Ottawa Business Pulse

  • Culture Formal, professional, and influenced by government and high-tech industries.
  • Lunch Break 12:00 PM - 1:00 PM.
  • Pro Tip Ideal call window is 9:30 AM to 11:30 AM. Ottawa is the capital of Canada; expect high professional standards and formal protocols. It is also a major tech hub. Punctuality and clear communication are highly valued. Avoid calling late on Friday afternoon.

Sydney Business Pulse

  • Culture Relatively relaxed but professional. Early starts are common to maximize daylight.
  • Lunch Break 12:00 PM - 1:00 PM.
  • Pro Tip Due to the significant time difference with Europe and the US, early mornings (8:30 AM - 10:00 AM) are often dedicated to international syncs. For domestic calls, late mornings are best. Be mindful that many Australians start and end their day earlier than their Northern Hemisphere counterparts.
