Greetings
When meeting someone for the first time in Canada, Canadians typically shake hands to introduce themselves. They may also shake hands before leaving. For women, in particular, brief hugs between close friends are becoming more popular. Although some French-Canadians might follow the European custom of delivering gentle cheek kisses as part of a friendly greeting, kissing is still primarily reserved for family or romantic partners. That is one of the the lists of Canada culture, customs, and etiquette.
When someone extends their hand to shake yours, it is regarded as exceedingly impolite and insulting to ignore them. It is typically only done when the other person has done something dreadful or is so well-known for being such a nasty person that it would be scandalous to greet them in a nice fashion. Refusing to shake is generally perceived as an overt sign of hate. However, the reverse is also true: shaking hands with a contentious person can be a sign of making peace or expressing acceptance.
