Next.js Development in Canada

About Next.js Development

Next.js is our default for any modern web project where SEO, performance, and developer experience all matter. We've shipped 8+ production Next.js apps on the App Router across SaaS dashboards, headless e-commerce, content sites, and marketing pages, including this one. Every build uses TypeScript, Tailwind, and the latest Next.js patterns, deployed to Vercel for the fastest possible iteration loop.

What the engagement includes

• Next.js 16 (App Router) custom application development
• Headless Shopify storefronts on Next.js
• Headless WordPress front-ends on Next.js
• Multi-region SaaS dashboards with auth (Clerk, Auth.js)
• Server Actions, Suspense boundaries, and streaming SSR
• Static export sites for content / marketing
• TypeScript-first codebases with strict mode
• Migration from Pages Router → App Router

What Quebec's language rules and Canada's debit rules change in a Next.js build

If the product is sold into Quebec, the Charter of the French language reaches further into a Next.js application than its marketing pages. Since 1 June 2022, section 52 has covered order forms and similar documents offered to the public whatever the medium, section 57 covers invoices and receipts, and neither may be given in another language unless the French version is available on terms at least as favourable. In Next.js development the checkout, its error messages and the receipt are where that usually fails, and the cause is the framework rather than the translator. The Pages Router had locale routing built in, set the lang attribute on the html element and remembered a visitor's choice in a NEXT_LOCALE cookie. The App Router dropped all three, the migration guide's own root layout hard codes lang="en", and a French page declared as English is read by a screen reader with English pronunciation rules. The root params getter that hands the locale to Server Components also does not run in Server Actions or Route Handlers, so a form validated in an action and a receipt sent from a payment webhook have no URL to take the language from and fall back to English. We store the language on the account and pass it into both explicitly. How far section 52 reaches into your product is a question for your counsel.

The sign-up screen carries a second Quebec obligation that starter templates rarely handle, because the terms a customer accepts there are usually a contract of adhesion. Since 1 June 2023, section 55 of the Charter has required the French version of such a contract to be remitted to the adhering party before anyone can be bound by a version in another language, and then only if that is their express wish. No charge may be made for the French version, and a customer who seeks to annul the contract for a breach of section 55 does not have to prove injury. The Office québécois de la langue française says that for a contract concluded by technological means, the duty is met when the French standard clauses are remitted, or when the platform is available in French and the French contract is accessible on it. In a Next.js build that turns a checkbox into a data model. The terms live as versioned documents in both languages rather than as one page in the English tree, the Server Action that records acceptance writes which version, which language and when, and a customer who prefers the English terms sees the French first and makes that choice as a separate, recorded step. Whether your terms are a contract of adhesion, and whether a customer outside Quebec changes the answer, is for your counsel.

Subscription billing is where Canadian buyers ask for something a card-first checkout was never built for: pre-authorized debit from a bank account, governed by Payments Canada's Rule H1. The rule wants a PAD agreement carrying its mandatory provisions and coded as personal or business, and the coding matters, because a payor can claim reimbursement of a disputed personal debit for up to 90 calendar days and a business one for only 10 business days. A confirmation is due at least 10 calendar days before the first debit, or within 5 calendar days after it where the payor has waived that; each variable amount debit after the first needs 10 calendar days' notice of its amount and date, subject to the rule's exceptions; and the agreement and evidence of authorization are kept for at least 12 months after the last debit. So the notice schedule is a backend job, not an email template. If the processor is Stripe, two limits shape the Next.js code before the design does: its Payment Element does not support PAD in deferred-intent integrations, where the intent is created only on submit, and Stripe Checkout does not take PAD in subscription mode. A debit can also take up to five business days to confirm, so the account page needs a processing state that says so. Your processor or bank confirms which of these terms bind you.

How we work with Canadian clients

Two things shape Canadian projects more than anything technical. The first is language: if you serve Quebec, French is a legal requirement rather than a nice addition, and the rules tightened considerably under Bill 96. The French version has to be available on equal terms with the English one, which is a design constraint from the first wireframe rather than a translation task at the end.

The second is anti-spam law. CASL is stricter than most teams expect, and the penalties are real. Consent has to be express or clearly implied, records of it have to be kept, and every commercial message needs a working unsubscribe and accurate sender identification. We build those into the product rather than leaving them to whoever configures the mailing tool later, because that is where the exposure usually sits.
