How do I cash out a bitcoin in Canada?

Good afternoon, I'm a Canadian resident and I've been investing in Bitcoin for some time now. However, I'm not quite sure how to cash out my Bitcoin holdings in Canada. Could you please guide me through the process? I'm particularly interested in understanding the various platforms or services available for converting Bitcoin to Canadian dollars, as well as any associated fees or taxes I should be aware of. Additionally, I'd like to know if there are any security measures I should take to ensure the safety of my transactions. Thank you for your assistance in this matter.
