Prices vary by region, so unless someone here knows the prices in Winnipeg, there's no way anyone is going to know the cost. You need to contact an installer and ask them for a quote. Don't go through Rona or any other big box store, contact an actual flooring installer (you may have trouble finding anyone who will install in a trailer). Rona at all are just a middle man and you will paying more to have them look after the work. Laminate is pretty easy to install and you could probably do it yourself.
