Used fish tanks in Thunder Bay typically sell for C$38 to C$285 (about $27 to $200). An empty tank is bought on volume, dimensions and the state of the silicone — it is a simpler sale than a full setup, and it lives or dies on whether the seals are sound.
Selling a fish tank in Thunder Bay
Thunder Bay is the port at the head of the Great Lakes, where prairie grain has been loaded onto ships for over a century, and it is the largest city for a very long way in any direction. Winter here is severe and the isolation is real rather than rhetorical.
Forestry, port work and the university all turn people over on their own cycles. Because shipping anything in is costly, goods circulate locally for far longer here than they would in a larger market.
Because freight from the south is slow and costly, check that any parts you might need are available locally before buying something unusual. It is the difference between a bargain and a project.
Thunder Bay, in Ontario, has around 110,000 people, which means a small local market, which makes the nearby towns part of your audience rather than an afterthought. Toronto, Ottawa and Brampton are close enough that a buyer there may well make the trip for the right thing.
Handing it over in Thunder Bay
Interac e-Transfer is the norm and is instant and traceable, which suits a private sale well. It is what most buyers will suggest before anything else.

Steady year round with an autumn and January lift. Standard sizes sell within a couple of weeks; very large tanks are slower because few buyers have the floor for them.
Listing is free and there is no selling fee, so the whole amount the buyer pays stays with you. You and the buyer agree the handover between yourselves.

Common questions
Where can I sell a fish tank in Thunder Bay?
List it free on WishThrift and deal with the buyer direct. Driving is essential and the city has two distinct centres from its amalgamation, so agree which one. Freight in and out is slow and expensive, which is exactly why buying locally matters more here than in the south.
Have you tested it for leaks?
Fill it, wait, and report what happened. An untested old tank is worth far less than a tested one because the buyer is carrying all the risk.
How much is a fish tank worth in Thunder Bay?
Most used fish tanks change hands for C$38 to C$285 (about $27 to $200). Condition and completeness move that figure more than anything else.
