According to the birth records on Manitoba Vital Stats Metro Waskul, b. 15/12/1905, Arbakka, MB Wasyl Waskul, b. 16/08/1908, R.M. Stuartburn Mother was Paraska Itnicky / Ilnisky These birth records were not registered until 1942 and 1943.
In 1906, the family looked like this: 3431Waskul MichaelHeadMM45 3531Waskul ParaskaWifeFM40 3631Waskul MariaDaughterFS16 3731Waskul MichaelSonMS6 3831Waskul IwanSonMS4 3931Waskul DmytroSonMS1
Also, living close to them, and probable family, are: 2729Waskul DmytroHeadMM41 2829Waskul ParaskaWifeFM34 2929Waskul MariaDaughterFS15 3029Waskul MichaelSonMS1
The census reference is; 1906 Census District:MB Provencher District (#7) Subdistrict:05 A (Townships 1, 2, 3 in ranges 9, 10, 11, 12, 13, 14, 15, 16, 17 east) Page 3

Seeing as these are the only Waskul's listed in the 1906 census and they are living close together and naming their children after one another I would expect Michael and Dmytro are brothers.
In 1911 they are still living in the same place. 1911 / Manitoba / Provencher / 36 Township 1 in range 8 east of the 1st M and townships 1 / page 17 26 165Woskul MichaelMHeadMOct186348 27 165Woskul ParoskaFWifeMJun187140 28 165Woskul MichaelMSonSJul190011 29 165Woskul TurinMSonSOct19029 30 165Woskul DmetroMSonSOct19056 31 165Woskul WasylMSonSAug19083
