Yes, I think that’s the plan. One of the problems–and I just covered the new harmonization rules–is that I don’t have access to the doggone CSA Z1220 standard. But I believe that part of the first aid harmonization is to establish Intermediate and Advanced First Aid Attendant as the standard. I believe all 4 of the provinces you name have already done that and are providing employers a grace period (1 year mostly, but I think it’s shorter in Quebec) to make the transition from Level 1/Level 2 to Intermediate/Advanced and are recognizing Level 1/Level 2 as equivalent in the interim.
Just FYI, I actually had the same question, but with regard to first aid needs assessment rather than first aid attendants. For example, in some provinces the trigger for requiring a first aid room is 100 workers per shift and in others it’s 200. Wonder if they’re gonna harmonize that. Maybe you can tell me. Have a great weekend and I hope this helps.
