Wow, that is a loaded question in terms of cars/curves etc. As you know there are two basic types of Monorails...suspended like Wuppertal and straddled like LV and most systems you see world wide.
Bombardier actually has a very good design but has geared itself to the small airport/amusement sector or small downtown people movers. After the LV experience it had it doesn't broadcast their system. It is making a bid in for the new 100km Sao Paulo system so we will see how it goes. Bombardier has not put a lot of effort into it's marketing of it's Monorail because it has spent a small fortune investing in it's ICTS technology but with limited success.
Tekray built the Moscow and Tehran systems but the big ones on the block are Hitachi and Scomi.
In terms of expertise and systems geared towards mass transit they would probably be the most likely good options unless the feds or prov start using their powers of persuasion and will only build Bomabardier because the Monorail cars themselves are built in Kingston.
People often have these ideas of Monorail being much faster than subways but that is not the case. They have the only a slightly faster acceleration and top out at around 90 to 100 km an hour. In terms of speed they are basically the same. Most are automated but not all just like SkyTrain but subways can also be automated as well so there is no real advantage there except over LRT. Both , unlike SkyTrain cars, have subway width cars and are articulated. Hitachi 4 car trains are 3 metres wide and 61 metres long. 4 Hitachi cars equals 3 TTC subway cars so in it's case the idea that some people have of Monorail trains having to many articulated cars doesn't hold water.
Most have a curve of 100 metres and 6% grade over 400 metres. This gives them the ability to run elevated but decline quickly so that it is possible that the stations themselves do not have to be elevated but more like your standard LRT/TC stop as long as it has enough room to incline over the cross street. This can save a small fortune because the building of stations are what can really effect the price of any system.
Nearly all systems are rubber tired so they not only have less vibration than other standard steel systems like sub/ICTS/LRT but are much quieter which is a very big deal when going down railway corridors near housing or down major roads. It offers a smoother and quieter ride and hence easier to sell to local residents.........ie Weston
Monorails are the safest mass transit systems in the world. In the entire 20th century there were a total of only 4 deaths related to Monorails......all 4 on the old Wuppertal line. Due to complete grade separation they have near perfect reliability records. The Disneyland Monorail carries over 100,000 passengers a day and has a on time reliability record of 99.8%.
Another benefit of Monorail is that it is the only elevated or at grade system that has all of it's operating systems completely covered which can be problematic in other systems especially ICTS.
Monorails , due to having only one pylon have a smaller footprint than any other elevated system and are cheaper to build to boot. Part of the reason for this is using less material when building but the real savings is that most can be built off site. When the pylons are built all that is really needed is just stick them in the ground. Due to tight curves it is possible to avoid underground infastructure, unlike LRT, requires no overhead power source. It makes for fast instalation which also makes for fewer complaints from local residents about construction time.......ie Spadina.
There is another system in it's infancy with only one new line in Korea called
www.metrail.com as well as a suspended system that is under construction in Saudi Arabia called
www.monometro.com It has a great website with galleries and videos but note it has two rails so technically it is not a Monorail.
I hope this helps.
