Congratulations on your engagement!
The Eglinton Grand has been know for it's historic vibe and Art Deco beauty for a long time and I'm sure it would be the perfect venue for an Art Deco/20's themed wedding.
We are not too aware of the details regarding the vaping laws in Ontario and how they relate to the no smoking in door law, as a result we cannot permit them on the premises. This is simply to avoid any issues with guests who are more sensitive to smells and smoke.
As an alternative you could always invest in cos play cigars, some of them are on the more realistic side and you do not have to worry about sensitivities, buying them in bulk will also be more cost effective for you.
I hope this helps, Thank you for your inquiry.
