Looks to me like a typical Canadiana Oak dining set, c1920-1930. These used to sell for several thousand dollars, but I see them now for $500-800, although the china cabinet is the more desirable piece & it's good that you have all the leaves. If you can get a hold of a reprint of an old Eaton's catalog from the time, you will probably find your set. GG
ps, love the table decoration
