This wiki will attempt to cover the ability to access various lounges operated by AC. Since many travellers are not familiar with the layout of Canadian airports, we will detail both physical access as well as rules.
Overview of lounges
AC has three types of lounges:
Locations & Physical Access
Lounges are in the following locations:

Note that most of the Canadian airports used by AC have separate areas for domestic, transborder ("TB", i.e. to the US), and international flights. MLLs are often referred to based on which area of the terminal theyre in, e.g. YYZ Dom is the domestic lounge in YYZ, YUL Intl is the international lounge at YUL. Except when connecting from a domestic flight to a TB/international one, you can only use a lounge in the area from which your flight departs. For instance, a passenger flying from YYZ to LGA cannot use the YYZ Dom MLL as CATSA will not allow them to access the domestic wing; a passenger flying YXE-YYZ-LGA could use the YYZ Dom MLL as they will already be in the domestic area on arrival.
YYZ, YVR, and YUL have segregated international departures areas. The international MLLs cannot be accessed before domestic flights. In other locations, a "domestic" MLL can also be accessed before international flights.
Please note that while the US is a separate country, it is NOT an "international" destination in the way most Canadian airports and AC are set up. You can NEVER access the international lounges when departing on a flight to the US. (Passengers connecting in YVR between a domestic and US flight and following the connections path will enter the international departures area prior to the US area and although can physically access the international MLL, you will not be admitted and will be directed to the US area).
Lounges in transborder areas are after US customs pre-clearance, and can only be accessed by customers travelling to the US.
Access Rules
MLLs
Can be accessed for customers holding a SAME DAY DEPARTING boarding pass (for a flight operated by AC or another *A member) based on:
Domestic Lounges can also be accessed by those ARRIVING on an Air Canada Mainline, Rouge or Express flight, for those holding 50K status and higher.
Signature Suites
Signature Suites require both (a) an eligible fare and (b) an eligible destination. Your flight must be a flight operated by Air Canada that is departing internationally from Toronto or Vancouver. It doesnt matter whether you bought the ticket through AC or if youre on an AC codeshare, or if your itinerary has other international connections. Unless your flight is operated by Air Canada, and is advertised as Signature Class, and is departing internationally from Toronto or Vancouver, youre not eligible.

It wasn't the only option. It was the only option you were happy with.

Signature suite and chauffeured transfer if ticketed on United?
Im traveling YUL-YYZ, connecting to DUB in paid business class (listed as P class on my receipt). The ticket was issued on UA stock.
Does anyone know if Ill be eligible to use the Signature Suite or for the chauffeured transfer to the Signature Suite from a domestic flight? In the past, my tickets have always been purchased through AC but for since my return from LHR to SFO is on United, I ended up buying from UA.
Thanks in advance for your insider knowledge!

Does anyone have information related to the following? We have Business Class Flexible Reward tickets in I class booking on AC equipment from SFO to YYZ with a two hour layover followed by a night flight on AC equipment from YYZ to GRU. Since the flight reward tickets were booked through the United Airlines website using MileagePlus miles, it looks like we are excluded from the Signature Suite by the following language. Am I reading it correctly? Thank you.
Only Aeroplan flight rewards booked as a Business Class Flexible Reward or a First Class Flexible Reward in J, C, D, Z, P, I booking classes are eligible for access. . . . Business Class flight rewards booked and ticketed by partner airlines, . . . will be excluded.

The booking for this reservation that is displayed on the Air Canada website, accessed by using the Air Canada booking code, and the printed itinerary from the Air Canada website, prominently state that these are “Business Class (flexible) tickets.” These words appear in large print taking up about 1/3 of the page just beside the flight information.

Because you didn't book through Aeroplan, it's simply showing a slightly different naming convention to refer to your unrestricted business class award, that Air Canada acknowledges that they will transport you on.
A better example to reinforce my point would be through a recent experience where I booked an economy class ticket via Expedia. You might know that Air Canada has Flex (a restricted economy fare) and Latitude (an unrestricted economy fare) fare brands when booking directly through AC. When you book a full fare (Y/B) through an online travel agent, and look up the reservation on AC's site, it'll show up as "Economy (flexible)" (note no hyphen, parentheses, no Economy "Class", and no proper noun for fare brand) because the website doesn't infer the fare brand at this point when showing the fare you booked...probably because I wasn't presented with the brands when booking through non-AC
Your business class ticket happens to be a flexible ticket that UA sold you, but it's not the Business Class Flexible fare brand that AC sells you allowing you entry
Of course, all this is moot if you have a paid business class fare to an eligible Signature Suite destination, regardless of who issued the ticket. Air Canada can obviously detect that, and you deep down in your heart would know you'd be able to enter

YYZ MLL Entry Requirements
Good afternoon,
Was flying out of YYZ to LIS a few weeks ago in Lufthansa economy class. I have a CIBC Aeroplan Visa infinite privilege card, which as I understand entitles me to MLL lounge access in Toronto. However, after talking with the international MLL agents, I was denied entry because my ticket was booked with Lufthansa, not AC. However, I don't see anything about this in the Credit Card Terms and Conditions (it just states that you need to have a valid ticket w/ Star alliance). I was wondering if this has happened to anyone else / if it was a valid reason to deny entry.
PS. after reproaching them and showing the terms they let me in... but still said it was technically against the rules.

I'd write in on this - you probably won't get anything but it'll give them a chance for retraining. I had similar issues at the YVR transport MLL years ago every time I tried to guest a pax on another *Alliance flight than mine (agent insisted they had to be on the same flight). Wrote in a couple times, and then it never happened again.
(side note, I believe the official *Gold rules for partner lounges have changed that they have to be on the same flight, but AC still allows any *Alliance flight)

Before writing in the important question to answer is if the AP# was linked on the LH res.
1 The Aeroplan number of the person accessing the benefit must be included in the qualifying reservation, and the name on the airline reservation must be identical to the name on the Aeroplan account of the traveller.

I was able to, travelling on AC a couple of weeks ago, guest a colleague travelling on UA the United Club at SFO T3 using my AP *G. The only condition the lounge gatekeepers gave was that my colleague had to leave when I did because he was my guest.
