This is a pretty thin field. I don't think any Ontario brewer has a regular LCBO listing of a porter outside of Mill St. Coffee porter. Any recommendations for Ontario brewers? Here's what I know about:
Great Lakes: I think they do the most. Personally, I like their simple porter which has ton of flavour for 3.7%. Many other good ones like Harry Porter, Vanilla Bean Harry porter, BA porters.
Mill St Coffee Porter: It's good but the coffee is very prominent to my taste so it's not something I pick up often.
Clifford Porter: I loved this on a nitro tap at the Craft Beer Brassiere. Bartowelers tell me to forget about getting this at Innocente as it is only contract brewed there.
Black Oak: Nutcracker Porter - This is a good seasonal porter and is flavoured with baking spices like cinnamon.
I wish Duggan's was still doing a porter and I think that Junction would do one but I've only ever seen Stouts and Brown ales there. Any other suggestions on where I should travel on fall road trips?
