Canada 3000
 

Will be flying Canada 3000 from Toronto to Lisbon. What's this airline like? I know there there is a baggage limit of 20kg per passenger. Is it enforced? (The fare was nearly half of CO, BUF-LIS.)

Look in the Air Canada forum for all sorts of comments. It was a charter airline now becoming semi-scheduled and calling itself a "leisure" airline. As a result, service is very basic and seating apparently is fairly tight. I do hear the baggage limits are rather tightly enforced as it's how the airline gets additional revenue.

You might want to consider paying for an upgrade to "business class" which is more like domestic first class.

You also get AAdvantage miles.
