Building Permit Fees: New Brunswick vs Ontario
Building permit fees in New Brunswick run significantly higher than Ontario for most residential projects, with New Brunswick charging $2,000 to $8,000 more for comparable work across major project categories.
The cost gap is most pronounced for major residential additions, where New Brunswick municipalities charge a fixed $8,000 while Ontario sources report $2,000 for the same scope of work. New home construction permits show similar disparities — New Brunswick ranges from $3,000 to $8,000 depending on complexity, while Ontario permits cost $2,000 to $8,000, clustering toward the lower end of that range.
| Project Type | New Brunswick | Ontario |
|---|---|---|
| Major residential addition | $8,000 | $2,000 |
| New home construction | $4,000–$6,000 (standard) $3,000–$8,000 (luxury) |
$2,000–$8,000 |
| Secondary suite conversion | $1,500–$5,000 | $1,500–$5,000 |
| Garden suite/coach house | $2,000–$8,000 | $1,500–$5,000 |
| Basement finishing | $400–$600 | Not available |
| Kitchen renovation | $600–$1,200 | Not available |
Secondary dwelling unit permits show closer alignment between provinces. New Brunswick charges $1,500 to $5,000 for basement apartment conversions, matching Ontario's $1,500 to $5,000 range. However, New Brunswick's garden suite permits reach $2,000 to $8,000, while Ontario's coach house permits cap at $1,500 to $5,000.
Why New Brunswick Costs More
The fee differential stems from municipal capacity constraints and regulatory complexity in New Brunswick's smaller jurisdictions. Unlike Ontario's streamlined building departments in major cities, New Brunswick projects often flow through Regional Service Commissions that serve multiple communities with limited specialized staff.
New Brunswick's extreme climate conditions drive more rigorous permit review processes. Projects must account for 5-6 foot frost depths, heavy snow loads, and coastal salt air corrosion — factors that require additional engineering review time compared to Ontario's more temperate southern regions. The NB Building Code incorporates these climate-specific requirements, but smaller municipal building departments lack the volume efficiency of Ontario's Toronto or Ottawa building divisions.
Technical Safety Authority of New Brunswick handles both electrical and gas safety oversight, creating coordination requirements that don't exist in Ontario's split system between ESA and TSSA. This consolidated approach can streamline some approvals but often extends initial permit processing times, particularly for complex residential additions requiring multiple systems integration.
The higher permit fees also reflect New Brunswick's smaller construction market. Where Ontario building departments process hundreds of applications monthly, New Brunswick municipalities handle dozens, spreading administrative overhead across fewer projects. WorkSafeNB and Consumer Protection Act compliance adds documentation requirements that increase processing costs per application.
The Bottom Line
Ontario delivers significantly better value on building permit fees, particularly for major residential work. The $6,000 savings on a major addition permit alone covers substantial project costs elsewhere. However, New Brunswick's higher fees often include more comprehensive plan review and inspection services, reflecting the province's emphasis on cold-climate construction compliance.
Homeowners planning major renovations should budget $3,000 to $5,000 more for permit costs in New Brunswick compared to Ontario. For smaller projects like basement finishing or kitchen renovations, New Brunswick actually offers competitive rates at $400-$1,200, where Ontario data is limited. The key is matching project scope carefully — New Brunswick's higher fees typically correlate with more thorough regulatory oversight in challenging Maritime conditions.
