I've been using megabus to travel between montreal and toronto for the past 2 months. I've made 5 trips back and forth. Ticket price has ranged from $22 to $80. I give megabus 2 stars for three reasons. Number one, it's never reached the destination on time. It's been 25min to 3 hours late!!! Albeit it took 3 hours extra to reach toronto once because of construction on 401. However I am displeased that even with no traffic and no problems on the road (when I take 6am or arriving at 3am buses), we have never managed to reach on time. I'm lucky if I reach my destination 25min late. The average delay is 45min. I traveled in August and September, so weather was not a reason for the delays.
Second reason for 2 stars, their washrooms are terrible. Clean to begin with but very uncomfortable for females. Very cramped and disgusting. I just avoid drinking water or anything before and during my megabus ride, and try my best to avoid the washroom for the 7 hours or so it takes.
3rd reason is that the WiFi is weak and not reliable.
Aside from this, seats are ok. The buses have always been clean. Having charging points for each seat was great.
