Expropriations Lawyers

Thomson, Rogers provides a full range of services related to expropriations and acts for both public authorities and land owners. Our lawyers have acted on some of the most significant expropriation cases in the country, including the Ataratiri expropriation and the Yonge Dundas Regeneration Project.

When retained by public authorities, our lawyers work with the staff and consultants to acquire land in a sensible and economic manner, identifying opportunities to mitigate and reduce the public authority’s liabilities.

When retained by land owners, our lawyers provide strategic advice respecting the proposed expropriation. Should the lands be expropriated, we pursue claims for the fair market value of the land taken, any injurious affection, damages arising from the relocation of a business, loss of good will, and disturbance damages.

Our lawyers understand that expropriation can be stressful and difficult for a business or home owner. We’re here to help.
