What is the oldest tree in Ottawa?
Nobody can name a single oldest tree in this cluster, and picking one to look definitive would be dishonest. Three of the eight, both Vitifolia lindens in Major's Hill Park and the horse chestnut nearby, share the same roughly 125-year estimate, all tied to the same 1900-era planting programme run out of the Central Experimental Farm under William Saunders. The National Capital Commission's own register hedges every one of the three with likely and circa, and no second document dates any of them more precisely, so this page will not manufacture a winner among trees the same source treats as contemporaries. The other five, including the linden beside the National War Memorial, have no documented age at all. If you can date any of the eight from a photograph, a planting record or a park document, tell us and the answer here will change.
Ottawa protects trees through the National Capital Commission's own register, A Living Legacy: Remarkable Trees of Canada's Capital, compiled in 2020 as a curated survey rather than a routine inventory. It covers federal public land across both Ottawa and Gatineau, and for each tree it gives a genuine descriptive paragraph rather than a bare data table, which is unusually rich as sources go. What it does not give is numbers: no age field, no girth, no height, no vitality rating, so every measurement question this page could answer comes back as an honest gap rather than a figure. That shapes what this page can say about age in particular. Where the register's own prose ties a tree to a documented event, the planting programme William Saunders ran through the Central Experimental Farm around 1900, this page repeats that estimate with the register's own hedges intact. Where a nearby monument's date could easily be mistaken for the tree's own, as with the National War Memorial's 1939 unveiling beside the Response Linden, this page keeps the two facts separate rather than joining them into a claim the register itself never makes. All eight sit on open federal parkland with no entry barrier.
