Are cape Bretoners hostile to outsiders? (Specifically tradespeople)

EDIT: Thank you all for the responses and your opinions. For the most part, I'm quite happy it seemed to be more of an urban legend than rooted in reality. We're both calm, respectful, hardworking people. Definitely not the types to rub anyone the wrong way. The incident the may or may not have happened that I've described could probably be attributed to wrong personalities clashing as opposed to senseless xenophobia (if you can call it this way). I feel much more confident now.

We live in the HRM for the moment (originally from rural areas overseas), been looking at buying properties all over and considering the recent prices, Cape Breton seems to be like a decently attractive option. We've gone over for trips before (the hikes and trails) so it seemed nice enough. Until I spoke with some of my colleagues who said you'd better cross it off your list. See, my partner is a carpenter, he believes that these days he'd get a job anywhere, which does make things easier. However, when I told my colleagues that, they said he'd better watch himself as there were lots of cases of cape Bretoners beating up, stealing tools and even setting fire to structures of "outsiders" if he thinks he can start a business there as a carpenter. So far, I haven't found any news articles to support that claim, but apparently it's widely known in mainland construction companies not to send people there. Could anybody shed some light?
