With the release of the 15th Edition of The Best LawyersTM in Canada, we are excited to announce the "Law Firm of the Year" awards in Canada for 2021.

These awards are given to a single firm nationwide for excellence in a specific practice area. The recognitions are based on several criteria, including feedback from lawyers recognized by Best Lawyers on the individual and firm-wide work, historical analysis of the firm’s “Lawyer of the Year” awards in this area, and peer-review scores for the firm's work in a specific practice area. This year, for the first time, we invited firms in Canada to provide feedback on significant matters in certain practice areas that highlight the practice and its strongest work.

Below are the firms that received this award and their specialty as well as highlights from their feedback.

"We are currently advising Canadian Natural on regulatory and Indigenous matters associated with their application for approval of the Horizon South application and the North Pit Extension application for the Horizon Oil Sands Processing Plant and Mine, a 250,000 bbl/day oil sands mine. We are also acting for Canadian Natural in relation to a judicial review application related to the North Pit Extension project and a regulatory appeal related to the approval of the High Temperature Paraffinic Froth Treatment project. We have provided legal and strategic support to Canadian Natural in their efforts to respond to the appeals. We also advise Canadian Natural on responses to Indigenous objections to applications for surface land dispositions, well and facility licensing applications and other similar matters for their thermal and heavy oil operations, and on responses to Indigenous groups expressing concerns about unplanned events and other matters associated with Canadian Natural operations."

Energy Law
Dentons Canada

"The past 12 months have been difficult for the Canadian oil and gas industry. Notwithstanding this, Denton's advice has continued to be sought by major players on commercial and regulatory matters related to the sale and purchase of upstream and midstream suites of assets, energy project development, and the regulation of energy infrastructure. Clients include Enbridge, Cenovus, Suncor, Husky, Pembina, Petronas, and Shell. Details of some of these matters are given in this submission. Of particular note is the firm’s prominence in matters relating to the midstream industry – both commercial and regulatory, which has been an area of recent growth. The quality of the retainers that the firm has won is testimony to the fact that Dentons is a recognizable leader, a “go-to” firm in the area because of the quality of our practitioners and the fact that our commercial and regulatory teams work together in a seamless fashion to give clients practical advice and successful outcomes."

"The husband obtained an order in Ontario that varied a Manitoba support order that was made under the Divorce Act. The wife brought a motion to set aside the Ontario order on the basis that the husband had not followed the correct process for varying a support order that was made in another province. The court granted the mother’s motion and provided a detailed summary of the provisions of the Divorce Act that deal with varying support orders that were made in another province.

Medical Negligence
Gowling WLG 

"In May 2018, fertility specialist Dr. Del Valle discovered that a cryogenic tank containing embryos belonging to 47 patients had low levels of liquid nitrogen, which likely compromised the genetic integrity of the embryos. Two class actions were commenced against Dr. Del Valle, his fertility clinics, and the manufacturer of the cryogenic equipment. The outcome of these class actions will be important in addressing some of the challenges apportioning liability in product liability cases generally. These actions also raise other interesting legal issues, including the procedural requirement to consolidate both class actions as well as the validity of releases signed by potential class members in exchange for free fertility services. As General Counsel to the CMPA, Gowling WLG plays an important role in these class actions strategizing and advising counsel representing Dr. Del Valle on how best to approach these issues with the plaintiffs and co-defendants. Given its experience managing other class actions, Gowling WLG has provided important strategic guidance to minimize the client’s exposure to liability and potentially substantial damages. Gowling WLG is also providing advice to counsel for Dr. Del Valle in exploring a resolution with the plaintiffs and negotiating apportionment between defendants."

"New Gold entered into a strategic partnership with Ontario Teachers’ Pension Plan (“Ontario Teachers’”).

New Gold will hold (i) an overriding buyback option to re-purchase and cancel Ontario Teacher’s right to convert to a partnership during the four year period and (ii) a right of the first offer for the life of the agreements.
