Healthcare Software Development Company in Toronto, built to ship.

Patient identity is the hardest problem in the building

Two records for one person is the defining healthcare data failure, and it happens through a misspelt name, a changed surname, a transposed date of birth. Once duplicated, a clinician sees half a history and does not know it. Master patient index and matching rules belong in the first architecture conversation, not in a later data-quality project.

Interoperability is the requirement behind the requirement

HL7 v2 is still everywhere and FHIR is what everything new expects, so most real systems speak both and translate between them. The translation layer is where the effort goes, because the two models disagree about how much structure a clinical fact has.

Audit is not logging

Who viewed which record, when, and under what justification. Access logging in healthcare is a legal artefact that gets read by an investigator, so it has to be immutable, queryable and complete, which is a different design from application logs that rotate away after thirty days.

Every field is a clinical safety decision

A dropdown that permits an implausible dose, a date picker that accepts a future birth date, a free-text field where a coded value was needed. Validation here is not input hygiene, it is the difference between a caught error and a delivered one.

Working overlap

1.5 hours a day

Ten and a half hours behind Surat, which leaves roughly ninety minutes of shared working day at the very start of theirs and the very end of ours. This is the hardest overlap on the list and it has to be designed for: written handover, decisions batched, and one fixed call rather than ad hoc availability.

The law that applies

PIPEDA federally, with Quebec's Law 25 applying to Quebec residents

Law 25 is materially stricter than PIPEDA on consent and on automated decision-making, and it applies based on where the individual is, not where the company is. A Toronto client with Quebec customers inherits it, which surprises people.

Procurement

Documented and reference-led. Residency questions come up more often than in the US.

Language

English for Toronto, but French is a legal requirement for anything serving Quebec, and that is a build consideration rather than a translation line item.

Where the data can live

Azure Canada Central and Google northamerica-northeast2 are both in Toronto, and AWS ca-central-1 is in Montreal. Canadian clients ask about residency more often than American ones, and public sector work frequently requires it outright.
