Hi Brad,
I've worked in ocean transport for years.Atlantic Container Line(ACL) ship out of Southhampton and sail directly into Halifax,close to you.Their ships are roll-on/ roll-off capable.Depending on the weight/measure of the ferret(L x W x Ht) or weight,this will affect the shipping charge.There will also be a handling charge for handling and discharging this end when you pick it up at the pier.This is cheaper because you would have to pay an additional inland transport fee to bring it to Truro.Call the local ACL office in Halifax and they'll be glad to help.Good luck on the purchase.
