If you are going away during a Winnipeg winter, your sump pump may freeze and cause problems they are designed to prevent. Make sure you have someone checking your sump pump while you are away. It is important to keep your water flowing. Water flow is obviously not as heavy during the winter and if water is starting to ice up in the pit, adjusting the settings on the unit will help alleviate the problem. In Winnipeg where the land is flat, your discharge should be on a slope sufficient so that gravity keeps your water flowing.
