Buses

Here in Finland, the buses are all equipped with a bit of space near the rear entrance (middle of the bus) to allow passengers with strollers or walkers.
Depending on what city you live in, you may or may not have to pay if you have a young child in a stroller with you.
In Helsinki, if you take the tram (sometimes known as an electric street car) with a young child - it's free.
In Jyv�skyl�, you do pay and it's increasing twice a year or so...currently it's 3,10� one way!  (Although your ticket is good for 1 hour - so you could transfer to another bus or take the return bus back if you can do this in time).

Here's a link I'd like to share about the buses in Halifax, Nova Scotia.  In the bus schedule book, it does state that you have to remove the child from the stroller and hold them in your lap, fold your stroller and prop it upright- to make space for others to sit.  Fair enough.  However, quite often, those buses are packed to the brim with both sitting passengers and standing (not to mention the odd 2-5 of them with strollers of a variety of sizes) - it's difficult to do this!
And if you don't own a stroller - quite often they are your savior.  I mean, your child is asleep in their stroller - and who wants to wake up a sleeping child (that is desperately in need of their afternoon nap?!)...there's usually a basket to hold some of your groceries or your coats and diaper bag....so who wants to remove all of that and occupy even more seats or floor space with all of those items?!

So I guess I'm saying, Finland has a way better bus system than Canada.  I've been able to squeeze in beside another stroller (without really squeezing) on a bus in Finland and not have a problem.  Thankfully, the bus routes I do take (occasionally) - are not very long, so someone usually gets off before another parent and their stroller need to get on!
