The ban was approved without debate at a meeting of the council of the European Union on Monday.
Demark and Romania abstained from backing the measure, which Ottawa has protested as an unfair trade restriction. Austria also abstained because it wants a stricter ban.
The restrictions would apply to all products and processed goods derived from seals, including fur, meat, oil blubber and even omega-3 pills made from seal oil. But the current ban exempts products from traditional hunts carried out by Inuit in Canada, Greenland, Alaska and Russia.
Another exemption will allow for non-commercial and "small-scale" hunts to manage seal populations. However, seal products derived from those hunts will not be allowed to enter the EU.
In May, members of the EU Parliament passed the bill for the ban by a 550-49 vote. The ban on the import to all 27 EU member countries is expected to take effect in October.
The European ban still allows Canada to ship seal products through Europe but it bars the promotion of the products.
"The government of Canada is gravely concerned that the European Union is continuing to push for a ban on seal products without any consideration of an exemption for Canada's humane and sustainable seal hunt," they said in a statement.
"The proposal currently being considered within the EU will serve no purpose other than to damage the livelihood of coastal and northern Canadians and their families."
Day and Shea threatened trade action against the European Union if it went ahead with the ban.
Government officials have not yet commented on the EU approving the ban.
The International Fund for Animal Welfare applauded the EU ban as a "significant victory." The organization has led a 40-year campaign to try to end Canada's commercial seal hunt.
"There is a wonderful sense of accomplishment today after years of hard work," said EU director Lesley O'Donnell.
Canada's East Coast seal hunt is the largest of its kind in the world, with an average annual kill of about 300,000 harp seals. Canada exported around $2.5 million worth of seal products to EU countries in 2008.
