Yes, IMT Ghaziabad transcripts are accepted by ECA for Canadian immigration. However, the procedure is slightly slower than anticipated, and can easily take up to a couple of months before finally giving it out. You might also have to pay regular visits to your university for verification.
You can send a letter to the IMT management asking them to send a stamped and sealed copy of your transcript to your specified address. After that, forward the copy to WES Canada directly, without hindering their regulation by opening the stamped and sealed envelope.
You might have to hire a third-party service provider so as to speed this process up. Recently, one of my friends came across a service provider and they completed the work within a provided ETA date and mailed the documentation straight ahead to WES.
Other than that, you should also have a UG degree since that will help you achieve several points in the CRS.
