Within any immigrant community, there will be a range of attitudes towards their new country (Canada) and its society and people and it's simply misleading to view such communities as some monolith in this regard.  It has always been so and throughout Canada's history, there have been immigrants that rued the day they arrived here and members of the broader Canadian society who greeted exotic newcomers with fear and anxiety.

Happily, over time both the newcomer communities and the general society have made common cause and acceptance and generally welcomed the enrichment of Canadian society that such a positive mutual accommodation has allowed.

The mid 19th century Irish weren't all active Fenians (even though a few were) you know.
