Going Green: Reducing our Carbon Footprint!                                                            

As medical laboratory professionals, we are experiencing the move to a "green" environment in our places of employment. This past year the OSMT has been working to follow in these footsteps. We have reviewed all our printed processes and are making the necessary changes to reduce our carbon footprint.

For membership renewals you will have a choice between an electronic membership package or a printed version. We realize some members still prefer a printed card. We ask that you visit the OSMT member portal and update your contact information and communication preference. You can always call us at 416.485.6768, or email us at to let us know as well. If we don’t hear from you, we will email you your package.

Thank you for participating in our efforts to go green.
