dilemma I found myself in two years ago.
I learned of Tim Morawetz' first book, Art Deco Architecture in Toronto about the same time I found that it was already out of print. I became a fan when the author generously gave me access to a PDF of the book, for my own research. We corresponded about some Deco delights in Tweed and Picton, and I was able to provide a bit of local content.
The topic of Art Deco architecture in Toronto was not broad enough for Mr. Morawetz, apparently, as he's now taking on the inter-war style across our wide country.
Vancouver. Yes, that Vancouver. The one with Burrard Bridge, Marine Building, City Hall's Deco detailing. Won't repeat it here (but if you've travelled the link, you already know the story.)
link to a Vancouver history website with more detail on this magnificent building's appearance in 1929, the best of buildings at not the best of times.
These will have to do, until you get a chance to see Art Deco Architecture Across Canada in person.
