In general, I don't think we do: witness the 401 as a prime example. If you build a road, I expect that you would build it for something like a 20-year traffic forecast. Counterexamples surely exist, but I don't think extra lanes are generally being built unless they are expected to be needed, as the cost is quite substantial.
In this case, this is really a mid-distance connecting trail that is likely to see few pedestrians commuting, and also relatively few using it for exercise. So I would say that it should be planned for that same 20-year traffic volume, but for bicycles, not cars. And it's quite possible that 3m is a sufficient width for that, if pedestrians are rare.
