Welcome from a fellow Canuck.
Harrison tents are overkill for 4x5, especially if you're traveling.
You may want to check out the frequent TO camera fairs put on by the
PHSC, you will pay less in Can$ for accessories and not have to worry about shipping and duties if you buy from the USA on fleabay. Plus, the sellers are usually photographers who will answer questions, so bring your gear and ask away. I no longer sell in TO, but I have sold at their shows and there were sellers specialized in LF gear.
