"we got our pr and after one month of PR i got separated".
It's an amazing coincidence. Your genuine relationship lasted just long enough for you to get legal status in Canada. It didn't end earlier (which would have stopped you getting it), and it didn't end later (with you still together). Now that may be true. Fine.
It's worth noting, your timelines are wrong (somewhere) - at various points, you've said you got PR in April 2016, then a month later (May 2016) you separated, you were separate for a year as required then already got divorced. The earliest that can happen is May 2017 (2 months in the future) and you say it's already happened. So either you got your PR earlier, or you separated from your partner before you got your PR. You might want to get that straight.
Next, as soon (or possibly sooner) as you're allowed, you're trying to bring in another overseas partner. 15m men in Canada, and none of them are as good as someone from overseas. That's also fine, it happens to lots of people - most people in this forum! But you're now starting to stack things on top of each other.
It is entirely possible that your general story is true (all the specific dates can't be - see above) - you had one genuine relationship that failed, you have another genuine relationship now. But most people don't have that happen. Relationships fail, but not often around very important dates. New relationships happen, but not often right after another one finished. People fall in love overseas, but not often twice in a row, one of which gave you status, the other of which needs you for status. This means there will be doubt around your application. It won't be refused automatically, but you'll need to include clear proof about the genuineness of the relationship, and your last relationship's breakdown. And you really want to be clear on the dates things happened.
