  • Won a municipal tax case involving our client against a municipality. The municipality wanted to charge a substantial special tax onto our client for the construction of a new street alongside its building which was already bordering on a public street. Part of the by-law was found to be inapplicable, invalid and inoperative with respect to our client, since the latter did not benefit from the new street;
  • Won a case of disguised expropriation against the City of Lorraine. Isabelle acted on behalf of a developer who was affected by a zoning by-law change on his land. The City of Lorraine issued a Notice of reserve for expropriation. Upon expiry of the notice, the City maintained the amended zoning by-law without expropriating the developer but also without compensating him. The developer was granted leave to seek a fair compensation and the proceedings to set the value of the damages are ongoing before the Superior Court;
  • Acted on behalf of a landowner in an expropriation case to recover the fair value of his part of the land from which he was expropriated. Our client was awarded more than $200,000 in damages when the initial amount offered was approximately $20,000;
  • Acted for owners wishing to sell part of their farmland to a farmer and keep the part that is a maple grove. This case is awaiting the TAQ’s review judgment following the CPTAQ’s unfavourable decision;
  • Obtained an early settlement in a case where a bar owner had his license revoked because it had been mistakenly granted to him by the City. We initially assisted him in his attempt to obtain the right to a conditional use. After the refusal, an action for damages against the City was instituted and a prompt and satisfactory settlement was reached for the plaintiff;
  • First instance case won on the liability aspect in an action for disguised expropriation. The real estate developer was unable to carry out his project following a rezoning by the City of Lorraine making it impossible to use it for any purpose. The file on the liability aspect is currently awaiting a hearing before the Court of Appeal;
  • Won a case in a major judgment involving the expropriation of a potable water source. Isabelle represented the expropriated parties who were merely being offered a few thousand dollars to expropriate their water source. With the help of experts, Isabelle was able to demonstrate that the best and most profitable use of the expropriated parcel of land was commercial water pumping. Accordingly, she was able to obtain a significant indemnity for her clients. The judgment by the Tribunal administratif du Québec was affirmed on appeal when the Court of Québec denied leave to appeal in May 2018;
  • Obtained a settlement on behalf of a municipality in a looming major dispute with a real estate developer that was in receivership. A residential sector comprising some 30 properties, some of which were either already built or were being built notwithstanding that the public infrastructure was not yet completed or transferred to the municipality (streets and water treatment plant), was completed within a reasonable period of time and the claims from various parties were duly addressed without getting involved in costly legal proceedings;
  • Extreme diligence in the obtaining and execution of judgments (first instance and Court of Appeal) for the recognition of vested subdivision rights, thereby avoiding a demolition order for a newly built home and allowing the owner to preserve the value of his investment while the municipality was able to avert a potential condemnation to pay damages;
  • Obtained a settlement on behalf of a school board, thereby avoiding lawsuits further to a negligent oil spill on the grounds of an elementary school. Managing the implementation of the settlement, including the demolition of the school, the relocation of the students and the decontamination of the soil and groundwater. After the settlement, obtaining a favourable judgment on the motion by the oil delivery company for reimbursement of the performance bond validly cashed by the school board.
