Is fuel available at Waterloo Regional Airport?

The field is attended daily from 0500 to 2100 local time. Dispatchers arranging turnarounds outside that window should plan fuel requests accordingly, since availability outside attended hours is on request only.
What is the customs situation at KALO?

Crews requiring customs processing on an international itinerary need to route through that facility or another designated port of entry rather than clearing at Waterloo directly.
