The verdict in three sentences
A successful site migration is not judged by the new design but by the preservation of organic traffic and Google rankings. Budget 40,000 to 120,000 CAD and 6 to 10 weeks for a clean migration, redirect plan included. The number one danger is the -25% to -40% traffic drop suffered by companies that neglect URL mapping and 301 redirects.
Budget and line items for a migration in Toronto
Here are the 2026 ballpark figures on the Toronto market, from design to SEO plan.
| Line item | Budget (CAD) | Timeline |
|---|---|---|
| Audit + URL mapping | 6,000 - 15,000 | 1-2 wks |
| Design + integration | 20,000 - 60,000 | 3-5 wks |
| 301 redirect plan | 5,000 - 18,000 | 1 wk |
| SEO QA + testing | 4,000 - 12,000 | 1 wk |
| Post-migration monitoring 4 wks | 5,000 - 15,000 | 4 wks |
| Migration total | 40,000 - 120,000 | 6-10 wks |
Add hosting with a CDN, between 400 and 1,500 CAD/month depending on traffic and the need for regional speed (North America + Europe).
SEO roadmap without ranking loss
Preserving SEO follows a strict sequence. Here is the estimated impact of each step on traffic-loss risk.
| Step | Action | Risk reduction |
|---|---|---|
| 1. Mapping | List 100% of active URLs | -40% risk |
| 2. 301 redirects | Map old to new URL | -30% risk |
| 3. Sitemap + robots | Resubmit to Search Console | -10% risk |
| 4. Tags + content | Keep title, H1, meta | -10% risk |
| 5. 4-8 wk monitoring | Fix detected 404s | -10% risk |
Applied fully, this sequence keeps traffic loss under 5%, usually recovered in 4 to 8 weeks. Skipping step 1 or 2 is the main cause of traffic collapses.
Mini case study
Mr. Carter, marketing director of a distribution group in Toronto, migrates a 250-page site generating 18,000 organic visits/month. Without a plan, a 35% drop would cost 6,300 visits/month; at 2% conversion and 80 CAD average order, that is roughly 10,080 CAD of revenue lost per month. He invests 85,000 CAD in a migration with a full redirect plan: real loss is limited to 4%, recovered in 6 weeks. The SEO plan surcharge (about 18,000 CAD) pays back in under 6 days of preserved revenue.

FAQ
How much traffic can we lose?
Between 25 and 40% without a redirect plan, versus under 5% with full mapping and clean 301s. The difference translates directly into revenue.
How long to recover rankings?
With correct redirects, 4 to 8 weeks. Google must re-crawl and re-index; a resubmitted sitemap and fixed 404s speed up the process.
Should we keep the same URLs?
Where possible, yes, it is safest. When the structure changes, each old URL must 301 to its closest equivalent, never just to the homepage.
What budget for the SEO part alone?
Between 15,000 and 30,000 CAD for mapping, redirects and post-migration monitoring on a mid-size site. It is the cheapest insurance in the project.
When should we migrate to limit impact?
Outside commercial peaks, ideally in a quiet period. Avoid high-activity weeks so any traffic turbulence is absorbed without critical revenue loss.
