I am not yet 100% comfortable giving up our office. But we have some extra desks and we are located in a very nice part of town. I think offering these to interesting local entrepreneurs might achieve a similar goal.
If you are en entrepreneur interesting in a space in Old Montreal, leave your contact info here and I'll contact you.
That could work great. I know a local co-working space here in Boston does an office-space trade as well. Maybe get in touch with one in Montreal and see if their members have any interest or if they offer a similar service.
