• The cost of building or replacing a deck or porch in Canada can range from $2,250 to $20,000, with the median cost coming in at $8,750. 
• The cost of building or replacing a deck or porch in Canada can depend on a number of factors, including the size of the structure, whether it is a single- or multi-level, what type of materials are used, and any additional features you might decide to add.
• Labour is typically the most expensive part of the project, with costs ranging from $13-$20 per square foot of natural wood such as pine, cedar or redwood. Vinyl and composite materials are more difficult to work with, so you should expect to pay more in the neighbourhood of $18-$32 per square foot for installation.
• The cost of materials is the next thing to consider. Wood is the most affordable material, with prices ranging from $8-$50 per square foot for pressure-treated pine. Cedar ($20-$75 sq. ft.) and redwood ($30-$75 sq. ft.) are also popular choices with homeowners. A vinyl or composite deck requires very little maintenance and will last for 30 years or more, but installation can cost $25-$70 or more per square foot.
• If you are replacing an existing deck or porch in Canada rather than adding new construction, you should also factor in the cost of demolition and removal of the structure to be replaced. Depending on the size, complexity and type of materials used in construction, the cost of demolition, removal and leveling can range from $300 to $2,000.
• Depending on local regulations and the scope of the project, it will probably be necessary to obtain a permit from your local zoning board prior to starting work and schedule an inspection of the completed structure. The contractor you hire will normally be the one to perform these tasks, although the homeowner is responsible for paying the fees, which will vary by location.
• Adding a deck or porch to your home increases its value and could affect the cost of your homeowner’s insurance premium, as well as your annual property tax bill. These costs can vary widely, depending on where the home is located and the value of the new construction.
• Maintenance requirements for a deck or porch in Canada are minimal and the costs are correspondingly low. An annual cleaning will set you back approximately $0.25-$1.50 per square foot. Wood decks should be sealed ($1-$5 sq. ft.) or stained ($0.50-$7 sq. ft.) every 1 to 2 years, depending on the type of wood used in construction and the amount of exposure to sunlight and weather it is exposed to.
