So near the end of WWII Canada liberated  the Randstad,  (four largest Dutch cities Amsterdam, Rotterdam, The Hague and Utrecht) from German occupation. Which allowed Canada to send food aid to the many of dutch citzens who where suffering from the Hongerwinter (‘Hungerwinter’). The Netherlands were so thankful   for Canada’s help that they send Canada ten thousand tulips every year since the war which started the  Canadian Tulip Festival.
