Yup,...Corrections is different.
I guess it is.
From what we were told, CF time does not apply towards the EMS-ESM:
"Those with at least 10 years of service with emergency medical services may include, in the 20 years of service, service completed in
another profession, provided this service has not been recognized by another long service, good conduct or efficiency decoration or medal awarded by the Crown."
We asked Ottawa what they meant by "another profession". They said it had to be one of the professions in the Exemplary Service Medal "family" ( as they called it ).
