look this whole process is very simple;
you have 3 type of ppl sponsoring their husbands
1) who actually lived in a same country 2gether and met thru a common friend or from work and they fell inlove n go married,they didnt just apply for immigration the 2nd day, they wait for a few months to gather things and make everything ready and then apply for immigration, this for one shows the IO that they didnt just gett married and apply for immigration the next day.
2)those who get into arranged marriage.
and
3) those who met online spoke on the the internet for a certain amount of time and then the sponsor travels to the sponsored person country and gets married, and then back to canada.
usually ppl from the 1st type are not required to send hundreds of photos and chat logs and whatever, as for the 2nd type use they have to because they have met online and all their relation developed via internet so the IO needs proof of that.
i know ALOT of ppl who got thru this with NO photos, and i know ALOT other who supplied several Kgs of evidence, around a thousand photos and hundreds of chat logs and such and they got refused, there is no general rule, each single case is different the only rule here is be honest and simple and ull get thru.
