That's a really complicated question to answer. First and foremost it'll depend most on the condition of the car, both mechanically and cosmetically. The complications of value arise when we talk about who is selling it as well as who is buying it. For now, let's assume, hypothetically, that the car is solid, and runs and drives with only tired/needing serviced cosmetics and mechanics.
If a dealer/cap flipper/auction house/consignment shop has is for sale, it's worth triple or quadruple more than the actual value. A lot of people like/want these cars, and given the jaw dropping prices some sell for, dealers, flippers, auction houses, and consignment shops will take advantage of that.
If it's a private sale between two private parties the sell price is usually acceptable and/or on par with actual worth. It's then only a matter of what the buyer and seller agree upon, which is usually a looonngg way from prices we see elsewhere.
Another fact to take into consideration is that there are many people who love a Pagoda and would love to have one.....probably more people than there are Pagodas available. However, there are more even more people that wouldn't own/buy one due to price gouging (sale prices, parts, etc), difficulty in finding knowledgeable mechanics, lack of modern amenities that people are currently used to, and difficulty in making one a reliable daily driver. This ends up leaving more of a supply of Pagodas than there is actual demand.
Another issue regarding value is that when dealers, flippers, auction houses, and consignment shops sell/list these cars for ungodly amounts of money people see those price amounts and assume that's what they're worth. Auction houses, dealers, flippers, and consignment shops are not the authority on value. Granted, many people will overpay because they have the money and because they feel that particular car is worth what they paid for it, but none of that reflects the median of value. It's private sales and what the average Joe is willing to pay for the car that determine a median price to go by. These numbers are rarely noted or taken into consideration. In this case, the average Joe and private sales are the majority, and the majority will take precedence over the higher numbers reflected from auction houses, dealers, flippers, and consignment shops.
Sadly, most people that sell a pagoda expect/ask a very high price. I'm excluding restored examples or low mileage examples. I'm making reference to good solid survivors that run and drive fine, but need cosmetics and/or a tune up. So to directly answer your question as to a value, I can only guess based upon your being in Canada. Not many people in Canada want a Pagoda, so demand is next to nothing....but that'll be in your favor. If this car is solid and needs nothing more than cosmetics or some engine work (light or heavy) you should be able to get it for $20,000-$40,000. I know that's a large spread, but at least you'll know what NOT to pay over.
There are periodical resources to gauge value, but most, if not all, heavily inflate those values. Especially Hagarty. Never ever use their price evaluation guides. They purposely inflate values so people will insure their cars for more, which means a higher premium and more money in Hagarty's pocket. Every price in their book is based solely upon auction house and car dealer sales prices. The sad part about Hagarty is that they allow people to insure their cars for whatever price they want. Also known as an agreed value policy. So say you insure your car for $80,000, but in reality it's only worth $20,000. Hagarty will allow you to insure it for $80,000, but when a total loss is deemed after an accident, Hagarty will not pay the $80,000 to you. They'll only pay within a median range of what the car is worth. They've gotten caught up in court several times regarding this, and every time they've lost and had to pay the full amount of the policy. They are extremely corrupt. For insurance use J.C. Taylor or Grundy.
If you want to look at a price evaluation guide then refer to Ron Kowalke's old car price guide. It's an unbiased and honest representation of a cars actual worth based only upon private sales (between private sellers and buyers, no dealers) and what the masses are willing to pay, and NOT auction house, dealer, flipper, or consignment shop prices. Alternatively, you can ask the fellas on this forum to chime in. Not all of them will agree on value, but there will be a good average to go by after it's all said and done.
