Business Casual Means Two Different Things: Dress Codes in Canada vs. the UK

🇨🇦 Canada · 🇬🇧 UK

By Priya Mehta, The Global Office

Just 3% of Canadian finance departments now say their office requires a business suit, and in the UK, only 7% of workers report wearing "business attire" at all. Both countries are converging on the same casualized endpoint, but they started from very different places and are getting there at very different speeds — which matters enormously in the specific week you show up for your first day in the wrong outfit.

Do's & Don'ts

🇨🇦 Canada

🇬🇧 UK

Canada's shift toward casual has been fast and fairly broad-based. Indeed's hiring data shows mentions of casual dress in Canadian job postings have grown sharply since the pandemic and stayed elevated — 5.3% of postings referenced casual attire by mid-2025 — and Randstad's workplace research frames most Canadian offices as sitting somewhere between fully formal and fully casual, with the exact expectation shifting by company, industry, role, and even day of the week. The finance sector data is the clearest signal: 66% of Canadian CFOs describe their departments as "somewhat casual," and a mere 3% still require a suit. Analysts attribute much of the shift to the growing influence of Millennials and Gen Z moving into positions of authority, meaning the relaxation isn't just tolerance from the top — it's increasingly coming from the top.

The UK is relaxing too, but from a formal baseline that hasn't fully evaporated. Just 7% of UK workers now report wearing full business attire, but the country's dress-code landscape remains genuinely stratified: 32% of workplaces are casual, 20% smart-casual, 16% business-smart (suits and blazers expected), 12% fully relaxed, 12% smart, and 8% uniformed — meaning nearly a third of British workplaces still expect something close to formal wear. The pandemic-era casualization shows up clearly in job postings too, with mentions of casual dress in UK listings now more than ten times higher than pre-pandemic levels, per multiple 2025-2026 workplace surveys. But 74% of UK workers report their employer has a defined dress code at all, versus a much looser, more improvised norm typical in Canadian offices — the UK hasn't abandoned the concept of a dress code so much as loosened what sits inside it.

The Reckoning: Canada's relaxation looks like the removal of a rule; the UK's looks like the quiet redefinition of one. A Canadian company moving toward "dress for your day" is often making a genuine, unstructured bet that employees will self-regulate. A British company moving toward "smart-casual" is typically replacing one defined standard with another, still-defined standard — just a less starchy one. Practically, this means a Canadian newcomer to a UK office should expect more explicit rules than they're used to, even in a "casual" setting, while a British newcomer to a Canadian office should expect to have to infer the standard themselves, because there may not be one written down anywhere.

The Part the Brochure Left Out

Quora — Answering a question about cultural differences UK immigrants might not expect, one respondent said British people are noticeably "more formal" than Canadians in everyday interaction, a pattern they said extended directly into how people dressed and behaved at work.

Quora — Someone answering what the UK dress code for work actually looks like, and whether skirts are acceptable, described real variation by sector and seniority, noting that assuming a single national "UK style" undersells how differently a law office and a design studio in the same city can expect people to dress.

Quora — A respondent discussing casual dress codes more broadly observed that workplaces sometimes enforce a "business casual" policy on paper that leadership itself doesn't follow in practice, leaving newer employees to guess the real, unwritten standard by watching what senior people actually wear rather than what the handbook says.

teamblind.com — In a thread comparing dress norms across finance teams, posters described a common pattern: business casual as the day-to-day default, with an unwritten but firmly enforced switch to full suit-and-tie the moment clients are physically in the office — a distinction newcomers said wasn't spelled out anywhere until they got it wrong once.

Conclusion

If you're moving from Canada to the UK, over-dress slightly for your first two weeks and adjust downward once you've actually seen what your specific office and sector expect — the national trend toward casual doesn't mean your particular workplace has caught up to it. If you're moving from the UK to Canada, ask directly rather than assuming, because the absence of a visible dress code doesn't mean there isn't one, just that nobody's written it down. Priya's honest take: both countries are heading toward the same relaxed endpoint, but Britain is still finishing the paperwork on its casual Fridays while Canada already threw the paperwork out.
