My question is, what do I do with my dividends as they are in small amounts and cant be easily reinvested into most companies. Any advice on what to do with my dividends? and also any areas I can improve on regarding my portfolio.

Dividends may be small at the start, but you can always slowly accumulate them. It is like a snowball effect.

What I do is whenever I receive any dividends, I will put them into my warchest and track them. As time pass, you will realised that your dividends will grow from $100 a year to $1000 a year or more. With that, you can effective start to use your dividend to buy more stocks.

You are still very young, you can accumulate the dividends into a larger amount before investing it.

You could just wait, at this point no need to hurry. if you have invested more, the dividend sums will get bigger (and commissions bound to get to zero sometime ad in the U.S.) so then you will be able to advantageously reinvest

Since it's small, combine it with your RSP and plan to progressively increase your monthly investment amount.
