Declaration of marital status in Canada
The Netherlands embassy in Ottawa, the consulate-general in Vancouver and Toronto do not issue this declaration.
We suggest you contact the Canadian provincial or territorial authorities and request a (negative) "search of marriage" or you request a Statement in Lieu of Certificate of Non-Impediment to Marriage Abroad from Canadian Global Affairs.
