First time searcher need help with capital stack (raising capital) for target acquisition

Hey everyone, I'm a self-funded searcher in the later stages of evaluating a BC-based (Canada) B2B SaaS company in the EdTech space roughly $5-6M in revenue with ~$1.2M EBITDA and strong recurring revenue metrics. My background: Born and raised in Canada, American-educated (Master's from Georgia Tech with a Duke MBA, my wife is from Boston and I split my time in-between). Currently a CRO at a B2B SaaS company (~$12M ARR) leading a distributed sales & marketing across multiple offices. The target aligns well with my experience in revenue operations, customer retention, and go-to-market strategy. Where I need help: As most of you know, Canada doesn't have an SBA equivalent (maybe BDC), so I'm working through how to structure the debt side of this deal. My working capital stack assumes: ~50-55% senior term debt (BDC, Roynat, Big 5 bank?) [open to suggestions] ~20-30% mezzanine/subordinated debt ~10-15% seller note ~5-10% buyer equity [also need help] For those who've closed Canadian deals in this size range how did you source and structure senior and mezzanine debt? Any lenders you'd recommend (or avoid)? Lessons learned on sequencing conversations with BDC vs. Roynat vs. traditional banks? Appreciate any insights. Happy to connect directly if easier.
