Everyone loves Airbnb. At least when travelling, because you get an affordable place to stay that is usually pretty nice.\nBut when it comes to where you live, especially in Canada's major cities, Airbnb may be hurting your wallet more than helping it.\nREAD ALSO: Montrealers Are Being Forced To Pay An Extra $15,000,000 To Police Because Of Construction\nA study from David Wachsmuth, of McGill's Urban Politics and Governance Lab, is shedding new light on the impact of Airbnb on Canadian cities. And Wachsmuth's findings aren't exactly uplifting, especially for renters.\nAnalyzing Airbnb rental-data in Canada's three largest cities (Toronto, Montreal, Vancouver), the study found that there were 81,000 Airbnb rented in the last year.\nOut of the three cities, Montreal boasted the largest amount of Airbnbs.\nMontreal has 31,449 active listings. When comparing the city's total population the total amount of housing units, that makes one Airbnb listing for every 130 Montrealers.\nOr one Airbnb listing for every 58 homes.\nIn fact, in some Montreal boroughs where Airbnb is quite popular (Le Plateau, Downtown) nearly 2-3% of the area's entire housing stock are being made into temporary hotels. That's a huge percentage, by the way.\nIt's not hard to see why. Adding up the revenue collected by Airbnb hosts in the last year, the number is an impressive $430 million. That divides up to about $5,310 per host, more than a 55% increase since last year.\nMontreal is particularly lucrative when it comes to Airbnb, mostly because rent is already so cheap. Unlike in Toronto, where rental prices are nearly double that of Montreal, an Airbnb host in our city can welcome fewer guests while still making a profit.\nThe study cites Montreal's low rents and high Airbnb profitability as the reason why the city is the most active for Airbnb rentals in Canada.\nThat's great for some Montrealers, particularly those who actually own properties, but it doesn't bode well for the rest of us lowly renters.\nA total of 41% of the city's population lives in the Montreal CMA, which basically means the urban core of the city.\nThat isn't a surprise to anyone, but 91% of Airbnb listings are in the Montreal CMA, meaning Airbnb rentals are taking housing stock away from where Montrealers need it most.\nAccording to the report, in "well-established central-cityneighbourhoods" like Plateau-Mont Royal, "Airbnb growth is completely outpacing new constructions and actually reducing net available housing stock."\nTo take things out of the study and into the real world, take a look at Andrew Chapman's story. Out of the 9 units in his downtown condo building, all of them are being rented out on Airbnb. Chapman is the only person in his building that actually lives in his apartment.\nAnd it's not like there are enough new rental units to offset the growing number of Airbnb rentals in Montreal.\nMontreal isn't quite as bad as Toronto or Vancouver when it comes to the amount of new constructions versus Airbnb listing growth, but in certain boroughs, the problem is there. And getting worse.\nBasically, landlords are starting to see short-term Airbnb rentals as a more profitable avenue than long-term rentals. Evictions are already commonplace, notes a member of the Plateau Mont-Royal Housing Committee speaking to the CBC.\nIf this trend continues, according to the study, more long-term renters could be kicked out of their units to make way for Airbnb renters. Fewer Montrealers will be able to move into desirable neighborhoods.\nAnd perhaps most importantly, Airbnb "exerts upward pressure on long-term rents." That's academic-speak for "Airbnb will make rents in Montreal more expensive."\nIt isn't hard to see why. Airbnb rentals are already taking up a sizable chunk of Montreal's housing inventory, creating more competition between renters. More competition means landlords can increase the rent and still get interested renters.\nAlso, since short-term Airbnb rentals are so profitable in Montreal, landlords may need to jack up the price of long-term rental deals just to make the same kind of money.\nSo if you're noticing a major uptick in rent for an apartment in some of Montreal's more central neighbourhoods, you probably know who to blame: Airbnb.
