To get to the Fletcher Wildlife Garden Interpretive Centre, take the unpaved road on the east side of Prince of Wales, between the traffic circle and the red barn. Don’t search for it on Google Maps, because you’ll end up in a field. Instead, zoom in on this map — the Interpretive Centre is at the end of the dirt road, exactly at the red marker:

FWG is next to the Arboretum at the Central Experimental Farm, and within walking distance of the Carling O-Train station or Carleton (cross at the Hartwell Locks).
