Here are some more notable stops from the last couple of years.
CYGR ... Magdalen Islands Quebec. Quite a long over water segment so probably suited to twin operators. FSS on the field, they will,also help with accommodation and rental cars. Marvellous views and a great area to visit. You will find no tie downs or fuel so be prepared.
CYMX ... Mirabel Quebec, expensive but excellent FBO, FSS on the field one of most effective I have encountered. Mirabel was originally designed as an international gateway for Canada but was eventually abandoned to freight and industry. You are a long way from Montreal but for that big airport feeling without big airport headaches, nothing beats Mirabel.
