Garbage dumps are close to the grid and the users.
Many of the worst offenders are very old wells, as much as a century old. Their original owners are long gone which is how governments ended up being burdened with capping them.
Like many old toxic mines, the creators of the problems have evaded legal liability by going out of business. Legal frameworks may be more rigorous now but the old wells and mines remain.
Some of the oldest wells, like the ones near Petrolia in SW Ontario, might be economically viable for methane power generation. Others in Saskatchewan and Alberta are likely not.
Flaring is much better than just letting the methane escape so it would be a better solution than doing nothing and would be a great stepping stone to a more permanent option. Flaring would be much cheaper than a methane generator or capture device.
Just put a methane generator on them and sell the power onto the grid. Its what many landdfills do with their methane.

Lots of industries just flare it when the winds are blowing the right way, ie: downwind of any Environment Canada sensors.
