What do you mean by "National Holiday"?
Do you want it recognized and proclaimed a holiday by the federal government? Well, it already is. See
Holidays Act R.S.C., 1985, c. H-5
Or is your complaint that you live in a province where you do not automatically have the day off with pay to do as you please? Well, that's not a "national" problem, but is dealt with by labour and employment legislation, regulations and standards. While Remembrance Day is a national holiday and included in the the Canada Labour Code as one of the "general holidays" (i.e. paid holidays), that federal legislation is applicable, in essence, only to federal employees and those whose industries are regulated by the federal government. The Federal Government does not (and can not) dictate to the provinces how to regulate employment practices in their jurisdictions.
Or is your complaint that there are businesses open during the hours when Remembrance ceremonies are traditionally held? Again, that's within individual provincial jurisdiction.
Since it is already a "National Holiday" (i.e. so proclaimed in federal legislation which is the most that the federal government can do), what is your complaint and what do you want to happen?
