If you stay connected to Telus.... you should be fine.
Your Manitoba Telus packages should be good across Canada.
You can also make calls to local hotels and Sask friends in that local region with no extra charges. However if they call your Manitoba number... it will be treated as long distance.
If you are concerned... just sign onto your Telus Mobility account and change your usage information. It will show you if there are extra charges incurred. I check mine every second day when travelling in other countries to avoid surprises.
