IS CANADA EVEN WORTH IT

I'm planning a short 5-day trip to Canada for a holiday and I can't fucking decide which city i should go to, I heard people say Toronto is shit, Vancouver is shit, Calgary is shit. SO WHERE THE FUCK? Banff looks decent, but I just can't be fucked with the travelling and since it's only 5 days it would be a pain since I have to fly to a different city then some sort of transport to banff which is rougly 1-2 hours. Too much hassle really. 

Montreal is probably the most decent looking, heard the night life is quite fun and not as dead as in Toronto. I'm going there in October so like enough time to think it through but like fuuck...
