With all the discussion about the different papers, here and in another thread ..... here's some links to three products available in Canada. I think the parchment paper description makes it a match for Muv's greaseproof paper. It's pretty indestructible stuff so would be good for using in both steps that she mentions.
For the Canadians ... Your local HH can order it in for you, and have it in the store within a few days. While I haven't ordered these products, there's never been a minimum order requirement and they have gladly ordered just one, if it's not a standard item on their shelves.
