Canadians do not appreciate aggressive behavior or driving and have a low tolerance for shouting and public displays of affection.
Local* Perspective - Consistent with a strong sense of personal space and with protestant prudence, it is not that common to see Canadians displaying affection in public.
There is an implicit acceptance of ’positive yet neutral’ affection, for instance, old friends meeting after a long time, congratulations for achievements, etc. Yelling in public is uncommon, unless people are inebriated or having a fit of road-rage. In the event that there is scene of violence or someone is being attacked (verbally or physically), it is likely that the Police would be called to intervene. Canadians, in general, avoid conflict and confrontation and thus it is not common for people to intervene directly.
The rules for reacting and displaying affection and emotions are quite similar in offices (private or public sector). Decorum is highly valued and this implies limits on the types of displays of affection. The greeting is a handshake, irrespective of the rank or gender of the persons. Well-acquainted colleagues may permit themselves more open expressions of affection, including kisses on the cheeks (Canadians - if and when they kiss - usually would give two kisses, one on each cheek).
* Local designates a person born in Canada as opposed to a person of Canadian origin
Canadian Perspective - Canadians do not appreciate aggressive behavior or driving and have a low tolerance for shouting and public displays of affection. Many Anglophone Canadians are uncomfortable with strong demonstrations of emotions, particularly if it is with someone they do not know well. In Quebec or in many immigrant communities, emotions may be more freely expressed.
