatility
- Estimated $10,000-$15,000 added to typical home construction costs
- Extended lead times for material delivery

What's Really Driving Construction Costs in 2025?
Let me be straight with you, construction costs aren't what they used to be. After dealing with hundreds of estimates this year, I've seen how the market has shifted since the pandemic madness settled down. Much does it cost to build a house now? Well, several factors are driving these price ranges higher than most homeowners expect.
Labor Shortage Reality Check
The biggest cost driver? Finding skilled trades. Construction laborers now earn $22-34 per hour nationally, with Ontario workers averaging $30 per hour. Specialized trades like electricians and plumbers command $35-50 per hour, and union rates in major urban centers can reach $50-60 per hour. Contractor availability varies by location, and when your general contractor tells you they can't find a framer for three weeks, that delay costs you money in carrying costs and extended timelines. Working with several contractors individually often costs more than hiring one experienced custom home builder who manages the entire building process.
Material Costs Have Plateaued (Finally)
Good news here. Lumber prices have come back down to earth after that insane spike in 2021-2022, meaning you can build a house with fewer materials cost concerns. But don't get too excited other building materials like concrete walls, steel, and insulation are still running 15-20% higher than pre-pandemic levels. The supply chain hiccups are mostly sorted, but manufacturers haven't rolled back their price increases. Market fluctuations still affect everything from hardwood flooring to luxury fixtures.
Regional Variations Are Extreme
Here's where it gets interesting. Building the exact same 1800 sq ft house can cost you $480,000 in Vancouver but only $270,000 in Halifax. It's not just about local wages land development costs, municipal fees, and even weather conditions play huge roles in your overall costs. Rural areas typically offer lower costs per square foot, but you might face higher expenses for utility connections, septic system installation, and material delivery to your construction site.
Breaking Down Your 1800 sq ft House Budget
Foundation and Structure (25-30% of total cost)
For your 1800 sq ft footprint, you're looking at:
- Foundation with unfinished basement: $22-26 per square foot ($40,000-$47,000)
- Concrete walls and foundation: $15,000-$25,000 for standard residential
- Framing and structure: $15-25 per square foot ($27,000-$45,000)
- Roofing: $8,000-$15,000 depending on materials
The foundation is where you don't want to cut corners. I've seen too many projects where folks tried to save a few grand on the foundation only to deal with moisture issues later that cost ten times more to fix. Site preparation for your construction site can add another $5,000-$15,000 depending on terrain and access.
Major Systems (20-25% of total cost)
- HVAC installation: $13,000-$17,000 for a complete system
- Basic electrical rough-in and finish: $13,000+ (code requirements keep getting stricter)
- Plumbing: $4.50 per square foot ($8,100 for 1800 sq ft square footage)
- Utility connections: $5,000-$12,000 for water, sewer, gas, and electrical hookups
Pro tip: Get your electrical planned early. With all the smart home tech and electric vehicle charging requirements, basic electrical rough-ins just don't cut it anymore for a modern single family house.
Finishing Work (30-40% of total cost)
This is where your finishing costs can explode or stay reasonable:
- Drywall and painting: $8,000-$12,000
- Hardwood flooring vs basic options: $10,000-$25,000 (huge range based on materials)
- Kitchen and bathroom fixtures: $15,000-$60,000+
- Custom cabinetry vs stock options: $8,000-$35,000
- Interior trim and doors: $8,000-$15,000
- Basic fixtures vs luxury fixtures: Can double your bathroom costs
The difference between basic fixtures and premium materials in your kitchen and bathroom can easily add $30,000 to your total budget. Many homeowners choose a mix luxury fixtures in the master bath and basic fixtures in secondary bathrooms to balance their total cost.
