How much is $100 US in Canadian?

I'm curious to know, how much would the equivalent of $100 US dollars be in Canadian dollars? Given the fluctuations in the exchange rate, I'm looking for a general estimation of the conversion rate. Is there a specific tool or service you recommend for getting the most accurate and up-to-date conversion rates? Additionally, are there any factors I should consider, such as transaction fees or bank charges, that might affect the final amount I receive when converting US dollars to Canadian dollars?
