I know access to chemicals is pretty limited in Quebec. You may have to resort to cutting back new shoots each time they regrow until the root system is eventually starved to death.

Ace Hardware here carries this little bottle of Bonide Stump Killer for $11.99. It has a little brush on a stem under the cap. So handy we bought 2 so we can each carry one around!
You can cut off a tree and treat the stump - it's dead. You can also treat green bark on young stems if you're in a hurry. Cut off later. You could also cut a groove in brown bark to reach the inner bark. One dose on the bark might not be enough for a larger tree though.
It's 8.8% triclopyr. We buy a bottle of the same concentration to use for refills. We love how handy these little bottles are! If you don't have Ace, check independent garden centers. Many of them carry Bonide products.
