◊ travel essentials

Crossing the border. Money, language, plugs.

Money changes hands at the border: Ottawa uses the CAD ($) and Antananarivo uses the MGA (Ar). Conversations can stay in French, which is official in both countries. Cars drive on the right in both, so rentals feel familiar.

◊ common questions

Quick answers. Before you book the call.

What's the time difference between Ottawa and Antananarivo?

Ottawa is 7 hours ahead of Antananarivo. Ottawa runs on GMT-4 and Antananarivo on GMT+3. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.

When's the best time to schedule a meeting?

There are 1 hour where both cities are inside a 09:00–17:00 workday. Aim for the middle of that window so neither side is starting or closing out.

Does daylight saving time change the difference?

Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.

How far is Ottawa from Antananarivo?

About 14,061 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 17h 3m, not counting airport time, winds, or routing around restricted airspace.

Can I send this meeting time as a calendar invite?

Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.

What currency do Ottawa and Antananarivo use?

Ottawa uses the Canadian dollar (CAD, $); Antananarivo uses the Malagasy ariary (MGA, Ar). Check the live rate before transferring money or paying with a card abroad — most banks add a 1–3 % FX margin on top of the mid-market rate.

How do I call Ottawa from Antananarivo?

Dial the international prefix used by your carrier (often 00), then +1, then the local number — drop any leading zero of the city or mobile code. For free calls, WhatsApp, Signal, and FaceTime work over Wi-Fi regardless of country code.

What language is spoken in Ottawa and Antananarivo?

Both Canada and Madagascar count French among their official languages, so business meetings often skip translation. Ottawa also has English; Antananarivo adds Malagasy.

Do Ottawa and Antananarivo drive on the same side of the road?

Yes — both drive on the right. Rental cars feel identical between the two.
