Research & development
We have invested more than $2 billion since 2001 in Canadian pharmaceutical and vaccines Research & Development (R&D), with 89 million in 2021 alone. In 2021, we invested over $23 million into 45 active clinical trials across Canada involving 4,000 active subjects.

Community investment
We are committed to working in partnership with charities and community based organizations who reflect our key values, supporting programs with a local, national or international reach.
Environmental sustainability
In October 2018, we launched a Centralized Waste program involving the removal of individual waste containers from offices to promote environmental consciousness and reduce our contribution to landfills.
In November 2020, as a global biopharmaceutical company we announced ambitious new environmental sustainability goals in both climate and nature, aiming to have a net zero impact on climate and a net positive impact on nature by 2030, across our entire value chain – from lab to patient. We’ve set clear and measurable targets to help achieve these goals.
