Does anybody know about Canada's culture? for example traditional, sports...

Traditions:

Canadian gift-giving tends to be relatively restrained. Some friends and families may exchange lots of expensive presents on symbolically essential days like birthdays or Christmas. In contrast, others may give only small ones, or none at all. Weddings tend to be the only events in which it is absolutely expected that every single person will provide a reasonably high-quality present.

Otherwise, Canadian standards of generosity tend to be the most personal thing. Canadians often wrap their presents in special decorative wrapping paper, but usually only if the gift will be given during some sort of party.

Sports (Most popular is Hockey):

Stereotypical though it may be, there’s no escaping the fact that Canadians really love their hockey. Forged in the early 19th century but popularized and structured as an acknowledged sport in the 1910s, hockey has held an outsized role in Canadian culture ever since.

To many, particularly those in the eastern part of the country, hockey has a heavily romanticized image as a rough-and-tumble game Canadians have played for generations on frozen lakes in the long winter months.

A sport whose ancient customs, duties, and traditions can be passed down teaches essential lessons about similarity, sportsmanship, teamwork, and athleticism.

Oldest team is Montreal Canadiens (est. 1917)
