To answer your question, your husband would apply to NSRP as an entry level applicant.
https://www.ns-rp.ca/applicants/those-not-registered-as-psychologist-elsewhere/nWhile the Regulated Health Professions Act and the Psychology Regulations requires 2 years of supervision, there is a clause so that the NSRP can provide full credit for the internship year, so the individual should only have to complete one year of post doctoral supervision while on the Register of Candidates. This means that for registrants with a doctoral degree, typically a minimum of 2 hours per month of supervision for a period of 1 year (for a minimum of 1500 hours of practice) is required because a year’s credit has been provided for the internship.
The NSRP requires the EPPP & Oral Exam. These exams are taken after the individual is placed on the Register of Candidates.
