How can I go to Canada, please do let me know please.. please ... please

I do not know what is your qualification/ experience. But, you can try to apply for Permanent Residence. If you search the net, you should be able to find the application. They have a points system. So, you can see for yourself whether you will qualify or not. I know many people who take PR and go to Canada, then find a job there and settle down. Good luck to you!

apply for a tourist visa, and eventually marry a canadian citizen.

I honestly can't tell you, because I was born and raised here. But good luck! It is an awesome place to live!!
