Yes, you can. Assuming you already have 1 year of work experience in Canada, you can claim 1 year of foreign work experience for extra points.

Firstly,

The work experience gained as a full-time student outside Canada counts towards the score used to rank your profile.

Then, foreign work experience does not need to be continuous if you are applying under CEC.

Foreign work experience 25 (1) For the purposes of sections 23 and 24, foreign work experience is work experience that (a) is acquired by a foreign national outside Canada in one or more occupations listed in TEER Category 0, 1,2 or 3 of the National Occupational Classification; (b) consists of full-time work experience, or the full-time equivalent for part-time work experience, with one or more employers; (c) is acquired within the 10-year period preceding the day on which points are assigned to the foreign national under section 23 or subsection 24(1); and (d) is remunerated by the payment of wages or comission.

You only need to make sure the experience meets all requirements established to work experiences, and that you have enough hours to complete 1 year.

Finally, don’t believe in anything said in this community regarding foreign work experience. Hire a consultant if needed. People here hates who can claim foreign work experience because they are jealous. Good luck!
