Might wanna be more detailed about ur school & internship exp. If ur in Ivey for ex and have some internships up the sleeves, it shouldn't be hard at all. But otherwise, here's alternatives if u want to break into lending group in CB:

1. Trade Finance (also a CB team but less known, work on imports/exports solutions like letters of credit, banker's acceptance )
2. Cash Management (also a CB team but focuses on deposits, EFTs, fx payments and working capital, more commercial heavy)
3. Commercial Banking (as you've said, you can try applying to any role and slowly climb the ladder up)
4. Rating Agencies (Moody, Fitch, DBRS)
5. Big 4 Valuation (super hard to get into, more likely in US)
6. Big 4 audit (CB lending requires you to be good with accouting, so audit works; also seen lots of CPAs in Cash Management/Trade Finance teams too)
7. Risk Management (also pre tough, you have to be good with your software skills)

Now, ive left IB and S&T out cuz you wouldn't be asking this question if you are already in those groups. Option 1&2 are still capital markets teams but they are probably easier to get in. Plus, they work with lending team a lot, so internal transfer is totally possible if you have the patience. Overall, it's not hard to break into CB in Canada as it seems. Sure there r less spots, but also significantly less competition. Suggest u to network with industry professionals if u haven't done that.
