Zymeworks Inc., a corporation currently incorporated under the federal laws of Canada (the “Company”), hereby requests, pursuant to Rule 461(a) under the Securities Act of 1933, as amended, that the effective date of the Company’s registration statement (the “Registration Statement”) on Form F-1 (File No. 333-217100) be accelerated by the Securities and Exchange Commission (the “Commission”) to 4:00 pm, Eastern Time, on Thursday April 27, 2017, or as soon thereafter as practicable.
