in Canada, the first day of summer vacation for public schools is the Thursday before the last Friday of June. This may vary in Quebec (re earlier due to provincial June 24 holiday). In some areas, that Thursday is a half-day. The last day of summer vacation is Labour Day. It can vary in Private schools. School generally resumes the day after Labour Day (in September). Most have two weeks of vacation for Christmas and New Years, and a week for Spring Break (usually March).
Laatste vrijdag van juni dus.
