Web Application Development in Canada

About Web Application Development

We build custom web applications from Noida, Delhi NCR: customer portals, booking and quoting systems, dashboards, marketplaces, and SaaS products on Next.js and React with a Node.js or Laravel API and PostgreSQL. You work directly with the senior engineers writing your code, get a written scope, and a flat quote back in 24 hours.

What the engagement includes

• Senior engineers on your app from day one. You talk to the people writing the code, not an account manager or a junior swapped in after the sale.
• A written scope before any code and a flat quote inside 24 hours, so the price is set before we start and does not move unless the scope does.
• A data model and roles designed up front, so the app holds up as you add features instead of collapsing under its own weight.
• Tests and CI in the build, not bolted on later. Every push runs the suite before it deploys.
• You own everything: the code, the repo, and the AWS hosting. Nothing is locked to us and you can walk with all of it at any time.
• For overseas clients we quote in flat INR and can invoice in USD, CAD, GBP, or AED through Wise, with W-8BEN and LUT on file.

A Quebec privacy assessment, Ontario's e-signature rules and six years of CRA records in a Canadian web application

In Quebec the decision to build a web application is itself a regulated event. Since 22 September 2023, section 3.3 of the Act respecting the protection of personal information in the private sector has required an enterprise to carry out a privacy impact assessment for any project to acquire, develop or overhaul an information system or electronic service delivery system that involves collecting, using, communicating, keeping or destroying personal information, and to consult its person in charge of the protection of personal information from the start of the project. The Commission d'accès à l'information's guide to these assessments, version 3.1 of April 2024, gives a members' area of a website and an electronic file as examples of electronic service delivery, and a case management system and a payroll system as examples of information systems, which takes in most of the customer portals, booking systems and internal dashboards we are asked to build. Two details in that guide shape the engagement. The assessment belongs to the organisation holding the information, not to its subcontractors or suppliers, who can help with the analysis, so it is yours to sign and ours to feed. And an overhaul counts as much as a new build, so replacing an ageing portal triggers it even when the data stays the same. The Act scales the assessment to the sensitivity, purpose, quantity, distribution and medium of the information, so a staff rota and a patient portal do not warrant the same document. What we supply is the factual half, the part a privacy officer finds hardest to get out of a vendor: a field-level inventory of what each form collects and why, a diagram of where each record travels, including every third-party API and the region it runs in, who can read it in the admin, and how long it lives. That arrives in the first sprint, because the assessment is meant to be able to change the design, and it cannot once the schema has shipped. Whether the Act applies to your enterprise, and how deep the assessment has to go, is for your privacy officer or counsel.

Many Canadian web applications end in a signature, on an application, a lease, a consent or a work order, and in Ontario the Electronic Commerce Act, 2000 decides what that signature can carry. It defines an electronic signature as electronic information a person creates or adopts in order to sign a document and that is in, attached to or associated with the document, and section 11 says a legal requirement that a document be signed is satisfied by one, subject to reliability and method requirements for documents prescribed by regulation. Two limits matter more in practice. Section 31 takes some documents out of the Act altogether: wills and codicils, trusts created by them, powers of attorney for an individual's financial affairs or personal care, negotiable instruments and, apart from contracts for the carriage of goods, documents of title. And section 29 says the Act does not apply to biometric information used as an electronic signature unless another Act provides for it or all parties to the transaction expressly consent, which matters the moment someone proposes signing with a face scan or a fingerprint. The Act also makes electronic documents optional, though consent can be inferred from conduct, and a legal requirement to give someone a document in writing is met electronically only if the document is accessible for later reference and capable of being retained by them. For the application that means the signing step records who signed, how they were authenticated and exactly which version of the document they saw, and freezes the signed file with a hash rather than regenerating it later from a template that may have changed. A document type flag routes the excluded documents, a power of attorney for instance, to a paper path instead of the signing flow. Signing with a fingerprint or a face is offered only behind an express consent step. And every signed document is delivered as a file the person can download and keep, not only as a page behind their login. Whether a particular document needs more than this is for your own counsel.

The retention period imposed by law is where federal tax rules come in, and for anything that records a transaction they pull the other way. If the application is where your orders, invoices, payments or payroll entries live, it holds books and records under section 230 of the Income Tax Act, which have to be kept for at least six years from the end of the last tax year they relate to, and subsection 230(4.1) requires records kept electronically to be retained in an electronically readable format for that period even when a paper copy exists. The CRA's circular on electronic record keeping, IC05-1R1, says records must be kept at the person's place of business or residence in Canada or another place the Minister designates, that records kept outside Canada and accessed electronically from Canada are not considered records in Canada, and that permission to keep them elsewhere is granted in writing on the Minister's terms. It tells internet businesses hosted on a server outside Canada that the duty to keep records in Canada applies to them too, recommends keeping backup copies in Canada, and says a change to the business system must not cause the loss, destruction or alteration of information relevant to the tax payable. That last line is the one a rebuild trips over. Moving to a new application means six years of history in the old one either migrates intact and readable or stays retrievable somewhere, and a new schema whose records begin on launch day quietly fails it. So we host the primary database and its backups in a Canadian region, build the migration to carry closed transactions as well as open accounts, and write the retention schedule so an invoice survives its six years while the marketing profile attached to the same customer is purged when its purpose ends. Whether any part of your setup needs the Minister's permission is for your accountant.

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.
