If you mean "Combat Engineers" vice "construction engineers", 2 FER is located in the Denison Armoury:
Postal address:
2 Field Engineer Regiment
The LCol George Taylor Denison III Armoury
PO Box 5000
Downsview, ON M3M
Street address:
1 Yukon Lane, Downsview (North York) - one street WEST of Dufferin/Allen Road, off Sheppard
(there are two Shermans and some Bailey bridge on the front lawn, across from the Esso)
(same location as ASU Toronto, if you're talking "CE"/construction engineering, although I think it's largely ASD/contracted out ... which means fewer troops on pde ... or aval for duties ...)
