haha no dice my friend. from his rez it would take a good 20 mins to get to the train station via metro. followed by a good hour and 10 mins all the way to rigaud. and rigaud is a very very small town with no community buses or anything. and if you were to walk from the station, its a good hour walk if not more through ghetto houses. and no walkways.
not to mention the hill itself (Mont-rigaud), has one chairlift that takes 20 mins to get up and it takes 35 seconds to get down not joke. the slope is so flatt that you can cruise straight without moving an inch and not get anywhere near speed wabble.
What about the train that goes to St-Bruno? It doesn't get you right AT the mountain but I bet there's a possible way to get across the suburb to St-Bruno "mountain". (St-Bruno is reeallly small but has an Ok park and I'm pretty sure it pwns Rigaud)
