In Canada this is the first male Erin I've come across so it's very rare here too.
According to the National Household Survey 2011, the Canadian population of Irish ancestry increased since the 2006 Census to stand at 4,544,870. The 4 provinces in Atlantic Canada recorded the highest % Irish descent. PEI topped the list at 29.2% of the population. Next was Nova Scotia (21.6%), Newfoundland and Labrador (21.5%), New Brunswick (21.0%), and Yukon (19.0%). All figures are from the 2011 Census. Nunavut Territory was lowest (4.2%) followed by Quebec (5.5%). Saint John, NB is usually cited as Canada's most 'Irish' city.
