Who has sponsored BSDCan so far?

BSDCan - The BSD Conference

Come join us at the 20th annual BSDCan!

BSDCan, a BSD conference held in Ottawa, Canada, quickly established itself as the technical conference for people working on and with 4.4BSD based operating systems and related projects. The organizers have found a fantastic formula that appeals to a wide range of people from extreme novices to advanced developers.


  • Tutorials: 29-30 May 2024 (Wed/Thu)
  • Conference: 31 May - 01 June 2024 (Fri/Sat)



There will be related events (of a social nature, for the most part) on the day before and the day after the conference. More details will be available later.

During the conference, a group for family members will be touring some of Ottawa's best attractions so your guests can enjoy the city. Plan to bring your loved ones with you!

Masks & public health

Updated 2023-10-30
Nobody likes masks. We don't enjoy BSDCan looking like a scene out of the latest Michael Crichton thriller.
However, BSDCan is about community, a community protects its most vulnerable members, and we have many vulnerable members. So, we are requiring that attendees wear masks (details below).
Finding a mask that fits your face snugly and comfortably before arriving in Ottawa can make wearing a mask during the conference much less aggravating.

BSDCan DOES require to you wear a mask:

  • in the conference venues (except for food/drink, see below),
  • that is well-fitted, and worn properly, covering both mouth and nose,
  • and that meets international medical and/or scientific standards:
       • meets N95, KN95, KF94, FFP2, PM2.5, or equivalent, and
       • no exhalation vent.
  • ...that's it.
  • BSDCan does NOT require to you wear a mask:

    • outdoors
    • outside the conference venues
    • during the closing social event (which is well-ventilated and open to the outside)
    • while you are the speaker/presenter
    • for the brief moment required to take a drink
    • while you are actively eating, if you are appropriately spaced out from other attendees

    If you have questions about this policy, please contact us before booking flights and hotels.

    If you are unable to wear a mask, we deeply regret excluding you this year. We hope you can participate remotely via the streaming options.
