Tom Thomson Park In 1972, the then March Council had given the Kanata-March Horticultural Society permission to hold a contest to decide a name for the small park directly to the north of the fire hall. This park would be landscaped by the Horticultural Society. Their plan called for use of native trees, shrubs, roses and bulbs in such a manner as to be both a decorative asset and useful planting resource centre for the community.

The Council had stipulated that the name chosen must be that of a Canadian poet or artist. The entries submitted included a short paragraph stating why that name was chosen and why it is a suitable name for the park. The winning entrant was Patricia Currie.

The name Tom Thomson Park was chosen after Tom Thomson, Artist, Woodsman and Guide, who drowned in Canoe Lake in 1917. He lived humbly but passionately with the wild.
