What we're about

Originally started as Markham Makers by Jay, the group evolved into Ylab, a maker space hosted by the David Dunlap Observatory in Richmond Hill (https://www.richmondhill.ca/en/david-dunlap-observatory.aspx).

Ylab is an incorporated, all-volunteer non-profit. That kind of thing is important when we want to rent a space, get liability insurance, open bank accounts...

MEMBERSHIP INFORMATION - just meetup, or makerspace paid membership

We use meetup.com for our discussion groups and announcements. All the meetup.com membership gets you is access to the forums and announcement emails. We don't sell or provide contact info to anyone else, and we don't sell access to the list. We may include information on other groups' events that we like... but only because we like them. We don't take money to do that.

We've been back at the DDO since April 1 2018. We suspended operations while the Town of Richmond Hill completed its acquisition of the site.

Membership has its privileges - and responsibilities. We are an all-volunteer organisation. Nobody gets paid. We pay rent and insurance We all work to maintain and clean the space, and we expect everyone to volunteer and help out in some capacity.

Full details on our membership can be found on our website about us page (http://www.ylab.ca/about-us/).


We are well equipped with ylab-owned and member loaned equipment. We feature laser cutter with a 24" x 36" bed, PLA and ABS 3D printers, oscilloscopes, soldering tools, amateur radio gear and a variety of other equipment. As membership increases, 100% of the funds go back into the space.

Use of some equipment requires passing an appropriate certification class or supervision by a certified member.


We host tech talks, classes and seminars at the DDO and in other location. Check out our blog entries (http://ylab.ca). Most importantly, we work on projects and help each other. It gets better every week.

We welcome anyone who interested in software, Arduino, 3D Printing, laser cutting, robot making and toy hacking, amateur radio and whatever else we can think of.

Our main website is http://ylab.ca .

All skills levels are welcome.

Maker Space Open House! At the David Dunlap Observatory!

David Dunlap Observatory



FULL AMOUNT OF FEE (we'll even eat the Meetup fee) going to Doctors Without Borders in support of their work in the Ukraine.


Come out to our open house, and see what the maker space is all about.
We'll be running demos of our laser cutter, 3D printers, CNC, electronics, Arduino and more. And making useful things out of other old things.

You'll see some of the projects our members have been working on.

And you can see a lot more about what we do on our website at https://ylab.ca

If you haven't been to the David Dunlap Observatory, it's also a great opportunity to get inside the administration building and see what we've been doing in the historic workshops.

Why are we charging $5?

  • We are limiting numbers. COVID is still a thing.
  • Because of the limited numbers, we don't want no-shows. A token fee seems to fix that problem.
  • To support a great cause - Doctors Without Borders.

Learn what a maker space is all about and join the fun!
