If paying the incorporation fee of $300 is a roadblock in incorporating, then you probably want to research how much it costs each year to keep your companies charter active with the province and filing your yearly T2 . Which if you use an accountant can run up to $1000

I was like you some accountants will quote you some crazy amounts while others will charge you as low as $25-50. plus incorporation fee!
I think it's not possible for less than $300. In Ontario, you have two different ways to incorporate your business. You can either manually make and file Articles of Incorporation or you can use a licensed third-party portal to incorporate the business online or electronically. But I should say, you better incorporate your business with the help of a service provider to avoid mistakes and to make the process is fairly simple. Also, there are categories such as Federal incorporation and Provincial incorporation, so you may get confused about the merits and demerits of these two if you incorporate your business manually.
