Terms and Conditions of Membership

CMS membership is based on calendar year, from January to December.

A CMS member remains in good standing if they renew their membership no later than March 31 of the current year.

Each CMS member will have a unique ID number and an online portal account that they can access member benefits throughout their membership.

Membership rates

  • All Membership rates are non-taxable.
  • For Non-Canadian addresses payment is required in U.S. funds.
  • Rates are subject to change without notice.
  • Membership fees can be paid in advance for up to 3 years to secure the current year’s rate.
  • A receipt is sent by email after processing is complete and can be used towards your NSERC grants or may be claimed on your Canadian tax return as professional fees.

Membership Categories

When renewing or applying for membership, you must select the most appropriate category that defines your current situation.

2-for-1 Membership: When signing up for a new membership, a 2-year membership for the price of 1-year will apply to all non-student categories. A new member is considered someone who has never been a member of CMS before.

Grandfathered New Member Category: This category (grandfathered as of 2019) was created to give a new member the opportunity to secure a low rate for a 5-year commitment; 50% of regular fees. This commitment can be paid up front for all 5 years or paid yearly. Any disruption in concurrent payments, the regular rate for membership will be owed for the year(s) of paid membership. A new member is considered someone who has never been a member of CMS before. Once the 5-year commitment is completed, your category of membership will be as a regular member and the fee based on your professional annual salary.

For all other category definitions, please see Categories.
