You don't have too many choices. Look at provincial nominee programs or the Atlantic Immigration Pilot Program if there is anything targeted for your industry.
There's really no best option. Canada's immigration programs are geared towards younger individuals. However there's still a chance for you to qualify and be selected - it's just going to be more difficult based on your age. Note that you can include your spouse and children in the application who are under 22 and unmarried. Children who are 22 years old or older, or who are married, cannot be included.
I would recommend you start by researching the Express Entry program (link below). This is a points-based program and those with the most points are selected. Right now you need to have 460+ points to be selected. You will need to determine how many points you have. If you don't have sufficient points, you'll need to look into the Provincial Nominee Programs.
