i'm in sherbrooke. market is pretty hot right now (good multi family deals are sold within days if not hours of listing). most people use centris.ca to list
appreciation hasn't happened yet like it has in montreal/toronto/ottawa/vancouver, so its still possible to get good deals approaching the 1% rule (monthly rent = 1% of purchase price) but these properties tend to go quickly.
also there's quite a bit of new development happening around the outskirts of sherbrooke, population is growing but maybe not as fast as new dwellings are being constructed. i've seen rental listings where the tenants are offered a free month's rent to sign.
i've been renting for the past 5 years in sherbrooke. i payed $420/month (nothing included) for a 3 1/2 from 2014-2017 for a property in murray st. (fleurimont, which is the eastern part of sherbrooke). right now i'm paying 875$/month (nothing included) for a large 4 1/2 (new building) on thibault st. which is further from downtown but the property is much nicer. before that i was paying 675$ (heating, electricity included) for a 4 1/2 on rue Grand Monts.
so to summarize yes the market is good for rentals and more people are starting to notice. triplex, quad, and 5-plex are especially attractive if you can get the right deal.
there's a large ($100 million) project currently underway to transform wellington street's downtown core (link below). something to keep in mind, if you plan on buying near that area (can probably expect some good appreciation as the project progresses).

feel free to message me if you have any more questions about sherbrooke, i'm currently closing on a duplex (in sherbrooke) that i'll be living in next year, i'm actually just getting started in the real estate market here but i grew up in the area so i know it quite well.
