Besides being right across the street from an excellent junior/senior high school McKernan station doesn't have all that much going for it. There are no public washrooms at the station and the hospital which I believe is the closest easily accessible washroom is still a bit of a hike up the street.
There is a stop in front of the station for the routes 106,4,and 313. The 4 is often a very packed bus but it is worth noting that it as well as the 313 will take you almost to the front door of the cross cancer institute which is nice if you or a relative are receiving treatment there it cuts down on your walking and time spent outside in the elements which can be important if you're unwell.
Being a surface station with no fully enclosed shelters can make it a misery in the winter. ETS likes to boast about the heaters they installed there but they installed them so high up to prevent things like vandalism that some days you don't even notice that they are on.
Honestly if you can find other connections to get where you're going that don't involve this station I highly recommend it. It is just a minimal surface station that gives off the impression that city council had some extra money laying around the year they built it and decided to use it on an LRT stop. read more
