A quick workaround for this issue on earlier Unity version is to do this in the first frame, which forces the component to update:
foreach (var arf in gameObject.GetComponentsInChildren<AspectRatioFitter> ()) {
var restore = arf.aspectRatio;
arf.aspectRatio = arf.aspectRatio*1.001f;
arf.aspectRatio = restore;
}

This particular issue appears to be fixed in 2017.3.1p4. However, there is still another closely related one:
When SetActive(true) is called on a previously disabled canvas during a Update() or LateUpdate() event from another script, the RectTransform is not recalculated until next frame. The symptom is the same as this one (incorrect RectTransform dimension for one frame).
