The Small Arms Inspection Building is not the obvious setting for a Sunday rummage. Built during the Second World War as a munitions inspection facility, the red-brick landmark on Lakeshore Road East now hosts one of Ontario's most distinctive monthly antique markets. The juxtaposition works — industrial heritage and layered domestic history make oddly natural company.

The Sunday Antique Market traces its origins to Toronto's St. Lawrence Market neighbourhood, where it operated for decades before relocating to this Lakeview site at 1352 Lakeshore Road East in Mississauga. It runs on the first or second Sunday of the month, from 09:00 to 16:00. The monthly rhythm is not accidental — it shapes the character of everything inside.

Specialist collectors tend to arrive early. Vintage cameras draw a loyal following, and the market has earned a genuine reputation among photography enthusiasts. Rare equipment such as the Plaubel Makina W67 and the Kiev 88 surface here with enough regularity to make the trip worthwhile. Beyond cameras, the spread broadens into mid-century furniture, vintage typewriters, art postcards and paper ephemera, secondhand clothing, floral curtains and the kind of decorative bric-a-brac that resists easy categorisation. General browsers find plenty to hold their attention too.

The dealers are a significant part of what makes this market worth the visit. Vendors at a monthly specialist event tend to know their stock well. Most are willing to talk through provenance, share the history behind a piece, or point you toward something you hadn't thought to look for. Negotiation is both expected and part of the culture here — sellers anticipate offers, and the back-and-forth adds energy to the floor. There is no admission fee to enter, which keeps the atmosphere open and draws a genuinely mixed crowd of dedicated collectors and curious first-timers.

The SAIB building itself rewards a few minutes of attention. Its scale and wartime purpose give the market a setting that a community hall or car park simply cannot match. Lakeview sits between Port Credit to the west and the Toronto city boundary to the east, making the location relatively straightforward to reach from either direction along the lakeshore.

Bus access is close. The Lakeshore Road at Dixie Road stop, served by MiWay bus lines 5 and 23, sits approximately 44 metres from the venue — as near as any transit stop gets. A further option, Dixie Road at St. James Avenue (bus line 5), lies roughly 200 metres away. Both connect into the wider Mississauga network, making the market reachable without a car for visitors willing to plan the connection in advance.

The Sunday Antique Market suits collectors with a specific interest more than it suits those expecting a large general flea market. Its compact size, monthly schedule and heritage setting give it a focus that bigger weekly markets rarely achieve. For anyone hunting vintage cameras, mid-century objects or paper ephemera in the Greater Toronto Area, this is a stop worth marking in the calendar.
