I work as a Senior Data Scientist at Acosta, where I serve exclusively American clients. Thus, I like to block my holidays off with absences in my online work calendar. This prevents my clients from setting meetings with me on those days, and it also reminds me of upcoming holidays. For example, April 18 was Good Friday; it was a holiday in Canada, but not in the USA.
We have 10 provinces and 3 territories in Canada, and each jurisdiction has slight variations in its statutory holidays. Thus, I like to use a directory of holidays that specifically caters to Ontario, where I currently live. There is a website called statutoryholidays.com, and it has such a directory for every jurisdiction in Canada - including Ontario.
In Ontario, Remembrance Day is not a statutory holiday; it is a holiday for governmental sectors and federally regulated industries (like banking), but it is not a holiday for most private sectors. This is a unique situation that statutoryholidays.com highlights for Ontario. If you live in another province or territory, I encourage you to search for similar misalignments in your jurisdiction.
To my fellow Canadians: I encourage you to find all statutory holidays for your jurisdiction and mark yourself as absent on those days in your online work calendar.
