Great minds think alike. I usually go to the Montreal Biodome in the late winter/early spring for similar reasons.
This year, it's closed until the summer for renovations.

The Montreal Botanical Garden is just around the corner though. Definitely worth a visit.
This place looks incredible! I'll have to add this to my list for my next visit to Montreal. Thanks for the link!
Assuming you have a rental car, here's one last link to the Sugar Shack run by the owner of "Au Pied de Cochon" <-- Which I also recommend.

Oh, this would be fun! I think I've seen this on an episode of Anthony Bourdain's show. Thank you for the link!
Montreal Biodome
The Montreal Biodome (French: Biodôme de Montréal) is a facility located at Olympic Park in the Montreal neighbourhood of Mercier–Hochelaga-Maisonneuve that allows visitors to walk through replicas of four ecosystems found in the Americas. The building was originally constructed for the 1976 Olympic Games as a velodrome. It hosted both track cycling and judo events. Renovations on the building began in 1989 and in 1992 the indoor nature exhibit was opened.
