I see 309a and 442a electricians doing each others work all the time and no one cares.This trade is not regulated in ontario.
According to ESA, a contractor IS NOT leagally allowed to send a 442a into the field to do electrical work. Ask any inspector and they will tell you that. This is what I mean by regulated.
Quoting "An employer can hire a bum off the street and put him to work as an electrician if they deem them COMPETENT as stated in the Ontario Heath and Safety Act." This is only true in a privatly operated operation such as manufacturing. These buildings are not accessed by the general public.
Only a 309a can leagaly work both!
