Node.js Development in Canada

About Node.js Development

Our Node.js development services cover the backend a product actually runs on: REST and GraphQL APIs, real-time features, mobile app backends and custom Node.js application development, all in TypeScript. Node.js is our default backend choice when a project needs speed-to-ship, real-time features, or a single language across the stack. We've built Node.js backends for SaaS dashboards, mobile apps, multi-tenant platforms, and real-time collaboration tools, using NestJS, Express, or Fastify depending on what fits the team and scale. Proper testing, observability built in, and deployment automated from day one.

What the engagement includes

• REST API development (Express, Fastify, NestJS)
• GraphQL API development (Apollo Server, Pothos, Yoga)
• Real-time backends (Socket.IO, native WebSockets, server-sent events)
• Microservices architecture and service mesh (NATS, RabbitMQ, gRPC)
• Authentication systems (JWT, OAuth 2.0, Auth.js, Clerk)
• Database design and ORM setup (Postgres, MongoDB, Prisma, Drizzle)
• Background job systems (BullMQ, Agenda, Trigger.dev)
• Third-party API integrations (Stripe, Razorpay, Twilio, SendGrid)

What Canada's open banking law, the RPAA and the federal API standards change in a Node.js backend

Canada's open banking regime is now law and not yet usable, and a Node.js product that wants bank data has to be built for the gap between the two. Bill C-15 received Royal Assent on 26 March 2026 and replaced the 2024 Consumer-Driven Banking Act with a new Act supervised by the Bank of Canada rather than the FCAC. The proposed regulations were pre-published in the Canada Gazette on 27 June 2026 with comments closing on 26 August, and the summary of the advisory committee meeting of 21 July targets final regulations for late 2026 or early 2027, coming into force in stages that start with accreditation. Data sharing is to be phased by product, deposit and payment accounts before lending and investments, and the first phase is read only. Write access, letting a customer switch accounts or pay bills through your product, is something the government has committed to legislate by mid-2027, once the Real-Time Rail is live and in wide use. Participating banks will have to implement a single technical standard set by a body the Minister designates, and no body had been designated at the July meeting. Third parties will need accreditation from the Bank of Canada, national security screening included, with a streamlined route for payment service providers already registered under the RPAA. The ban on screen scraping is written into the framework but will not come into force until it is fully operational. So the integration you can ship today probably runs through an aggregator using whatever access each bank allows, and the one you will need later runs on a standard nobody has published. We put both behind one adapter in the Node service, keep each customer's consent with its scope and expiry as a record of its own, and keep write features off the roadmap until the law that permits them exists. Whether and when to seek accreditation is for your own counsel.

If the platform holds money for its users or moves it at their request, the Retail Payment Activities Act may make you a payment service provider supervised by the Bank of Canada, and that turns on what the backend does rather than on what the company calls itself. The Act lists five payment functions: providing or maintaining an account held on behalf of end users, holding funds until they are withdrawn or transferred, initiating an electronic funds transfer at an end user's request, authorising or transmitting transfer instructions, and clearing or settlement. A marketplace that keeps sellers' balances and pays them out on request can perform three of those. The Act reaches functions performed as a service or business activity that is not incidental to another one, and it does not apply to an agent of a registered provider acting within its authority and named on that provider's list of agents, which is one reason so many platforms route funds through a registered processor. Registration began on 1 November 2024, and the requirements for a risk management and incident response framework and for safeguarding end users' funds came into force on 8 September 2025. Section 18 carries an engineering duty: a provider that becomes aware of an incident with a material impact on an end user must notify that end user and the Bank without delay. Meeting it takes detection, a way to list exactly which users were affected and a notice path built before anything goes wrong, not a status page. Bill C-15 also adds a sixth function, transmitting or maintaining an end user's tokenised payment instrument or private key, not yet in force in September 2026, so a backend that keeps stored cards or keys for its users should be drawn with that function in view. Whether your design makes you a provider, an agent or neither is for your counsel to decide on the ledger as drawn, which is why we draw the ledger first.

Selling an API or an integration to a federal department brings a published specification that is unusually concrete. The Government of Canada Standards on APIs, which the Directive on Service and Digital requires departmental initiatives going to the GC Enterprise Architecture Review Board to align with, ask for RESTful JSON by default, TLS 1.2 or later, OpenID Connect and OAuth 2.0, JSON Web Tokens that expire in under 24 hours, API keys in a header rather than the URL, UTF-8 with ISO 8601 dates in UTC, semantic versioning with only the major version in the path and the previous version still supported, and an OpenAPI description published to the GC API Store. The clause that changes a Node codebase most is the official languages one. An external API has to read the Accept-Language header and reply in English or French as asked, so validation errors and messages come from a catalogue in both languages rather than from strings typed into a NestJS exception. For notifications, GC Notify is the Canadian Digital Service's email and text message service for federal services, and it has no Node client of its own: its documentation points to the GOV.UK client with the API endpoint changed. Test keys deliver nothing, team and safelist keys reach only listed recipients while a service is in trial, live keys exist only once it is live, and each key type is limited to 1,000 requests a minute, so bulk sends go through a queue that respects that rather than a loop. If the buyer is a bank, a telecom carrier or another federally regulated operator in a vital sector, Bill C-8 received Royal Assent on 15 June 2026, and once its Critical Cyber Systems Protection Act part is brought into force a designated operator must identify and mitigate the risks in its supply chain and its use of third-party products and services, which reaches a vendor's dependency tree and access model. Whether you are designated is for your counsel.

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.
