In the press release for the Eid stamp in May was this announcement:

Canada Post has issued annual Christmas stamps since 1964. In recent years, one Christmas stamp has depicted a sacred image reflecting the Christian faith, and another reflects a secular holiday theme.

Earlier this year, Canada Post and India Post agreed on a historic joint stamp issue featuring two stamps marking Diwali, the Hindu festival of lights. One stamp from each country will be released on the same day in the fall of 2017. Canada Post had also announced earlier that it will issue a Hanukkah stamp this year, recognizing the Jewish faith’s eight-day celebration in December, which commemorates the rededication of the Temple in Jerusalem in the second century B.C.E.

Together the Eid, Diwali and Hanukkah stamps build on the tradition of Christmas stamps and depict our pride in Canada being a land of diverse faiths, customs and celebrations.
