What are the differnces between the universities in Russia and TRU.

I have admitted a lot of thinks that differ education in Russia and Canada. Students from Russia ends school at 16-17 years old, but Canadians students end it in 18-19 years. So Russian students enters universitie earlier then Canadian students. Another interesting think that differs is flex-time. In TRU I found interesting that students can change time of their's courses but in Russia it is not acceptable because we have straight course's time. In Canada most of the programms are for 4 years to study, but in Russia almost all the programms are 5-6 years. So I understood that Canadian education is more liberalistic in my opinion.
