Taking Job in Canada - Canadian Working Visa for Girlfriend/Spouse?

Hello everyone, Not sure if this is the best place to post this, but I figured I would give it a shot. Please move my post to the appropriate thread.

I am currently a Senior Manager in Credit Risk management working for a Fortune 500 company in the USA. My company has offered me a promotion in Toronto to a Director position.

My girlfriend is currently based in the US and we were planning to get married later this year/ next year. However, she wants to move with me and find another job in Toronto. My question is, what options does she have to get a visa for Canada with a work permit?

Can she move there and start looking for a role? Also, how difficult it it for someone working in the US on a H1B (her) to get a work permit for a job there?

For reference, I am in the US on a L1A visa. Is there anything I need to know before accepting this offer?
