As long as it is within Canada, yes. In most of the cases, you can use your service and your phone number when you travel domestically. Just connect your phone adapter to a high-speed internet connection at your new location, and you are good to go. All your calls will be treated the same way as if made using VMedia Home Phone at your home.
For example, if you are from Toronto, have a 416 number, and travel to Montreal, you can take your phone adapter with you, connect it to an internet connection there, and make calls as if you were still in Toronto; people will still be able to reach you at your 416 number, or you can call their 416 number, and neither party would be charged long distance.
