Is there any Arduino workshops in Canada. If not I would like to start one
You need to be a little more specific than "Canada" . . . it's a big country . . . sparsely populated, but big!
I will assume that since you did not respond to the “Arduino Interest in Toronto or Waterloo, Ontario” thread in this “Workshops” forum, that you are not located in South Western Ontario.
Where are you located in Canada?
Are there any hacker or maker club spaces in your area?
