This vase may be from Queen Victoria's Diamond Jubilee (according to family lore) or it may be Edwardian (according to caption with photo of identical one I found in Google search).
It is similar to pieces of Queen Elizabeth II coronation memorabilia I found on eBay.
It has Canadian symbols, but British flags.
My mother informed me it was rare and valuable at one time. I received it in this condition - worn rim and feet. One foot is chipped and another appears repaired. Ink marks inside suggest someone used it to hold pens.
