When it comes to protecting your home from Canada’s harsh weather, think heavy snow in Alberta, rainy seasons in British Columbia, or humid summers in Ontario, choosing the right exterior covering is crucial. Many homeowners wonder about cladding vs siding and whether they’re essentially the same thing. In this article, we’ll break down the differences, explore the best cladding solutions in Canada, and help you decide what’s best for your residential project. Whether you’re renovating in Toronto or building in Vancouver, understanding these terms can save you time, money, and headaches.
What is Cladding?
Cladding refers to any protective, non-structural layer applied to the exterior of a building. It’s designed to shield against elements like rain, wind, and extreme temperatures while often adding insulation and aesthetic appeal. In Canada, cladding is versatile and used on both residential homes and commercial structures. Materials can range from metal and stone to wood and composites, and systems often include features like ventilation gaps for better moisture control—essential in our variable climates.
Cladding isn’t just about looks; it’s engineered for performance. For instance, in regions with high precipitation, rainscreen cladding systems are popular to prevent water damage by allowing air circulation behind the material. According to the National Research Council of Canada, proper cladding installation can improve energy efficiency by up to 20% in cold climates.
What is Siding?
Siding is a specific type of exterior covering, typically used on residential homes. It consists of horizontal or vertical panels that overlap to create a weather-resistant barrier. Common in Canadian suburbs, siding is straightforward and focuses on basic protection and curb appeal. Materials like vinyl, wood, or fiber cement are staples, making them a go-to for budget-friendly updates.
Unlike more complex systems, siding is usually installed directly onto the wall sheathing, which suits many single-family homes across the provinces. However, in harsher environments like the Prairies, regular maintenance is key to longevity.
Is Cladding and Siding the Same?
No, cladding and siding are not the same, though the terms are sometimes used interchangeably, especially in casual conversations. Is siding cladding? Yes, siding is actually a subset of cladding. All siding qualifies as cladding, but not all cladding is siding. Cladding encompasses a broader range of applications and materials, often with advanced features for durability and energy efficiency. Siding, on the other hand, is more narrowly focused on residential use with simpler designs. This distinction matters in Canada, where building codes emphasize performance in cold winters and wet conditions.
For clarity, exterior cladding vs siding highlights that both are used outdoors, but cladding offers more options for commercial or modern residential builds. Regarding interior cladding vs siding, siding is almost exclusively exterior, while cladding can refer to interior wall panels (e.g., wood cladding for accent walls in living rooms). If you’re considering interior applications, cladding provides more decorative flexibility without the weatherproofing focus.
Key Differences Between Cladding and Siding
To make it clearer, here’s a comparison of the main differences:
| Aspect | Cladding | Siding |
|---|---|---|
| Scope | Broader term for any exterior covering; used in residential and commercial buildings. | Specific to residential homes; a type of cladding. |
| Materials | Diverse: metal (e.g., aluminum), stone, brick, glass, composites, wood. | Typically vinyl, wood, fiber cement, or engineered wood. |
| Installation | Often multi-layered with ventilation or drainage systems for moisture management. | Directly attached to walls; simpler and faster to install. |
| Durability | Generally more robust, with better resistance to extreme weather; thicker panels. | Good for everyday use but may require more maintenance in harsh climates. |
| Cost | Higher upfront due to materials and complexity; long-term savings on energy. | More affordable and easier for DIY or quick renos. |
| Aesthetics | Modern, customizable for high-end looks. | Traditional, versatile colors and styles for suburban appeal. |
These differences highlight why cladding might be preferred for custom builds in urban areas like Montreal, while siding dominates in suburban neighborhoods across the Prairies.
Cladding vs Siding Cost and Price Comparison
One of the most common questions is cladding vs siding cost or cladding vs siding price. Costs vary by material, region, and installation, but here’s a general breakdown based on 2025 Canadian averages (sourced from local manufacturer and contractor estimates):
- Vinyl siding: $5-10 per square foot installed, making it the most budget-friendly option for quick updates.
- Wood siding/cladding: $8-15 per square foot, with cedar being pricier due to its natural rot resistance.
- Fiber cement siding: $10-18 per square foot, offering a good balance of cost and durability.
- Metal cladding (e.g., aluminum): $12-25 per square foot, ideal for long-term investment in windy areas.
- Composite cladding: $15-30 per square foot, with eco-friendly options providing energy savings over time.
Overall, siding tends to be 20-30% cheaper upfront than advanced cladding systems, but cladding can reduce heating bills by 15-25% in provinces like Ontario. Always get quotes for cladding from local pros.
Popular Exterior Cladding and Siding Materials in Canada
Canada’s diverse climates influence material choices. Here are some top options, with pros and cons:
- Vinyl Siding: Affordable and low-maintenance; resists fading in sunny provinces like Saskatchewan. Pros: Easy install, wide colors. Cons: Can crack in extreme cold.
- Wood Cladding/Siding: Cedar or redwood for a natural vibe; treated for rot resistance in wet areas like the Maritimes. Pros: Aesthetic appeal. Cons: Requires staining every 3-5 years.
- Fiber Cement: Durable against freeze-thaw cycles in Ontario and Quebec; mimics wood without the upkeep. Pros: Fire-resistant. Cons: Heavier, higher installation cost.
- Metal Cladding (e.g., Aluminum): Excellent for modern designs in all around Canada; withstands high winds and corrosion from salt in coastal regions. Pros: Long-lasting (50+ years). Cons: high up-front cost.
- Composite Materials (ACM/WPC): Eco-friendly and energy-efficient; growing in popularity for Toronto’s green building trends. Pros: Sustainable. Cons: Higher initial price.
Stone and brick are also favored for their timeless appeal in historic areas like Quebec City.

Canadian Building Codes for Cladding and Siding
The National Building Code of Canada (NBC) sets the standards, adopted with variations by provinces. For example:
- Wood siding must be at least 14.3 mm thick and no wider than 286 mm for certain styles (per NBC Section 9.27).
- Vinyl products need to meet CAN/CGSB-41.24 standards for rigidity and attachment. [Source]
- Rainscreens are often required in high-rainfall zones like BC to ensure proper drainage (BC Building Code Amendment).
Always check local codes—e.g., Ontario Building Code or BC Building Code—for specifics, as they address energy efficiency and fire resistance. For the latest, visit the National Research Council Canada’s official site.
Tips from Canadian Cladding Experts
As noted by Sam Ghara, Wiedehopf’s sales team lead, “In our variable weather, prioritize moisture management—cladding with rainscreens can prevent costly mold issues.” A study by the Canada Mortgage and Housing Corporation on building envelope failures supports this, highlighting that proper design can prevent high repair costs, with problem buildings averaging $7,152 per unit in repairs.

Which Should You Choose: Cladding or Siding?
It depends on your needs. For a quick, cost-effective refresh on a bungalow in Calgary, siding might be ideal. If you’re aiming for a high-performance, modern facade in Ottawa with better insulation, opt for cladding. Consider your budget, climate, and home style—consult a local cladding expert to ensure compliance with Canadian standards.
In summary, while cladding and siding overlap, their differences in scope, materials, and functionality make them suited to different projects. By choosing wisely, you can enhance your home’s value and withstand whatever Mother Nature throws at it in the Great White North. If you’re planning a project, start by assessing your local weather patterns and building requirements.
