The verdict in three sentences
For the CIO of a Toronto services group dealing with plugin vulnerabilities and slow WordPress pages, moving to Next.js with a headless CMS costs 15,000 to 45,000 CAD excl. tax for 50 to 300 pages, plus 2,200 to 6,000 CAD for 301 redirects and SEO recovery. The project runs 8 to 14 weeks, and a poorly prepared migration temporarily loses 5 to 15 % of organic traffic. If your site has fewer than 30 pages, few contributors and no strong performance requirement, simply hardening WordPress (3,000 to 7,500 CAD) remains the more rational decision.
Migrate or harden WordPress: the numbers side by side
WordPress is not a bad tool. The problem usually comes from accumulation: 30 to 50 plugins, a page builder, postponed updates and shared hosting. The question is whether fixing that stack costs less over three years than leaving it.
| Criterion | WordPress hardening | Next.js + headless CMS migration |
|---|---|---|
| Upfront investment | 3,000 to 7,500 CAD | 15,000 to 45,000 CAD |
| Attack surface | Reduced, but plugins still exposed | Static or server-rendered public site, separate back office |
| Security updates | Weekly, 2 to 4 h per month | Quarterly front-end dependencies, 1 to 2 h per month |
| Mobile performance (LCP) | 2.5 to 3.5 s after optimisation | Typically 1.2 to 2 s |
| Recurring cost | 120 to 375 CAD/month (hosting + maintenance) | 0 to 450 CAD/month CMS + 30 to 225 CAD/month hosting |
| Content team autonomy | High, familiar interface | High after 1 to 2 days of training |
| 3-year total cost (order of magnitude) | 10,500 to 22,500 CAD | 21,000 to 60,000 CAD |
Migration is justified when the site is a strategic asset: several brands or subsidiaries, bilingual English and French content for Canadian audiences, CRM or ERP integrations, or security requirements from an audit or a major client.
Detailed migration budget in Toronto
Toronto agencies charge 850 to 1,150 CAD per day in 2026 for this kind of project. Cost depends less on page count than on the number of templates and the quality of existing content.
| Work package | 50 pages (CAD) | 300 pages (CAD) |
|---|---|---|
| Audit of existing site, URL and content inventory | 1,200 | 3,000 |
| Content modelling in the headless CMS | 1,800 | 5,200 |
| Next.js development (templates, components, search) | 7,500 | 19,500 |
| Automated content and media migration | 1,500 | 6,800 |
| Integrations (forms, CRM, analytics, consent) | 1,500 | 5,200 |
| QA, accessibility (AODA), performance | 1,500 | 5,300 |
| Migration subtotal | 15,000 | 45,000 |
| 301 redirect plan, SEO recovery, 3-month monitoring | 2,200 | 6,000 |
Risks to neutralise
- Traffic loss: a complete inventory of indexed URLs, 301 redirects tested one by one, title and meta tags carried over, sitemap submitted on launch day. Without this, the drop can exceed 30 %.
- Orphaned content: page builder shortcodes and proprietary blocks that do not migrate automatically. Plan 10 to 20 % of manual rework.
- Vendor lock-in: require the source code in your own Git repository, documentation and a CMS account you own.
- Forms and tracking: every form must be retested with the CRM, or you lose leads without noticing.
Mini case study
Daniel, CIO of a Toronto business services group (600 staff, 4 subsidiaries), runs a 180-page WordPress site with 42 plugins. In 18 months he has had two security incidents, each costing about 9,000 CAD (emergency contractor, clean-up, internal time), and pays for 3 hours a week of maintenance at 105 CAD per hour, about 16,400 CAD a year.

He approves a 33,000 CAD migration plus 4,500 CAD of SEO recovery, with 225 CAD per month of headless CMS and 135 CAD per month of hosting. Maintenance drops to 1.5 hours a month, i.e. 1,890 CAD a year. Annual saving: 16,400 - 1,890 - 4,320 of running costs = 10,190 CAD, plus 6,000 CAD a year of avoided incidents on average, i.e. 16,190 CAD per year. The 37,500 CAD investment pays back in about 2.3 years, before any conversion gain from LCP dropping from 3.9 s to 1.6 s.
FAQ
How much does a WordPress to Next.js migration cost in Toronto in 2026?
Budget 15,000 to 45,000 CAD excl. tax for 50 to 300 pages, plus 2,200 to 6,000 CAD for redirects and SEO recovery. Template count and existing content quality matter more than page count.
Will we lose traffic?
A temporary 5 to 15 % drop over 4 to 8 weeks is common, even with good preparation. With a complete redirect plan, traffic usually returns to its previous level within 2 to 3 months.
Which headless CMS should we pick?
Sanity, Strapi or Payload cover most corporate needs for 0 to 450 CAD per month depending on editors and projects. Strapi and Payload can be self-hosted in Canada, useful for data residency requirements.
Will communications teams lose autonomy?
No, as long as the CMS is modelled around their real workflows with reusable blocks. One to two days of training is usually enough.
When is it better to stay on WordPress?
Under 30 pages, with a single contributor and no complex integration, hardening at 3,000 to 7,500 CAD plus serious maintenance remains more cost-effective over 3 years.
