Ontario, Canada shapefiles projecting in the Mediterranean Sea (ArcMap)

Hello,

I am having a problem with purchased Ontario Base Mapping purchased from First Base Solutions projecting into ArcMap.

I began using the Mac-based GIS software called Cartographica to handle our purchased mapping. This mapping is required for a landscape architectural project located in Peterborough, Ontario. The files came without any projection assigned to them. I have attempted to set the map projection to WGS 84 and NAD 1983_UTM_Zone_18N. While the layers of the map align perfectly, the coordinates are way off.

I zipped the shape files and imported into ArcGIS online. The mapping appears in Vermont. We sent our shape files to a GIS expert, who informed us that when they imported our files into ArcMap, the map lined up exactly where it should be. He did not assign any projection or coordinate system to the shape files- he left them unprojected. See image for his result.

I downloaded a trial version of ArcGIS for Desktop. I imported the exact same shape files and added the topographic map as a base layer, and our files line up in the Mediterranean Sea. The layers are still currently unprojected.

Might anyone know exactly what I am doing wrong here? I would greatly appreciate any advice or assistance.

Thank you and hope to talk to you soon,
Katie
