Well you can still stay calm for now and wait a little bit for AVO, but once it's going beyond this time, say like 8 months which I don't pray, you may want to involve the service of one of the registered Canadian immigration representative (Rep) at this point. Involving the Rep will help you go into the nitty gritty of your application and find out what is missing and why they haven't issue you the visa. Frankly speaking, applicants asking questions directly from those visa offices may not work or too convincing.
Let me give you my own little story -
I'm a Nigerian, presently living in Canada. Myself and my family filed in for this same Federal skilled workers scheme some few years back, though we didn't use the AVO , because then we were living in a different country, so we use the visa office designated for the country we were residence then. We thank God everything went smoothly as expected. But there was a family friend of ours then, we submitted our application the same time, and the responses from the visa office always come the same time (maximum 2-3 days difference interval).
As the process continues, we were requested to go have our medicals (almost the same time), this friend of ours even submitted his medicals say a month before we did ours. After 3 weeks or so after our medicals, myself and my family were asked to submit our passports for visa and our immigrant visas were issued. Then here comes this our family friend, one month passed, no passport was requested, 2, 3, 4, 5, 6, 7, ....months passed after his medicals, he wrote to the visa office then, no response and as you know, you can't go there
So he decided to employ the service of a registered Canadian immigration representative (Rep), this Rep was the one that told him that , the amount he claimed that he has as Proof of Fund (POF) was not in his account. Apparently the visa officers were just waiting maybe he was going to update his POF, and if the POF wasn't updated, they were going to wait for the 12 months and told him that his application was incomplete (or unsuccessful), and may need to start all the process again.
So this our family friend was able to update his file through this Rep, then it was going to like 9-10 months, after which he was issued his visa and he came to Canada barely 3 weeks to the end of his 12 months window period.
