About Ontario

From weather to currency to measurements, here are a few helpful tips and things to keep in mind when travelling in Ontario. Plus, find some fun and interesting facts and information about the province. 

Currency and measurements

Currency, cash and credit

Canada’s currency is the Canadian Dollar. 

Major international credit cards, such as Visa and MasterCard are accepted by most businesses, some may only accept cashless transactions. It’s a good idea to carry some Canadian cash, a debit card and a credit card. Automated Teller Machines (ATMs) are located in banks and retail areas and dispense Canadian currency. 

A bank or currency exchange outlet can change your funds to Canadian dollars. Banks are generally open Monday to Friday, with some open on weekends. 

Familiarize yourself with the security features of Canadian banknotes to avoid counterfeit currency and use the Bank of Canada’s currency converter to view daily exchange rates.

Sales tax

Ontario has a 13% HST (Harmonized Sales Tax) that is applied to goods and services, purchased gifts and food/beverages. The HST is made up of a 5% federal tax and an 8% provincial tax. 


A tip of 15-20% at bars and restaurants is customary. Tips are also given to tour guides, taxi drivers, and for spa treatments and haircuts. Porters at airports, railway stations and hotels generally expect $1-2 per item of luggage.

Units of measurements

Canada uses the metric system for measuring distance, length, temperature, volume and weight, with units including kilometre, metre, litre and gram.  

Here’s a handy tool to help convert between imperial and metric units of measurement.

Weather in Ontario

Ontario's climate is considered continental, with temperatures ranging from humid in the south, with chilly winters and warm summers, to sub-arctic in the north. Due to Ontario's size, temperatures may vary tremendously from region to region.
