Geoff;
Canadian Sappers at the Driel site were: 23rd Canadian Field Company, R.C.E. and an engine and boat maintance party from 3rd Electrical and Mechanical Platoon (Type 'A'), R.C.E. (from 10th Canadian Field Park Company). Note: all the above assets from 1st Canadian Army Troops, R.C.E.

Hope this answers your question Geoff.
Cheers
