Energy (Oil & Gas)


Canada’s Energy sector has successfully and responsibly developed hydrocarbons for more than 150 years. The success of this industry has been built on entrepreneurship, innovation and the thoughtful management of the many challenges involved, including changing cost structures and commodity price fluctuations; the evolving technology required to access previously stranded assets; managing the environmental impact of such operations; working proactively with affected Aboriginal groups; understanding the ever-changing regulatory regimes; and working with other stakeholders to obtain access to new markets.

The offering Osler’s Oil & Gas Group provides to clients is simple, but all-encompassing  – we understand the industry and the marketplace in which you operate, we take the time to fully understand your objectives, and then we partner with you in creative ways to deliver on your objectives – on time and without surprises.
