Ottawa weather in October is cold and rainy. The sun will occasionally show itself. The average maximum daytime temperature lies around 13.0°C (55.4°F), the lowest (minimum) average temperature at night is 4.0°C (39.2°F). So plan on bringing your warm clothes, it can be a bit chilly during this period.


The Canadian Dollar (sign: $; code: CAD) is the currency of Canada. International credit cards, such as American Express, Diners Club, MasterCard, and Visa credit cards, are all widely accepted in Canada. Exchange offices and ATM machines are available throughout Canada.

The official currency of the congress is the Euro (€).

For exchange rates:


Canada is divided to several time zones. Ottawa uses EDT — Eastern Daylight Time (GMT -4 hours) between March to November. Between November to March it is Eastern Standard Time (EST). So during SIOP 2023 the time zone will be EDT — Eastern Daylight Time (GMT -4 hours)
