How to Sell


Gardner Galleries works closely with estate executors and family members to provide the highest level of professional service in the dispersal of estate chattels, from a single item to an entire household. Gardner's also accept items from downsizing, family division, antique dealers and pickers, discerning collectors and the general public.  We have accredited members of the CAPPA (The Canadian Association of Personal Property Appraisers) on hand specializing in various fields including Canadian and international fine art.  Our knowledge is based on 96 years of experience in the auction industry, today conducting over 120 auctions a year with 50,000 unique lots sold annually.  We evaluate items on a daily basis for private individuals and are the preferred choice for many trust companies, estate solicitors and businesses throughout Ontario.

We strive to obtain the best results for consignors, uniquely offering four distinct auction formats to expose items for sale to the largest and most appropriate audience: Fine art is sold at internationally promoted semi-annual online catalogue auctions (spring and fall), general merchandise in the bi-weekly Tuesday evening live auctions, weekly online auctions of specialized collections (art, jewellery, furniture, etc.) and onsite online auctions of full households or estates, sold right from your home. All online and live auctions are promoted on our website for several weeks prior to the auction start date with hundreds of photographs and detailed listings, advertised on social media (Facebook, Instagram) and other media such as the London Free Press. 

A recent sale showcased how our firm makes every effort to achieve results for clients.  Grant Gardner found a book hidden in the back of a closet for an estate with no immediate family and after weeks of research realized that the market for the book was perhaps two to five prospective buyers in Australia.  By skillful marketing and promotion he sold the book for $1,800,000.00 plus premium, instead of a few hundred dollars if it had only been promoted locally.

Acceptance of Items 

Photographs of items are acceptable for the purpose of free pre-sale estimates - send to  If you wish to send photographs by text please contact our office for instructions.  Auction estimates are also provided in person at 407 Hamilton Road during office hours on Thursday's from 10:00am to 4:00pm or by appointment.  Please call ahead to ensure an auctioneer is available to view your items.  For estates or most of the contents of a home, free visits to the home can be arranged for a general overview and estimate of total value.  Prospective consignors are encouraged to have a Gardner's representative give an idea of value before sending items to auction, as our knowledge of the auction market can provide insight on what results may be expected.  Our policy is that we will not accept any items after they have been offered for sale previously, such as from a house tag sale or Kijiji.  Gardner's knowledge of value, as with any fine art and estate auction firm, is a primary asset not to be wasted on leftovers from amateur sellers.

If a written appraisal is required the fee is based on a competitive hourly rate.  Appraisals are conducted for probate, insurance and fair market value by accredited personal property appraisers.  Refer to our appraisal page for more information (  

Once items have been approved for auction our office hours for receiving consignments are Wednesday, Thursday and Friday from 8:30am to 5:00pm.  The loading area is located directly behind our building off Rectory Street and there is always staff available to assist in moving heavier items such as furniture.  

Pickup and Delivery

As part of our goal to provide exceptional customer service throughout the entire auction process, we can provide for a reasonable cost our own staff and moving van for shipment of items.  We also work with local cartage agents who can assist with the moving of large estates and households to our premises.  

Commission Rates

Commission rates include everything except cartage. Unlike many other auction houses there is no extra charge for photography, insurance, internet listing, cataloguing and advertising.  

The standard selling commission rate is 25% with a minimum total consignment value of $500 - special circumstances, including where the overall quality is above average may result in a lower quoted rate; where the overall quality is very low, the result may be a higher rate or refusal of the consignment.  


Payment is processed 14 to 28 days following the auctions. Consignors receive a computerized printout of the results with an itemized list of every lot sold. Reserves are only accepted if less than our pre-sale low estimate. If the item(s) does not reach the reserve, a cataloguing charge is applied.

Gardner Galleries is the only auction firm in the London metropolitan area dealing exclusively with art, antiques and estate furnishings, recently handling sales for TD Canada Trust, Scotia Trust, BMO Trust, Public Guardian & Trustee, Oak Trust, Royal Trust and many others.
