There is a national Reciprocity agreement under the Canadian Federation of Construction Safety Associations (CFCSA) that recognizes COR certification throughout the country.  Based on your COR status with another CFCSA Member, the NLCSA will issue a Letter of Good Standing for bidding purposes.  Once you are successful and start work in this province, you must contact the NLCSA to make arrangements to meet any additional, provincial specific, requirements and you must conduct an Internal Audit on your operations in this province.  Reciprocity Application forms are available online.  There is one form for companies registered in Quebec and another form for companies registered in the other provinces or territories – be sure to use the correct form.
