The earths environment is very hostile on meteorites. Meteorites usually contain - among other minerals, Iron.
Meteorites quickly rust out into rusted shells and wither away.
The oldest meteorites are found in Antarctica and can be as much as 700,000 years old but that is because Antarctica has conditions that are extremely good for preserving meteorites. The meteorites of the Sahara Desert are often 40,000 years old because the dry environment lets them survive for a long time. Unfortunately, Canada does not have conditions suitable for preserving meteorites. The wet and freezing conditions means that a meteorite most likely would not survive more than a couple hundred years and the fusion crust would most likely not survive a decade. There are Meteorites rusting away in the ground though just waiting to be picked up.
