This isn’t an ad for the first brewery in Upper Canada but it is an ad for a brewery in the first edition of the Upper Canada Gazette issued the same date as stated in the ad. It is also not necessarily the first brewery in the colony but that might be a tight race. Steve Gates, sometimes comment maker around these parts, identifies Forsythe as building the Kingston Brewery in 1793, too. And, of course, it would post date the likely first brewing in what becomes Ontario by about 120 years given the Hudson’s Bay Company was packing malt in the hold on its first adventure in the 1670s. Plus, there was posssibly even commercially brewed beer in Niagara at least when the brewery was set up as the paper the first edition was printed on was from Albany NY meaning a cask or more of Albany ale may well have traveled the same journey as it had a habit of doing. It appeared on the lower right of the last page of the paper, the only ad in the whole first edition.
