Anyone have experience with IRAP grants (Canada)?

There are some posts already on this topic, but they’re a few years old now. Anyone have recent experience with receiving IRAP funding (Canada)? If so, I have some questions for you. In particular, I am wondering how accountability works (is the money sent upfront or is it contingent on developing/producing the final product? How flexible is IRAP to changes in the product/plan as development proceeds? How for-profit and with clear profit motive/application should it be?) and any other tips. Thanks in advance for your help.
