Have you considered moving somewhere else or just renting?
There must be somewhere in Canada where the real estate market is more reasonable, if you want to move out, maybe you should consider it.
There seems to be a bit of ambiguity on what you exactly mean by investing in 'real-estate'. There are a lot of unit-trusts that focus on real-estate, that would be fine, but buying actual property to rent out is a risky proposition.
Take the human element out of your investing and don't rent out your own place. Personally, I would rather consolidate your position with a well-rounded basket of investments and just move to a region with more reasonable properties to rent.
Renting is just the most responsible way for young people to live. I know you are thinking something along the lines of getting that 20-year mortgage as soon as possible so you can start paying it off, but I would caution against this.
If you rent you have much more control in living within your means. If you get a good job you can rent a place that you know you would be able to afford, if you lose your job, you can get out of the agreement much easier than if you have a mortgage.
If you do well in your job and you get regular raises you can again probably within a year move to a place that is every time one peg higher on the socio-economic ladder, you cannot do this as easily with a house.
Consider this money more in line with a 100K kickstart to a pension fund, you can later settle down and buy some property but for a 25 year old building a position is much better
