Gingerbread Making Classes in Toronto?
Hiya - here's what I could find for you:
This place does school tours - maybe they'd do a custom lesson for you - or if not maybe they'd know somewhere that does?
This place in Concord sells kits & has pretty good instructions - maybe they'd know of a hands-on class?

Not exactly what you're looking for, but hopefully it'll give you some leads...
