buying BUSD on BSD by Wire Transfer from Canada

I am in Canada and want to buy 30,000 BUSD on BSC using USD by wire transfer. According to the docs on Binance.com, I need to do that through Paxos. If I do that, will the BUSD I receive be on BSC or will they be ERC20, as last time I tried to buy through Paxos I ended up with REC20 tokens which I then had to bridge to BSC?

The link at https://www.binance.com/en/support/announcement/03ca064f796f4137bb1d9129ee71dde2 says I should be able to do it, but does not give any details. The link from there to a page with instructions goes to a 404

The support desk at Binance.com said I had to do it through Binance.org, but when I went there to 'buy crypto' it just sent me back to Binance.com and had a $5k limit.

I did previously buy BUSD by wire directly from Paxos , but ended up with ERC20 tokens, which I then had to bridge to BSC, but even that was not straighforward as there was a limit of $10k on the binance bridge.

So, please, can someone tell me the exact steps I need to take to buy $30,000 BUSD on BSC using a wire transfer from a Canadian bank?

Much appreciated!
