Or is it that they want the .Com and not .CA?? Too bad they didn't want to use tatamagouche.com even after registering it. They also opted not to register villageoftatamagouche.ca.
There seems to be a real dislike for a .Ca by a village in Canada.
Well you're right that they seem to be leaning towards the .com since that's what their running with already, and they did previously own/use tatamagouche.com for a long time but seem to have let that drop sometime in 2010-2011.
So yep, definitely leaning towards the .com but I imagine they at least looked up tatamagouche.ca on a registrar like GoDaddy when they wanted to rebuild, saw it was "taken"/unavailable because it's restricted, and then moved on to another domain since they didn't know it was theirs to claim.
Would be crazy not to at least check for it (before choosing to go with their current domain), and even if they did check I would bet they'd have no idea it's reserved for them since there isn't any sort of indication it is... unless they knew to check the whois, read the info carefully, and then dig even further into it.
