Mahesh, let's go one step at a time.
1- You, therefore, are not on the same case as the rest of us. Your status should not read "additional information" but something like "additional documents required", what we call ADR, which are 2 different status.
Note - We didn't get anything, you did and you knew what was required of you. According to my employer, they received a letter and the OINP office required confidential information they couldn't tell me. I suppose it is financial information about the company to prove they make more than $500 k or $1 million if the GTA.
2-Your email clearly shows there is a delay caused by missing documents, or actually, documents you sent containing errors, and they are a few critical ones. Click on the quoted message to expand, but in summary:
2.1- Incorrect date from your current employer, it should say February 2016 because of the T4. The letter says 2017. Note that the officer was nice pointing that out to you, they don't like to open files and dig information out, sometimes they just refuse and tell you to review everything, and you have to find yourself what was wrong. They have a certain Target number of applications to hit, and applications with errors delay them, so they prefer keeping their jobs and just hand it back to you.
2.2- The former employer said you worked part time in June 18 2015 and that you worked full time in June 1 of a non-specified year. Is it 2016? If so, you don't meet the criteria of having two years experience if using these 2 employers. **Is the correct date you started working as full time on July 1st 2015, not June 1st? Because you can't start working on June 18 and then get upgraded on June 1, as if the time moved backwards, unless you started as FT and changed to PT, which don't seem to be the case, it looks like June 1 is not the right date, and you should always specify which year. Since you changed employers, you should also specify the exact dates you left one job to the next, because two days on the weekend that you move from one place to the next is going to be discounted, so, let's say, someone starts working on June 18 2015 and apply June 18, 2017, being unemployed for 2 weeks ( I won't say 2 days, because I don't know if they count a year as 1560 hours of work or as 365 days being employed), that person will fail the criteria because of those 2 weeks and should wait a bit before applying.
3- It seems you didn't show enough documentation to prove you meet the prevailing wage of the function. They didn't say it clearly, but you should double check it.
4- Being employed does not count as a job offer. You should get a job offer saying it is full time, permanent, and the job offer should contain what is your function exactly, so they can see if it fits the NOC description. For example, a person who chops vegetables is not a cook, sometimes they apply as cooks or chefs and it is not valid, or, a MacDonald's supervisor apply as a restaurant supervisor or cafeteria manager, which is not the same thing. Those functions require no training and are not eligible. So you offer must describe the functions to avoid missing that item. In my case, it stated the function, item by item.
5- Finally, your application process is being withheld because of these errors you must fix quickly, if you haven't already, and then, after checking for completeness, they might contact your employers for "additional information". You are one step behind.
Got it?
Now a little bit of constructive criticism:
I wish I could help you more, but I have my own affairs to tender to. I took about 40 minutes to write this message to help you. If you still have questions, a forum on the internet is not the most appropriate and certain environment for that many concerns, or for leaving your phone number, as someone might misguide you or take advantage of you. I believe you should consult and hire a representative, because with about $200, you might save some money, as your $1500 you paid is not refundable. And be aware of fake consultants and money suckers who just take your money, don't actually help you or care about you.
Best thing to do is be informed and prepared. As one old saying says: "If you want something well done, you better do it yourself". Take some time reading and paying attention to the correct definitions such as ADR vs "awaiting information", read your contracts, check for dates, and if you really want to immigrate, keep track of your travels because stamps on passports are not always clear.
Wish you all the best.
