Yes. Many Canadian homeowners have a HELOC alongside a mortgage, either as part of a combined readvanceable product or as a separate secured credit facility. The amount available depends on the equity in the home and lender qualification.
A HELOC is revolving credit secured by your home, so you can borrow, repay and borrow again up to the limit. Refinancing replaces or changes mortgage financing and may offer a lower rate for a fixed amount, but can involve penalties and setup costs.
